So last night a buddy and I ended up jumping into a squad on one of the bigger more open maps. I forget the name of it so bear with me. As I'm picking Helis out of the sky I run dry on my Stinger. Well I decide, since we are playing Conquest, to just defend the point I'm at and deal with not having anymore rockets. Not even 2 minutes into defending I relize I have a chopper hovering over me. Not thinking I switch to my Stinger and lock on. Well just as I realize that I'm out of ammo, the pilot bails and the chopper comes tumbling down. Which now brings me to my ponit. Even if you don't have a rocket to launch at an enemy jet/chopper, lock on anyway and make them call your bluff. You might be suprised the next time you lock on to a chopper and then 2 seconds later you see an enemy come parachuting down. Must say I'm loving this game.
