3. It can take OPFOR AI up to 5 seconds to turn around and if not for BLUFOR AI not checking the corners OPFOR AI would've been dead in 100% cases.
Do note that OPFOR AI is set to max skill. What should be happening is OPFOR AI turning around instantly at such setting - since for human players there are no such turn limits and even for a somewhat skilled player it wouldn't take even a half a second to turn around and face an enemy.
