I cant see where this is going the above point is a very valid one & as stated the AA capability is to give it some means of last ditch defence not for sweeping the skys. Given the fact its WW2 the chances of it actualy hitting anything are virtualy zero so if its sitting still in woods like it should the jigs up its given its self away. Okay if your winning & using it for moping up its lost that ability & remote chance of hitting something, but its probably moving so wont fire anyway. The only time I could see as useful is if you are using as cannon fodder to save more expensive stuff but then you are arguing for a correct gun mount & using the unit unrealisticly.
Lets face it in WW2 game air is a great inteligence gatherer I may fly a plane over with weapons off so it can find its targets for the next pass & its just said over here. Once you enter the radar controled/SAM era of MBT this is however a very unheallthy tactic hence stand off attacks become the best form of attack & little inteligence is gathered.
