If they can't get through the shields you can sweep the flames low and cook a person from the feet up using the shield and the leg holes to funnel heat and toxic gases up to the enemy soldier. Either way the soldier is in a bad spot as the soft points in his super armor, audio pickups and optics would be fried leaving him blind and toxic gases and heat would mean he can't take his helmet off. If gets even worse if the soldier isn't carrying his own air supply.
Very interesting tactic. Heck, the flamethrower user can even fire at the opponent indirectly and use rooms and other enclosed spaces to his advantage. He could even use napalm. Project the liquid onto the field, then burn it when it falls through.
When the fields are merged, it's another game entirely though. His own flames would backfire.
The flames would also cook the armos optics, microphones, external antennas and anything else that's reasonably soft as well as forcing the air filter to work overtime to scrub the soot and heat from the soldiers incoming air. Not to mention that you might just overheat the generator and kill the shield entirely.
Beyond that a microwave gun would be nifty, you already have people carrying hefty power sources, magnetrons are easy to mass produce, and microwaves are easy to channel. Suddenly you're cooking the guy and frying his electronics with a rather light weight weapon that's drawing from resources you're already carrying. It has the bonus effect of making the enemies expensive shields worthless while being easy enough to make.
I'm trying to stay away from direct energy weapons, but a maser (microwave laser) would be possible... sadly, it is easy countered by a metal mesh worm over the ceramic plating.
You just forced the enemy to produce and maintain metal mesh overlays for their suits for the price of one maser per squad. You're now hurting them without even needing to fire the damned thing.
If that isn't practical for some reason you can always just fire explosive shells under the shield. As mentioned the shield will amplify the blast wave and send shock waves up the legs of the poor bastard you just hit. The greatest bit is these enhanced muscles will let you fire some rounds that pack a lot of punch so even if you land a bit short the blast will still possibly knock a guy over. If you aim long and/or high you've just knocked the guy backwards and bought time for a followup shot; think two to the shield one to the feet.
As I've said before, it is unlikely that you'll be able to get an explosive shell, or much of the explosive shockwave, under the shield from the side. Blasting the opponent to knock him over is a great, basics-101-how-to-fight-with-a-field combat tactic.
You could blast the opponent, knock him over, then merge the fields and shoot the guy before he can dodge in his unbalanced state.
Thud it into the dirt in front of him with a time delayed fuse or possibly even a remotely detonated fuse. Call it a gun launched mine or some such.
Or...
design possibility: The generator could be placed as low as possible, on a swinging mount. It would look like the hornet-tails of the mecha in Ghost in the Shell. Spoiler
Image
That would be good for stability, assuming a counterweight held out from, but bad for mobility. You would have a hell of a time going down a flight of stairs or turning around in a room with a big old tail hanging out back of you.
If explosives aren't working try using a big blunderbuss that fires a lot of mass at as much velocity as your soldiers can reasonable handle. The enhanced muscles and possibility of using a recoiless round mean you don't fall over and he does.
Not going to work. Whatever recoil you can handle, the opponent can stand up to it better.
One note on the physics: Momentum is transferred back to the generator. What happens to the direction of the force? Well, the new vector is drawn from the point of impact to the center of the field. This means a hit to the top of the shield will push the user down, while a hit to the bottom, at whatever angle, will lift him up. [/quote]

Not if you go recoiless, and that can be done in a few ways. One is just to have rocket rounds fired from a tube with both ends open and another is to have a heavy counter weight built on the back of each round that gets knocked out the back of the weapon while the main round goes zipping off into the enemy. The Russians tried the second concept with planes back in WWII, and the first concept is used in any shoulder fired missile.
Either way, swords aren't the answer to your question.
I'm pretty sure by now that they can't be used to break armor. They would make for a great secondary weapon though, especially shorter swords, because they can bat away the enemy's weapon, cut off vital components and be jammed into weakspots much easier than a gun can be accurately fired into. A glorified combat knife/dagger, if you may, and the pommel can be used as an improvised hammer to smash against the opponent to disorient him. A barrel and firing mechanism can't be submitted to the same abuse.
Melee isn't the answer in general, clever ranged weapons are. The first side to arm up with flamer throwers and point some anti-missile laser at the enemy troops is going to win the war.

I think a direct fire grenade is more effective. While it might not pack as much explosives as a mortar would, it allows a hit or miss situation with a hit being a certain K.O.
I strongly suspect you could design guided munitions to home on shield bubbles. Their structural properties strongly suggest some kind of interesting visual or thermal signature, to me at least.
I was visualizing a bit earlier the electronic aids the soldiers might use, and one of them I came up with was a millimeter radar used to continuously track any object within the field. It would provide millisecond reaction times against grenades and such penetrating the field, and would greatly aid during hand-to-hand combat when you can see even the back of the enemy. Heck, the detection system can be linked up to the robotic arms so that they automatically smack away incoming objects before the user even notices.
Plan B: chuck a grenade with an impact fuze instead of a timer.
I'll get to planes and transport in general in a bit. The short version is that planes become much more arcade-y, with extreme lift and weird-ass hollow tube ramjets and weirder-assed triple-staged pursuit missiles designed to catch the enemy's field and explode inside of it.
Artillery is only effective on a direct hit (full momentum transfer) or very near hit (maximal blast wave/field intersection). Shelling the area and relying on shrapnel won't cut it anymore.
Artillery is also effective at dumping cluster bomblets into an area (already common), or simply interdicting roads and such by physically damaging them so vehicles and troops can't pass (a major artillery mission). They also retain some deterrent value at keeping troops from staying in the open- even if the effective lethal blast radius is vastly reduced, that just means it isn't totally certain death to be caught out in the steel rain.

The recoil from being hit by an exploding shell is often less than the recoil created by firing it, especially for low velocity recoilless guns.

