6- In a team of 10 players, 2 helis are a max. More apache/orcas are useless, unless for the mood (Oooooo yes i love seeing a 5 aicrafts squad, this make me feel in "apocalypse now" ). By the way, don't expect to become MVP if are in a heli during all the game.

I only wish poeple listened to this very very good rule; but since the helicopters are new and people are learning with them, nobody will listen to it

As for hummers, they have the same weakness ass all vehicles; they cannot shoot stright up. Just get above it and waste it with your guns because, unlike groun units, you *can* shoot straight down.
