I'd like to talk about the Bofors gun.
Why does an anti-air (!) fortified position is absolutely incapable of bringing planes down? I've conducted some tests with 40 Bofors positions (it's 400 out of 100 deployment points, even 4x4 games cannot be seen with such amounts of Bofors) and all those were not able to bring down a single reconnaissance plane, while a single OKW AA position does the trick with no effort.
I think the Bofors position is ought to receive a buff in this regard.
