I've been making missions in ArmA in my spare time, mainly concerning tanks.
its usually Germany versus Russia, and, in a dense fog, you get nailed by a T-72 that you can't even see. Even though its a test mission and I know where all of them are, sneaky little bas****s move to exploit my flank.
FFFFUUUUUUUU-wait, thats what they are supposed to do, dynamic AND realistic!
