Two factions in Fuktupistan, Red and Blue, are searching for a chunk of plutonium called Black Ball. It's a small piece, but highly concentrated. Each side needs this final ingredient to build a nuclear device.
Each side has a bomb maker, who must remain at their HQ to complete the bomb, and a doctor who has pills (Tic Tacs or M&Ms) to cure anyone exposed to the Black Ball without the proper gloves/container. The doctor must remain in the village, but may move about freely in the village. The doctor is the only one who can treat people exposed to the Black Ball. He may also treat wounded, like a medic.
The US has sent in a Spec Ops force to retrieve the Black Ball as well. It's a very small force. (If the 501st Rangers will be at the game, they will be that force.)
The kicker: There is also a US operative (separate from the Spec Ops team) in the area operating clandestinely. He is the control for the Spec Ops team; they receive all of their intel from him at his base. He has maps of the AO and potassium iodine pills to make US forces immune to radiation sickness. He also knows the location of the Black Ball, but he can't get it himself because he's outnumbered. Both factions want him alive so they can the info from him.
Each faction must try and locate the US operative and extract the info of the location of the Black Ball, get the BB and take it to their bomb maker who will put it into their bomb and deliver their bomb to the other side's HQ and 'detonate' it, winning the game.
Good luck. IF you should capture the US operative, he will not co-operate without special measures. The leader of each faction will carry a dice. In order to get the information, the leader must roll a 6. There is one other way to get the BB: track the US team and ambush them when they retrieve the BB.
