1) I don't know about that, I'm not much of an OOB guy, tending to dance with the one what brung me.
2) Yes, within the scope of the game. Even the micros that are assigned on a plaoon level have 45 minutes or more (depending on the wind strength) of endurance. That is about 20 turns or so.
I don't think the micro UAV's are modeled, the one in the game seem to be the bigger, Predator type drones. They have an endurance of 24 hours or so.
3)I'm about to start trouble. I can hear the cries of 'gamey' already. I noticed that AH's with AAM's seem to do pretty good against them. I haven't really tested it, so that could have been an aberration. Man PADS do pretty good against them, or at least when I'm using them.
