Why is it that when I am in a German Plane it is like I am getting hit by ground fire even over my own base, but when I am in an Allied Plane I do not have that same situation. Thank You Ketinkrad
It doesn't actually have anything to do with what plane your flying. The only countries the game cares about are Bishop, Knight, and Rook. A couple things could have happened to cause the ack to hit you;
1: The base was captured - when a base is captured all the ack immediately respawns and begins firing. Any of the base's former owners who are near the field will probably be hit.
2: Bad luck - as others in the thread of mentioned friendly ack will not target you, but it WILL damage you if it does hit you while attempting to shoot down an enemy plane that is within range. I've been caught by ack a few times while taking off at the same time an enemy aircraft is buzzing the field.
