well what if the last guy who killed the last AI ack was killed ITP?
Then you arrive on scene, see no tracers from the ack, wouldn't you calmly be flying around the field, waiting for a plane to vulch?
But not all the ack is down, some manable gun sites are still up, and someone is gunning in one of them, he would be firing and trying to zero in, seeing where his tracers go makes his life easier
Whereas you see no tracers and keep on flying around calmly
Suddenly, you hear a loud bang and your wing falls off
wouldn't you be pissed off when you figure out the guy was in a gun pos?
