The Anti Air guns can be so badass if used right :D With those you DEFINITELY have to follow ahead of them while they fly, but I've taken out so many people with them. You'll love them to death when a warhawk attempts to weed your holdout while in stealth (can't lock on with the missiles) :D ESP great for taking out tanks and jeeps as well. Just watch out for the goddamn binocs -_-;
And yeah, the people with rockets on the ground can kiss my ass xD They make it an absolute bitch to enter hover mode ><