The main problem is that they're much bigger and unwieldier than a dagger- too much so to be a good backup weapon. There's a reason backup weapons are usually light, handy, and concealable things like daggers and pistols.
krakonfour wrote:One of the 'exploits' I was thinking of is ramjets. Air, once at a high enough speed, would not have negligible momentum values, and when facing an especially hard field (does not bend at all), will likely be stopped. The following wave of air slams into this immobile air, and hits the field again, with even higher momentum. This process is repeated until we have -back-travelling shockwaves continuously pulsing immobile air through the field. This air, at near-zero speed, can be fed into a carburetor with minimal additional features. Hey presto, we have a pulse-ramjet that has zero moving parts and begins operation at low speed, regardless of the tube's dimensions.
I'm not entirely sure this would work except at supersonic speeds, unless the field start's acting as Maxwell's demon while standing still. Getting compression of the airflow into the engine isn't the real problem that stops turbines or ramjets from being efficient...
The main catch is that these countries have huge demographic bombs and (in most cases) relatively feckless governments- so it is far from a given that they will manage the transition responsibly. It would be interesting to include in your 'rising regions' a few blatant failures that had the chance to manage the transition, but didn't do it properly, and are now pretty much the table stakes for the real players in the region's political game.
I did away with the 'main catch' through the magic of future history: What if these countries got functioning governments just when they needed them? As for the neighbours that did not succeed, I thought I mentioned the North African countries (for sticking with Europe) and Saudia Arabie from not reconverting away from oil.
Please make sure to be conscious of that shift in government and what long term effects it would have. What kind of people emerge from the ruins of a corrupt old order, in time to rapidly rebuild and remake their countries to face a new tomorrow? They may be rather odd.
Do you have any idea how expensive a modern war fought on industrial scale would be? Prestige just plain isn't enough to justify it.
Oh ho ho ho its unlikely that the cost of future wars in the setting will skyrocket. You ARE doing away after all with the tanks, APCs, gun helicopters and bombers.
You are NOT, however, doing away with expensive aircraft. Bombers can still hit strategic targets (a railroad bridge is too big to shield conveniently, and if it isn't, the power plant that sustains that shield is). Reconnaissance planes are still too dangerous to allow to roam your rear areas at will, as are strategic bombers and cruise missiles, so fighters are required- and all these aircraft still need the full panoply of expensive avionics that makes a plane like the F-35 cost more than its weight in silver.

Also... why are we doing away with tanks again?
Even so, you are right about the cost of a large scale attack. While there might not be any need for several expensive vehicles and ammunition, the sheer scale of men, equipement and supply train to provide is non-negligible.
Manpower costs are a huge fraction of the cost of an army in modern societies- the army has to pay people commensurate with the cost of civilian labor, and has to maintain numerous civilians for each soldier in the field.
I'll either think up of a good reason or handwave the question away with dick waggling contest mounting Indo-Chinese tensions.
You might want to rethink the nature of the war to be consistent with the actual extant motives for conflict in the setting, instead. You don't need the Great Asiatic War to have interesting things in your setting.
You also have to consider the extreme demand for India's growing high tech industry and the consumer base rapidly changing from third-world farmers into middle class people with Ipods and a degree, and future supply of minerals for decades to come is at stake.
Fighting a war with someone to make them sell you rocks at good prices is SUCH a stupid plan unless you plan to conquer them outright. There is no way in hell they'll make more favorable economic agreements after you bomb the crap out of them than before.
Yes- but either side would have strong incentives to use tactical nuclear weapons to avoid a major battlefield defeat. That's something I think you're missing- in a shooting war between nuclear powers it is very hard to imagine that.
Would they use nukes if the battle simply 'pewters out' once both parties agree on the trade conditions they are trying to impose on one another. I can imagine India holding China hostage with the war:
-Keep fighting and its going to cost you more than me
-Definitively close negotiations and I'll escalate to nukes
-Accept the conditions and we won't have to fight anymore
The main issue then is that China should have been able to see this coming- you aren't pitching their government as stupid. If they weren't willing to face confrontation with a nuclear power they wouldn't attack one in the first place. If they were the ones being attacked, they would threaten India with retaliation, and cheerfully try to suck Indian soldiers into attacking them in unfavorable areas. The Indian army would have to move thousands of kilometers to be a threat to core Chinese territory, giving them a very long supply line, much of it through bad terrain like mountains and jungles.
Very true.
It's also a war of attrition between Indian men vs Chinese equipment, since the latter have the technological advantage and prefer sending robots down the long supply chain than soldiers.
This doesn't necessarily actually work, because the drones require considerable maintenance teams and support structure in their own right- someone has to maintain the damn things even if they're being driven by guys with Xbox controllers in Beijing.
Plus, Chinese look bad when they use shielded drones to take down living soldiers.
By the time you are fighting a war on this scale, public opinion doesn't matter to speak of. Especially since China is not a democracy.
There's also the possibility of massive airlift operations, or the more likely one of Chinese forces already in position and at the Indian border before the war starts. The Indians drive them back over Pakistani land until they are pushed back against the mountains.
[Groan]

Massive airlift only makes things worse, because the transport planes are hugely expensive and relatively easy to shoot down- they just plain can't carry that much. The only historical cases of massive airlift being used to support large populations or armies were in cases where there wasn't an enemy in a position to shoot down the planes.

And prepositioned forces do little to explain how those forces are supplied. Fighting takes a LOT of supplies, and these supplies are consumed continuously by combat forces. No general staff worth their salt would preposition a huge army in a place they can't physically ship adequate supplies to.

See here for an example of this kind of problem dissected and analyzed, by a guy who plans things like military logistics for a living. [Whatever his faults, I don't deny his ability to do that math]

http://bbs.stardestroyer.net/viewtopic. ... 6#p3372356
And in any case, it makes for an interesting war. Chinese technological superiority clashing against the forces of nature, trying to replace the expensive battlefield drones, while Indians heroically sacrifice their lives against the cold machines of the enemy...
Except the Chinese have to be stupid enough to go on the strategic offensive by throwing money into a hole in the ground. What are they expecting to win here, anyway?
You are aware that under any vaguely normal conditions, one country does not export ALL its product to one other country? World exports are fungible; even if Kazakhstan did export all its uranium to China, this would simply mean China's demand is sated and the rest of world production is free to go elsewhere.
My idea was that China would threaten uranium suppliers with war or trade restrictions (like a meaner USA today) unless they followed its price-spike plan and refused to sell to the West unless they met exorbitant demands, first of which would be zero military presence in the vicinity, and second, total access to internal markets or something.
This is... very unrealistic. Resource cartel tactics don't work well if you actually try to lay down hard embargos on people for very long, because your precious natural resources lose all value in a hurry if you do not sell them to anyone. Once the supply shock has forced your rivals to stop using the stuff for six months, you may find that you've permanently damaged the demand for your product, and that your monopoly will never again give you the same leverage it used to.

You've got this sort of cartoonish "DO AS I SAY OR I WILL CUT OFF THE WORLD'S UNOBTAINIUM" image of how this kind of economic power actually works. It sounds like a cartoon villain.
Not ellipsoidal? Can you set it to be ellipsoidal?
Nope. The field is pushed out by the generator equally in all directions, so its equilibrium state is a sphere. However, a stick long enough inside the sphere will give it a lemon-like shape, depending on the malleability (elongated shape, bulges on the ends).
But two generators create a merged field?

