Being devils advocate here - how is that any different than the problem real bomber gunners faced in formation flying during WWII?
Real bomber gunners did not have AI drones which had AI gunners which auto fired when the the human controlled gunner shot.
The issue is this: When bombers are tight packed as they were historically, the AI bomber guns do not cease fire when friendly bombers are obstructing their line of sight. The Guns automatically fire when the human controlled gun fires on a clean shot.
So, while your shooting a Fw 190 on a clear shot from your lead bomber, your guns in bombers 2 and 3 are sometimes shooting into other bombers drones or lead ship. That's not realistic.
Right now, rear guns go safe when they pass along structures of the aircraft. It would be nice if AI guns on #2 and #3 bombers would do the same over friendly aircraft or drones.
