well its americans vs the canadians, just joking its US vs the bad terrorists (or guerilla whatsoever they are called "Enemy"). the wierd part is that you chose between def and assault teams and you are always US and the enemy is always terrorist while you appear as ter for your enemy.
and you probably wouldn't as its a military sim, a lot more realistic and has a CS style of gameplay where you can win by killing the enemy team as you dont respawn.