That field would then be an ellipsoid- because it's being repulsed by the two generators, one at each focus.
I foresee a lot of people playing "catch" with hand grenades. Note that this will probably be how any "OMG SUPER BADASS" hand to hand combatants die- someone gets tired of them killing their buddies in sword fights and just starts standing back and pitching grenades to them.
Unless it is a very light grenade, it will be stopped if you throw it against the field. The user has a few milliseconds to seconds to step away from the falling grenade, which would then explode and transmit momentum to the target.
Solution: use an impact fuze, grenade goes off when it hits the shield. The grenade will be stopped by the screen just as sharply as it would be by a brick wall.
If it's a light soldier, you're in luck. If he's a heavy soldier with generator bracing meant to stand up to tank guns, then the explosion won't do much.
Solution: throw grenade, which stops and falls inside the shield in quite a lot of cases.
Heck, if he can carry hundreds of kilos with artificial muscles, armoring to stand up to grenades doesn't seem impossible.
Solution: throw larger grenades.
But that's all specifics. Grenade spam might be very effective in some cases, and completely useless against others. It's one tactic amongst many and I haven't tweaked the setting enough to favor one method over the other.
Not denying it- point is that this is exactly the sort of thing that I think a good author would do to rein in the stereotypical REIGN OF THE SUPER-SWORDSMAN crap. You're the world's greatest swordsman... the enemy brings grenades. Shit.

If the grenades are hitting the shield going too fast you could also attach a small parachute to them to slow them to below the shield's threshold for blocking stuff.

Hmm. Field hates passing through matter?

Drones dropping large cheap parachutes. If the parachute partially lands on a shield it sinks through, enveloping it and cutting the shield off. Sniper then has fun.

It somehow reminds me of modern tanks falling to a barrage of low-tech RPGs. While the crew remains safe, the tank is tripped of pretty much everything on the outside, it it becomes a 'soft kill'.
You just forced the enemy to produce and maintain metal mesh overlays for their suits for the price of one maser per squad. You're now hurting them without even needing to fire the damned thing.
A metal mesh would be an insignificant weight fraction of the suit's armor... but you are right, just the same way all optics would need anti-laser shielding even if no laser blinding is being used, or anti-chemical, biological, nuclear protection on military vehicles becoming a requirement way past the time where those are frequently used.
Thud it into the dirt in front of him with a time delayed fuse or possibly even a remotely detonated fuse. Call it a gun launched mine or some such.
The problem is, if he jumps and brings his feet up against the body, then the shield's bottom will close up and he'll be temporarily invulnerable.
Sideeffect: Jumping bunnies CoD shooters.
That would be good for stability, assuming a counterweight held out from, but bad for mobility. You would have a hell of a time going down a flight of stairs or turning around in a room with a big old tail hanging out back of you.
I was thinking more along the lines of between the legs for maximal stability, like a massive dick :roll: , but you are still right.
Not if you go recoiless, and that can be done in a few ways. One is just to have rocket rounds fired from a tube with both ends open and another is to have a heavy counter weight built on the back of each round that gets knocked out the back of the weapon while the main round goes zipping off into the enemy. The Russians tried the second concept with planes back in WWII, and the first concept is used in any shoulder fired missile.
That migth work, but then we'd start hitting problems of mass efficiency. How effective is all that you're carrying compared to the mass of the equipment used to counter it.
In this case, you're carrying a gun and ammo upwards of 100kgs, just to knock someone over, and it is easy countered with zero mass penalty by anticipating the shot and/or softening the shield to reduce the rate of momentum transfer to something manageable.
Melee isn't the answer in general, clever ranged weapons are. The first side to arm up with flamer throwers and point some anti-missile laser at the enemy troops is going to win the war.
Yes, in an age of guns and explosives, melee is ineffective. But when you're 3m at most from the opponent, and have mechanically enhanced legs capable of kilotons of jumping power, the prospect of getting within touching range cannot be ignored.

If flamethrowers become prevalent, then fire resistant suits have to be built, and that's not too hard (put sensors behind transparent ceramics, insulate the shit out of everything, use inert materials and build in a full water cooling and filetered ventilation system). They'd be like astronauts in the end, but if it works, why not?

As for lasers... I'm sure simple armor plating will win against 100kW-1KW lasers for a long time to come.

Yes, that would aid long-distance firing or throwing, but it also gives more time for the user to escape during the terminal phase, more so if he has advanced automatic systems to detect this sort of thing.

I must have worded it incorrectly.
It hates staying in matter. It will immediately reorganize itself to stay outside of solids at least, and liquids if they aren't moving around too much.

The parachutes are a great idea. It might not even have to be parachutes. Advanced anti-field shells would eject compact foam into its path, creating a hole to go through before impact. I can also see a situation where a soldier improvises with a blanket or something.

A soft shield would create a smaller hole though, and would cover the intruding matter much easier than a hard anti-explosion set field.
Borgholio wrote:Forget parachutes. Use high-pressure water cannons or foam.
Ah, two problems:
The field would halt the first wave of water, then intersect it when it has zero velocity. The following stream of water would crash against the immobile first wave and slow down too, and get intersected. Foam is even less dense than water. You'd need something like a glue gun for it to work, or a fluid that is liquid when in movement and solidifies if turned still.
Second problem is just how do you kill a guy when you have to devote so much stuff to simply opening the field? You'd have the mobility disadvantage when the fields are separated, so he might close in on you. You'd be severely disadvantaged if the fields are emerged.
Is creating a temporary hole, then shooting through whatever you're throwing at him, worth all of these disadvantages?

Why has no one thought up the idea of tossing field generators? Projectiles with an activated generator will just go right through the field.

And if the field gets slapped by a blast wave in midair, he lands sprawling as a turned turtle.

Other such things like firehoses aren't really common battlefield weapons; they're just something to factor in because people familiar with how shielded armor acts in combat will try it. Regarding the idea of water 'stopping' against the firehose, I think you may overestimate the degree to which this matters. The momentum is still transferred; it's just that some of it is transferred through the (rapidly flowing aside) cushion of 'immobilized' water pinned between the hose jet and the screen.

I would just like to point out that mortar shells can seriously damage main battle tanks with a near miss. There is little to no chance that anything which a human, even horrifically augmented can carry will be proof against say 82mm of HE going off right next to them. Also, 82mm bowling balls for direct fire action.
It has become clear to me in the previous days that any attempts at reconciliation and explanation with the community here has failed. I have tried my best. I really have. I pored my heart out trying. But it was all for nothing.

You win. There, I have said it.

Now there is only one thing left to do. Let us see if I can sum up the strength needed to end things once and for all.

Unless the field is visibly affecting the surrounding material, then no, it is undetectable, since it does not affect radiation under most configurations. A much more interesting target is the huge amount of heat being pumped out by the generator.
Plan B: chuck a grenade with an impact fuze instead of a timer.
Plan C: You have a millimeter radar and a quick-reaction onboard computer... a few onboard explosives and you've got yourself the walking equivalent of a TROPHY/ARENA system. It would be incredibly effective, considering that they only need to cover a miniature volume surrounding the user.
Image

On the downside, the suit would have silly-looking bricks like these all over the surface, allowing multiple launches in all directions of counter-explosive streams:
Image
Artillery is also effective at dumping cluster bomblets into an area (already common), or simply interdicting roads and such by physically damaging them so vehicles and troops can't pass (a major artillery mission). They also retain some deterrent value at keeping troops from staying in the open- even if the effective lethal blast radius is vastly reduced, that just means it isn't totally certain death to be caught out in the steel rain.
They'll retain their role as area denial, but at greater cost than today compared to their effectiveness. This might be compensated by the increased accuracy future technology would have ie. every shell is a guided missile.

