Ha, well we have so many people, we treat this like real war. With more then 40 kids in my hood, its a lot of fun 20v20, there are always those people from other neighbor hoods to.
However, each team have one commander, they over see the troops and the squad leaders. Then each team have 4 squads, 1 leaders, 4 troops, usually.
Its loads of fun, to bad im only a troop :D
