my teamran this really fun drill yesterday:
On one side of the field we had 2 players with guns. On break they run to the bunker of their choice and can not leave that bunker.
On the other side of the field are three players. Of these three players only one has a gun. This player follows the same rules as the two opposing players. The two unarmed players run the field dodging paintballs and communicating positions and fire direction to the one player with a gun. The object is to get both unarmed players to the 50 or further w/o getting hit.