I wonder however if any sort of artillery bombardment can render terrain impassable for foot infantry. If we go along the lines of shielded jeeps driving power armor around, then the troops can carry the jeep around any sort of terrain until they find something they can drive on again.
A suitable analogy would be SEALs troops carrying around their raft until they find water.
The recoil from being hit by an exploding shell is often less than the recoil created by firing it, especially for low velocity recoilless guns.
Excuse my english. What I wrote was agreeing with you here, since I was still talking from the POV of the firer.
Another consideration for the heavy weaponry argument is that the user of this equipment is lugging about hundreds of kilos of complicated anti-recoil systems just to knock some-over over. I think there's a limit to how efficiently you're using all this sort of equipment.

It would make sense that a vehicle or gun platform would mount oversized recoilless guns to drive away attackers on foot, but in infantry vs infantry combat, that extra weight matters.
By the way, this violates momentum conservation as it is now defined in physics so hard. Just saying.
Humm.
At the same time, the physics would have been violated enough with the teleporting momentum... When I see an object striking a field, I tend to imagine it being snooker. The cue hits the ball, and bounces away in a near-perfectly elastic collision.
The only difference with my field is that in a glancing shot, instead of a half-half distribution of momentum, all of it goes towards the object being struck.
I find it difficult to explain, but here's something to go on.
Image

True, but you have to take into consideration the reach of your objects.
You are 3m from your opponent. If both of you raise your arms and point your weapons, then you will not touch other.

You both fire, and the one with the better gun/armor combination wins after a few seconds.
This excludes scenarios where you and/or your opponent start the field merge moving, in which case you have a split second to anticipate the trajectory before you open fire.

Let's imagine that both opponents standing in each other's line of fire the THE situation to avoid. If the movements lead to this point, both opponents disengage and try something else, and at worst, they jump back and try and seperate the fields to reposition themselves for a more advantageous attack.

The Gun/sword combos come into play if you have a stick or sword long enough to allow you to touch the opponent's gun. With a quick swipe, you can mess up the aim, slide into the area he is not pointing at anymore, and fire at will.
The opponent will have to move his gun around and mess up his aim momentarily so that he can swing around at you once more. He can move backwards, but risks you doing the same and separating the fields. He can move into the area your sword isn't covering anymore, but risks YOU pointing your gun into this area in anticipation, leading to the scenario you want to avoid.

A counter to this method is to shoot with one arm as drawn back as you can, firing next to your ear or something. You'd position your sword in front to intercept the opponent's sword, and shoot when you have an opening. This swordfight will have nothing to do with today's swordfighting in the respect that you do NOT wish the keep your sword between you and the enemy. You want to keep the opponent's sword away from your gun or arms, and if his sword strikes you, it means practically nothing. The best move is to strike his sword out of the way, and move into the opening to disrupt his line of fire using a combination of your own line of fire and sword.

As this thing evolves in my mind, I find a few more counters and anti-counters.

You could use a weapon in both hands. This way you'd cover much more possible zones you opponent could dodge into, and aiming both slightly to the left and slightly to the right would remove the possibility of sidestepping just as the fields merge. The disadvantage is that your opponent has a longer reach than you, and can still nullify the advantage of a second weapon by overlapping one of your lines of fire with his own. Since this would lead to the undesirable situation, with two guns pointing at each other, you;d have to keep them constantly aiming at something else. This boils down to gun vs sword on one hand (literally ;) ) and an unsustainable gun vs gun on the other.

Another possibility is to use gun-swords, as in barrels built into the blade. You'd have the advantage of BOTH the long reach and the double lines of fire, but the new disadvantage of only being able to fire where you're pointing with with your swords, which is unlikely to be straight at the opponent.

One final possibility is field skimming.
I mean... you take a tiny step forward, the fields merge, you fire, and program your suit to step just outside of the limit for merging before you even finish firing. The bullets/explosive shells/mortar rounds/grenade strike your opponent, and whatever return fire there is is stopped by the now separated fields. Repeat from a different direction until you succeed.

I'm under the impression that it works much better at supersonic speeds. The incoming airflow would be powerful enough to send shockwaves from slamming against the immobilized front rushing back up the tube. This rarefies air behind the wave, and compresses it after, creating pseudo waves of air. These waves have a frequency. As the 'length' of air sitting still in front of the field increases (flow rate has an upper limit when starting from zero relative V, only increase is in pressure and density of the air), the shockwaves become muffled, or at the very least, less effective at creating sharp density differences in the incoming air. This is compensated by increased frequency of these waves.
In the end, they smoothed out into a pseudo-continuous flow of very high density cold, slow-moving air that would react perfectly in the carburetors. The rate of expansion of the gas under its own pressure would add to the exhaust velocity.

At very low speeds, a 'hard' field is required to create a sharp shockwave and start the process. At very high speeds, the field has to be 'softened' to accommodate for the increased air pressure threatening to destabilize the whole process.

Or it could be that I have no idea how ram-pulsejets work.

PS: I found what I was looking for: Acoustic resonance in the air, and this field-ramjet is a variant of the http://en.wikipedia.org/wiki/Pulse_detonation_engine, with the supersonic combustion caused by the high pressure oxidizer.
Please make sure to be conscious of that shift in government and what long term effects it would have. What kind of people emerge from the ruins of a corrupt old order, in time to rapidly rebuild and remake their countries to face a new tomorrow? They may be rather odd.
Don't worry, this is a worldbuilding thread and we'll get around to thinking of everything given enough time :)
What I see emerging from the rapid development of these countries would be a sort of ultra-optimistic super-consumerist nation that might look down on others for not succeeding like they did. We'd need a veritable fascination in education to make this work, coupled with the inevitable mass exodus away from the agricultural domain. Within society, it'd create a sort of education-tied class separation, and since education costs money, it'd be tied to wealth to a smaller degree. That might be better than a strict rich/poor divide, but since 'anyone can get educated and be one of us' to the uneducated is harsher than 'anyone can get rich' to the poor... I don't know. I'm sure the new Indonesian middle class would handle things differently than the rich Qatari foreign investors and the plethora of Gulf immigrants have in their country.
You are NOT, however, doing away with expensive aircraft. Bombers can still hit strategic targets (a railroad bridge is too big to shield conveniently, and if it isn't, the power plant that sustains that shield is). Reconnaissance planes are still too dangerous to allow to roam your rear areas at will, as are strategic bombers and cruise missiles, so fighters are required- and all these aircraft still need the full panoply of expensive avionics that makes a plane like the F-35 cost more than its weight in silver.
Very true, but at the same time, you have to remember that this is 100 years in the future, and nothing forseeable is slowing down the progress of electronics and computer speeds/hardware power.
Also... why are we doing away with tanks again?
Tanks: Highest velocity gun possible mounted on a turret, on top of a hull with all-terrain mobility and the heaviest armor allowed without sacrificing mobility too much.
Take away armor and replace it with a shield. take away the main gun and turret and replace it with multiple grenade launchers, and switch priority over to troop transport. I can't call that a tank anymore, and there comes a point in down-armoring where it becomes cheaper to create a disposable transport like a Jeep than a high-survivability one.
You might want to rethink the nature of the war to be consistent with the actual extant motives for conflict in the setting, instead. You don't need the Great Asiatic War to have interesting things in your setting.
I need something that both divides Asian geopolitics and sets up multiple conflicts around the surrounding zones. In my mind, the USA had its Vietnam, the URSS has its Afghanistan, and China has its Pakistan.
In fact, that reminds me. China and India don't even have to fight each other directly. China could make a military pact with Pakistan to help if stand up to Indian military pressure against its borders, in return for well... complete exploitation. Well, it's that or being taken over the big bad Indians, in their opinion.

