The top 200 posters on SB, the top 75 posters here on SD and anyone with military experience from either are sent to Middle Earth around TA 3000 (one year before the beginning of FOTR). The main war does not begin until TA 3018.
Assume, for a moment, that we do not immediately kill each other (except BigBryan and Laird).
Present there is a large-sized military base, with .50 cal machine guns and 40mm grenade launchers fixed in armored towers with vast ammo stores that cannot be removed. There are thick concrete walls and a trench, which is spanned by a drawbridge.
Inside are ample barracks and training facilities, a well-stocked medical clinic, a fully functional chemistry lab with supplies, a library of pertinent books, and 150 of the various unarmed versions of the Hummer (tanker, truck,).
Munitions are comprised of a massive supply of rations, uniforms, body armor, fuel, and the following ammo types: 9mm NATO, .40 S&W, 7.62mm NATO, and 5.56mmm NATO, as well as various 12ga shotgun shells.
All those teleported get to choose a pistol and a SMG, Pump-action shotgun, or rifle, but they have no ammo other than that listed above. People who are experienced with firearms may additionally bring a SAW or M60, as well as their personal weapons. They can carry one backpack each. They are automatically immunized to any middle-earth diseases, cured of any current infectious diseases, and know Westron fluently with decent Sindarin. Command is shared by IXJac and Painrack, as they actually have some military experience.
The objective: Neutralize Saruman's forces, and distract the forces of Mordor long enough for the Fellowship to sneak in. Any who completes this operation will recieve a doubled life expectancy (triple for the commanders), treasure, and the ability to return home if you desire.
What do you bring, and how well do we do?
