The two main variations of paintball are "air ball" where you play in a field with inflated bunkers set the same on both sides and "woodsball" where you play in the woods. Air Ball is a very fast paced, high intensity game that the military guys don't have much of an advantage because it's mostly strategy, aggression and gun skills that win games. Most teams that play together often have a huge advantage.You'd think a school that had a huge ROTC presence would do well - a bunch of marine sharpshooters on their team. Future Green Beret's or something!