Now, Pakistan is officially an independant entity with its own army. India could decide to invade Pakistan, or conduct a punitive strike of some sort, with casus belli being harboring terrorists, assassinating diplomats, unpaid loans, trade restrictions, pick one. India fully knows that the Pakistani-Chinese pact extends to having troops on the ground.

So this is how India invades Pakistan, but it's Indian soldiers shooting at Chinese soldiers with Chinese equipment while Pakistani civilians die.
Fighting a war with someone to make them sell you rocks at good prices is SUCH a stupid plan unless you plan to conquer them outright. There is no way in hell they'll make more favorable economic agreements after you bomb the crap out of them than before.
I... uh, messed up?
In the scenario above, India wouldn't touch any Chinese territory, and to the candid eye, India is killing Pakistani soldiers.
The main issue then is that China should have been able to see this coming- you aren't pitching their government as stupid. If they weren't willing to face confrontation with a nuclear power they wouldn't attack one in the first place. If they were the ones being attacked, they would threaten India with retaliation, and cheerfully try to suck Indian soldiers into attacking them in unfavorable areas. The Indian army would have to move thousands of kilometers to be a threat to core Chinese territory, giving them a very long supply line, much of it through bad terrain like mountains and jungles.
This sounds like a Germany vs Russia to me.
Russia has the advantage when driving out German soldiers within its own territory, but to move onto the offensive, it suddenly has the longer, more vulnerable supply chain.
This doesn't necessarily actually work, because the drones require considerable maintenance teams and support structure in their own right- someone has to maintain the damn things even if they're being driven by guys with Xbox controllers in Beijing.
Support structure, yes, but these things might also be the sort of nightmare drone people are scared of today: The stuff you airdrop over the battlefield, then let them kill all in sight until they break down or are destroyed. Chinese industry might find it more sustainable to rebuild the losses than to send a maintenance team 'over there' to recuperate and repair them. An infantry platoon can then wipe up the mess and disruption the drones caused, and do the detail work.

OF course, we run into the wartime crimes problem of leaving the drones activated after the fighting has ended, or dropping them into a built up area and expecting them to distinguish between civilian and disguised soldier. Bad stuff are going to happen.
By the time you are fighting a war on this scale, public opinion doesn't matter to speak of. Especially since China is not a democracy.
Not to the Chinese, but tactics like indiscriminate drone-dropping can help the Indian cause by rallying foreign support to its side. It'd also be grounds for countries pressured into playing along with China during the rare metal price spike crisis to withdraw and become more independent, or the very least end the Chinese monopoly over its markets.
[Groan]

Massive airlift only makes things worse, because the transport planes are hugely expensive and relatively easy to shoot down- they just plain can't carry that much. The only historical cases of massive airlift being used to support large populations or armies were in cases where there wasn't an enemy in a position to shoot down the planes.
Yes, but I'm not picturing China as being the winning side either.
In fact, this whole thing could be a lesson in humility. China thinks it can win a way solely by dropping drones into battlefields without any boots on the ground, then when it is pushed back, it believes its mighty airforce numbers are enough to continue the war by airlift.

Aircraft with fields are pretty much immune to non-shielded missiles and weapons. A conventional weapon has to match speeds with the aircraft to enter the field, which is pretty much impossible if it want to catch up with it. Field-deploying missiles might be rare at the start of the war, so China thinks it has uncontested air superiority. We might even see desperately stupid attempts of Indian and Chinese jet fighters unable to shoot each other down, so they practically play leapfrog and ram into each other, with a small chance of breaking away before all goes to shit.
During this period, airlifts would work.
Then, missiles are build with fields on them, the air war is brought back to sanity, and the previous airlift strategy breaks down.
Except the Chinese have to be stupid enough to go on the strategic offensive by throwing money into a hole in the ground. What are they expecting to win here, anyway?
With the Indian army crushed in Pakistan, or having at least suffered a severe blow, China can move onto putting military and economic pressure on countries previously protected by India, such as Afghanistan, Nepal, Bangladesh, and would be able to move into the Middle Eastern theater to complete WORLD DOMINATION hue hue hue I mean access the second biggest market in this world.
This is... very unrealistic. Resource cartel tactics don't work well if you actually try to lay down hard embargos on people for very long, because your precious natural resources lose all value in a hurry if you do not sell them to anyone. Once the supply shock has forced your rivals to stop using the stuff for six months, you may find that you've permanently damaged the demand for your product, and that your monopoly will never again give you the same leverage it used to.
No no no its not hard embargo.
Let's stay with Uranium for now.
China forbids Kazakhistan from selling its U238 to the West. China buys ALL uranium production from regions within the pact, giving away in the process dollars. Then, it becomes the sole supplier of uranium to the rest of the world. If you want to buy uranium, you have to buy it from China, at Chinese prices with Chinese conditions. You can still buy as much as before, but it will cost you everything else.
The best part is that China will sell these resources in yuans, so while the dollars it paid off to the cartel members devaluate, its own currency becomes very valuable, for a net profit, without even having to sell anything.
You've got this sort of cartoonish "DO AS I SAY OR I WILL CUT OFF THE WORLD'S UNOBTAINIUM" image of how this kind of economic power actually works. It sounds like a cartoon villain.
:mrgreen:
"WE BUILD FOR CHINA.... ONLY CHINA."
But two generators create a merged field?

