Bots do shoot as your gunners in planes, but my issue is not all of them and they seem to have far less firing range than enemy planes with the same caliber guns. Lots of planes have gunners on the belly of the plane or the sides, the bots manning these positions never fire, and on planes like JU 188 where your tail gunner that you can switch too, ( which is required almost because you will shoot way before any bots will. ) has a 13mm gun yet i have fighters with .50 cals shooting me way before i can hit them.