That field would then be an ellipsoid- because it's being repulsed by the two generators, one at each focus.
Yes, but I thought we were talking of only one field. Sorry.
Solution: use an impact fuze, grenade goes off when it hits the shield. The grenade will be stopped by the screen just as sharply as it would be by a brick wall.
Humm.
Would robbing all of the grenade's momentum be considered a deceleration?
As I see it, the grenade promptly stops, the kinetic energy is conserved by being converted into internal molecular vibration (an insignificant amount of heat) at both the object and the generator, while the impact fuze won't feel a thing.
Solution: throw grenade, which stops and falls inside the shield in quite a lot of cases.
I'm counting on the soldiers to either be able to step sideways in half a second, or be immune to grenade explosions. Grenades launch shrapnel, which has very low armor penetration.
Solution: throw larger grenades.
You're making this difficult :(
But that's all specifics. Grenade spam might be very effective in some cases, and completely useless against others. It's one tactic amongst many and I haven't tweaked the setting enough to favor one method over the other.
Not denying it- point is that this is exactly the sort of thing that I think a good author would do to rein in the stereotypical REIGN OF THE SUPER-SWORDSMAN crap. You're the world's greatest swordsman... the enemy brings grenades. Shit.[/quote]

There's actually very little swordsmanship. If you read the little excerpt of tactics I'm thinking up of, you'll see that there's little sword vs sword swinging.
We could have phases of course. Suits might get uparmored ridiculously fast compared to handheld weapon power, requiring a drawn out sword duel culminating with a melee strike to a weakpoint, the gun becoming a secondary weapon. On the other hand, we could have, especially at the beginning, guns being much more powerful than armor, leading to merge/shoot first/win fights while dodging explosives.

madd0ct0r wrote:3m at MOST? are you sure that's what you meant? :lol:
Yes.
Field diameter is 3m. Joint two fields, and you are at most 3m from the opponent. With powerful legs, you can touch the opponent in 0.5 seconds. Either you hit and kill within that time, or the opponent has moved out of your line of fire and the melee engagement starts with guns on both sides.

At the current gun range distances (300-800m), it is too difficult to a land a large explosive on top of the field without the opponent detecting it in time using the onboard radar and moving out of the way/blasting it out of the sky.
Current ARENA system reaction times are 0.05 seconds, and they have 100 years to improve.

The only distance from which you can use a ranged weapon effectively is at ranges under 50m. At that distance, he can build up enough speed to force anything hitting him to react with the field, and halt. The halted object is now at zero velocity relative to the ground, while YOU are running past. Unless it has a timed detonator, or a sensor that detects you running past while it is inside the field, then you will survive. On one hand, the opponent can counter your rush by mining the field in front of you, but you have mine detectors and the ARENA system on your side.

Yes, I'm building up this setting to be antagonistic to ranged engagements. If all goes well, the optimal distance is 5m from the opponent. At this range, there is a vast plethora of things you can do with both shooting and meleee weapons, as well as tricks involving fields merging or closing.
and you know what they call low flying / jumping soldiers on a battlefield?

That sounds like a terribly effective weapon.
1) How does it stand up to being blasted by a stream of shrapnel?
2) How do you make it fast enough to reach the opponent, yet slow enough to not knock the opponent outside of the blastwave during the momentum transfer?
Yeah, its 4kg of explosives. You responded to the dilemma with BIGGER EXPLOSIONS. It just goes to show that infantry will not stand up to vehicle-grade weapons.

In this study, they tested against C4 explosives ranging from .227 to 0.567kg The suit weight required to protect the user from harm was 20-24kg. If the power armor has 300kg lift capacity available, how much explosive can it stand up to? Consider that the user would be fully enclosed (no overpressure damage) and armored (no fragmentation hits) so all that is needed is acceleration cushioning.
Simon_Jester wrote:And if the field gets slapped by a blast wave in midair, he lands sprawling as a turned turtle.
The blastwave will transfer momentum in a pretty predictable way, and if it explodes under you, then you'll be rocket jumping! :o

Also, if you land all sprawled out... well, the shield still works, no? It'll give you enough time to get up unless the opponent follows up with another rolling-past-the-field-lol grenade or merges for melee strike.

If you fail to get up, well, hats off to the opponent outplaying you completely.
Other such things like firehoses aren't really common battlefield weapons; they're just something to factor in because people familiar with how shielded armor acts in combat will try it. Regarding the idea of water 'stopping' against the firehose, I think you may overestimate the degree to which this matters. The momentum is still transferred; it's just that some of it is transferred through the (rapidly flowing aside) cushion of 'immobilized' water pinned between the hose jet and the screen.
And this is not a bad thing, because we need all the inventivity and wide range of weaponry and tactics we can get our hands on.

Unless the field is visibly affecting the surrounding material, then no, it is undetectable, since it does not affect radiation under most configurations. A much more interesting target is the huge amount of heat being pumped out by the generator.
That strikes me as rather odd and unlikely, but I'll take your word for it.
Plan B: chuck a grenade with an impact fuze instead of a timer.
Plan C: You have a millimeter radar and a quick-reaction onboard computer... a few onboard explosives and you've got yourself the walking equivalent of a TROPHY/ARENA system. It would be incredibly effective, considering that they only need to cover a miniature volume surrounding the user.
Image

On the downside, the suit would have silly-looking bricks like these all over the surface, allowing multiple launches in all directions of counter-explosive streams:
Image
This would hit diminishing returns pretty fast. Among other things, a tank has a fixed physical geometry- you know where to mount a given ERA brick to direct its blast against a rocket fired from 4 o'clock. A guy in power armor does not have this luxury, so the ERA bricks will often not be aligned optimally to deal with a threat (say, because the guy just raised his arm).

Also, the system is very expensive compared to the threat (grenade with impact fuse), and you have a very serious target discrimination problem because if the ERA triggers in response to thrown grenades, it will also trigger in response to thrown rocks, and to showers of debris in general.
Artillery is also effective at dumping cluster bomblets into an area (already common), or simply interdicting roads and such by physically damaging them so vehicles and troops can't pass (a major artillery mission). They also retain some deterrent value at keeping troops from staying in the open- even if the effective lethal blast radius is vastly reduced, that just means it isn't totally certain death to be caught out in the steel rain.
They'll retain their role as area denial, but at greater cost than today compared to their effectiveness. This might be compensated by the increased accuracy future technology would have ie. every shell is a guided missile.
Cluster bomblets are cheap, dumb shells are cheap. Also note that artillery is frequently used to wreck physical structures, including those which are probably not protected by shields.
I wonder however if any sort of artillery bombardment can render terrain impassable for foot infantry. If we go along the lines of shielded jeeps driving power armor around, then the troops can carry the jeep around any sort of terrain until they find something they can drive on again.
A suitable analogy would be SEALs troops carrying around their raft until they find water.
Men in power armor require better footing than men in shirtsleeves. Moreover, artillery will also be used to strike at targets other than the enemy infantry themslves, which are often not going to be shielded.
The main problem is that they're much bigger and unwieldier than a dagger- too much so to be a good backup weapon. There's a reason backup weapons are usually light, handy, and concealable things like daggers and pistols.
True, but you have to take into consideration the reach of your objects.
You are 3m from your opponent. If both of you raise your arms and point your weapons, then you will not touch other.

...whut.

I'm sorry, but this makes no damn sense. Can you please back up and explain exactly why you think gun kata is anything other than silliness here? Three meters is plenty of distance to riddle someone with bullets regardless of what hand to hand weapon they're carrying.

Also, how much practical experience do you have with hand to hand weaponry?

This requires so stupidly much coordination that it would best be done by an actual combat drone, not a human being with 100 ms reaction time.

Also, I love the image of some ULTIMATE GUN KATA WARRIAH who triumphs over enemy POWER ARMOR MOOKS this way, only to get slaughtered by a volley of grenades or a hail of antitank cluster bomblets.

Very true, but at the same time, you have to remember that this is 100 years in the future, and nothing forseeable is slowing down the progress of electronics and computer speeds/hardware power.
So? That suggests that air power takes the form of zillions of sneaky drones with bombs at the low end, hypersonic aircraft at the high end, and all manner of crazy in between.

Does the shield necessarily provide better protection than 10-20 tons of armor plate? Also, why are we removing the main gun? I liked the main gun, and it's got enough momentum transfer to be a credible antishield weapon.
I need something that both divides Asian geopolitics and sets up multiple conflicts around the surrounding zones.
This does not require an actual war, as noted. Ever heard of the Great Game?
Fighting a war with someone to make them sell you rocks at good prices is SUCH a stupid plan unless you plan to conquer them outright. There is no way in hell they'll make more favorable economic agreements after you bomb the crap out of them than before.

In which case India's demand is "lower your tariffs or I'll shoot this random guy, I swear to Vishnu I'll do it!" That's... incredibly dumb. As in, literally too stupid to be believed.

Read Clausewitz. War is an extension of politics by other means, an act of violence intended to compel an enemy to do your will. In this case, there is no foreseeable means by which the act of violence CAN actually compel the enemy to do India's will, so the whole thing makes no sense from their perspective.
This sounds like a Germany vs Russia to me.
Russia has the advantage when driving out German soldiers within its own territory, but to move onto the offensive, it suddenly has the longer, more vulnerable supply chain.
Worse. What it comes down to here is that BOTH sides are fighting through very difficult terrain (jungles and mountains and deserts), terrain where there just isn't much economic incentive to build much infrastructure. This is compared to the relatively dense infrastructure of Europe during World War Two.

Don't compare it to World War Two, compare it to itself. Think about what's going on here. Can either side realistically expect to fight the war in a way that will get them what they want? If not, then the war won't be fought at all.
Support structure, yes, but these things might also be the sort of nightmare drone people are scared of today: The stuff you airdrop over the battlefield, then let them kill all in sight until they break down or are destroyed. Chinese industry might find it more sustainable to rebuild the losses than to send a maintenance team 'over there' to recuperate and repair them. An infantry platoon can then wipe up the mess and disruption the drones caused, and do the detail work.
The problem then is that each drone is a million-dollar piece of hardware (kind of has to be, just to be functional), and you're writing them off for every kilometer of ground they may gain. You can't program them to march toward the enemy capital killing all in their path with any real effectiveness, unless you subject them to centralized control. This is because real armies need centralized control; they aren't just mindless mobs of berserkers wandering across the landscape. Mindless berserkers do not do very well when they run into fortified defenders.

You could potentially use them to clear a small fixed area of enemies, but the drones will then need to be stood down, recovered, and refurbished... and the territory thus cleared must be held by actual soldiers, which loops us right back to square one. You still can't fight without meaningful logistics.
[Groan]
Massive airlift only makes things worse, because the transport planes are hugely expensive and relatively easy to shoot down- they just plain can't carry that much.

It only makes sense if the Chinese grand strategy is being written by 15-year-old Internet morons who think "OMG SUPAR BADASS KILLBOT" and ignore how impractical it is to rely solely on such a weapon system to fight a serious war against a determined opponent in open terrain.
Aircraft with fields are pretty much immune to non-shielded missiles and weapons
A typical surface to air missile is more than large enough to carry its own shield generator onboard. They're as large or larger than a human being.
Then, missiles are build with fields on them, the air war is brought back to sanity, and the previous airlift strategy breaks down.
And anyone who knows shielded aircraft exist, and that this wonky shield-merge is possible, will have already designed shielded SAMs. Hell, people here thought of it in like 10-20 minutes of trying.
Except the Chinese have to be stupid enough to go on the strategic offensive by throwing money into a hole in the ground. What are they expecting to win here, anyway?

Even that may not actually help much. Countries like Afghanistan, Nepal, and Bangladesh aren't exactly huge lucrative markets. Access to the Middle East is best achieved by sea around Asia and not by land across Central Asia (as the Portuguese and everyone since has learned). Meanwhile, this whole war costs trillions and pointlessly antagonizes a nuclear-armed military power that is NOT going to somehow cease to exist even after their army is temporarily "crushed."
No no no its not hard embargo.
Let's stay with Uranium for now.
China forbids Kazakhistan from selling its U238 to the West. China buys ALL uranium production from regions within the pact, giving away in the process dollars. Then, it becomes the sole supplier of uranium to the rest of the world. If you want to buy uranium, you have to buy it from China, at Chinese prices with Chinese conditions. You can still buy as much as before, but it will cost you everything else.
Um... no? That's not going to work, because there's too much economic incentive for producers to defect, and it's practically impossible to somehow secure a world lock on all sources of Mineral X scattered across different continents.
You've got this sort of cartoonish "DO AS I SAY OR I WILL CUT OFF THE WORLD'S UNOBTAINIUM" image of how this kind of economic power actually works. It sounds like a cartoon villain.
:mrgreen:
"WE BUILD FOR CHINA.... ONLY CHINA."
The point is, it makes the Chinese into Big Scary Villains instead of a realistic country that operates to improve its own position. It's like, you needed an antagonist, so you remade China as the antagonist, even if that meant making them do completely unrealistic things like randomly invading Pakistan or threatening to cut off the world's uranium supply if they aren't given one... MILLION dollars or whatever.
Solution: use an impact fuze, grenade goes off when it hits the shield. The grenade will be stopped by the screen just as sharply as it would be by a brick wall.
Humm.
Would robbing all of the grenade's momentum be considered a deceleration?
As I see it, the grenade promptly stops, the kinetic energy is conserved by being converted into internal molecular vibration (an insignificant amount of heat) at both the object and the generator, while the impact fuze won't feel a thing.
For purposes of setting off an impact fuze, that will work quite nicely. Remember that the ONLY part of the grenade that is stopped is the part in contact with the field- which is exactly the same thing that happens when the grenade strikes a brick wall.
Solution: throw grenade, which stops and falls inside the shield in quite a lot of cases.
I'm counting on the soldiers to either be able to step sideways in half a second, or be immune to grenade explosions. Grenades launch shrapnel, which has very low armor penetration.
Shrapnel coming at you from an explosion at your feet is likely to penetrate armor designed to resist against specific weapons fired from specific angles. Also, counting on people sidestepping in half a second is... unwise. Sometimes they may not have room to dodge. Sometimes they won't see the grenade.
Solution: throw larger grenades.
You're making this difficult :(
That's what the enemy's grenadiers are trying to do. :D
There's actually very little swordsmanship. If you read the little excerpt of tactics I'm thinking up of, you'll see that there's little sword vs sword swinging.
It's not about swords as such, the point is that this sort of thing is exactly how you'd expect relatively mundanely equipped soldiers to respond to SHIELDED POWER ARMOR MAN WITH GUNSWORD AND SWORDGUN OMG BLACK BELT KATA HI-YAAA! or whatever.

Just some minor food for thought but the half-life for uranium-235 is 7*108 years and the half-life for U238 is 4.5*109 years, so as long as you don't use it for anything your uranium stock isn't gonna "spoil" in any signifigant way, meaning nukes cannot be completely written out by saying "X controls all the uranium production facilities"

Another possibility is to use gun-swords, as in barrels built into the blade.

I could do up a whole post and reply thing, but I don't see the point when I can just say this.

Even with shields making soldiers as tough as tanks, tanks are still better. You've shown how hard it can be to kill things at range with physical rounds and shown that even with shields a guy with a sword can still just run up and kill your soldier. A tank doesn't care how many times you swing your sword at it or poke it with a spear and can be armed with weapons that blow up people who try to mesh with it's shields and plant a bomb on it. Plus, given that these shields seem to be expensive, you need less of them to cover an army of tanks and APC's than you do to cover a bunch of combat cyborgs.

Thus in the end your setting actually calls for laser armed tanks fitted with laser ablating armor and not a return to melee combat. You would have seen this is you treated it as a case of armor out running the gun instead of trying to use shields as a means to get to melee combat.

I think it was mentioned before, but if a tank shoots a shielded soldier with a 120mm round, it's probably going to kill him just from sheer kinetic impact, when the shell rips the shield mountings off the suit and plows into his chest.

The thing that comes to mind most immediately is giant, shielded bulldozers that are sent plowing into your infantry lines, columns, whatever.

Unless you completely handwave the idea of shielded vehicles (and that would include walkers of osme kind) vehicles are still going to be better than shielded troops.

And I don't think you can completely handwave artillery, cuz artillery can get pretty big, and I don't think artillery munitions are, per round, all that expensive (a couple hundred per round for 155mm IIRC). Depending on how much your shielded supersoliders cost, you could probably easily afford to lob literally scores of such munitions at the targets and drown them in hundreds or thousands of kilos of explosive apiece. And if HE doesn't work, why not some sort of artillery shell that breaks up into flechettes or shot, or whatever prior to impact?

Also, even if the field protects them perfectly, they're going to be subjected to accelerations, and if the impact is hard enough the accelerations could be harmful if not lethal.


If someone is that gung-ho to have people fighting with melee weapons on a battlefield, you have to do alot more to constrain the enviroment they fight in. You might expect hand to hand more inside buildings and such than you would on an open battlefield.

I'm also not sure you could totally legislate lasers out of existence. There would be a demand for such weaponry (and masers) because they're obviously effective at bypassing shields, and they aren't as WMD-like as nukes (which have met with mixed success as far as 'controlling' that technology goes.)

There might be plenty of things you can do to limit their effectiveness on the battlefield. Adverse weather/enviromental conditions still affect them (moisture/fog/particulate matteR) so you might be able to attenuate them down as far as range and power (especially pulsed lasers as opposed to heat rays.) Use of some sort of carbon armor (with its good thermal characteritics, IIRC) could also be used to mitigate it. If lasers are also rather on the inefficient side of things (always possible to handwave) there might be drawbacks as far as useful lifespan (Components burn out/wear out perhaps), limited number of shots, cooling issues, and the like. You could even have a tradeoff.. pulsed lasers are more efficient, but because they rely on having a small focal point to do damage and becaues of all the factors acting against them you'd probably have to get fairly close for such weapons to be effective. Heat rays might be able to 'brute force' it (or masers), but they are energy intensive (but longer ranged) and even fewer shots/cooling issues (slower rate of fire.)

To complicate things even further, although you might not be able to restrict laser technologies totally, you might be able to regulate their usage in certain ways in a 'rules of war' manner. Restrict it to certain wavelengths (like near infrared, as opposed to visible or UV) due to hazards to civilians and human beings. Same with charged particle beams.

I also suspect you're not going to be able to get away with any sort of 'swung' weapon (at least nothing like a hammer or sword) in melee combat, as most weapons I remember being used in combat tended to be piercing/stabbing (especially in close packed formations.) I'd expect any melee weapons to be some analogue to a bayonet mounted on the forearm (you can't lose it or drop it.) And even then you'd probably have some sort of point flank firearm analogue worked into your arm mounts as well (some sort of shotgun/flechette for short range work once you got inside the shield.) some sort of directional grenade might be an issue too (if you can adhere them to your enemy, again under the shield.)

Most modern nuclear warheads are fission-fusion devices, which DO have a tritium component that spoils. But then, you don't need fresh uranium to produce more tritium.

true but unless I missed something all that was talked was control over worlds Uranium supply lines not it's Hydrogen-3 supply lines, but my point was that controlling uranium mines isn't gonna give you absolute control over the worlds nukes.

THought of this last night - take a standard rocket munition, mount it in a hollow cylinder longer and wider then the rocket is. The cylinder extends beyonds the rockets tip and is connected to the rocket with a reasonably brittle bond.
Fire it at a shield.
the front edge of the cylinder makes contact first, stops.
The edge is pushed through the wafer thin shield by the momentum of the rest of the casing behind it. We might be talking a few mm, but it's enough to penetrate.
THe shield dosen't like passing through solid objects. A neat hole is thus cut in the shield for the next second or two.
The deceleration of the cylinder reaches the clips holding it to the rocket. They break under the strain and the rocket continues under it's own momentum, through the hole.

I have this crazy idea that combat involves heavily shielded giant tracked vehicles (think of a Jawa sandcrawler lol) and the objective is to get your force within range of the enemy's lines (under their shields, close to their buildings, etc.) So you can deploy your troops and take and hold important facilities. The enemy might use artillery, laser-armed tanks or direct fire platforms (possibly unshielded - you could play up a tradeoff in that you could be shielded, or have a laser, but not both.) and contrive some sort of rock-paper scissors with defense (maybe vehicles have a specific anti-shield defense but they can't have that and the kinetic shielding on at the same time, so to protect against one you might have to expose yourself to the other.

There's also this peculiar idea where you might have two APC crawlers end up coming up alongside one another and one side boards the other like this was an Age of Sail naval action lol. Actually sort of like how shipboard combat happened in Lensman, I think.
