The first two pics show GA against units both with two AA SUs. The Panzer division has a battalion and a company. The mot division has two battalions including the 'super' marine AA SU, Axis just have a couple of near this quality. As can be seen the first round of bombing takes out a lot of the AA, so that subsequent rounds of bombing are facing less or possibly no AA. This looks to be part of the game engine as almost invariably there are disproportionately high losses suffered by the AA elements.
The third pic shows the ground combat on the Panzer division after it has been hit by 14 GAs. It should have had a CV of 1-200, instead it has dropped to 14. This is the usual consequence of heavy GA, a lot of elements are damaged so the in combat CV will be much lower than the displayed value.
In this division there were 23 tanks lost to AA and then another 39 lost during ground combat, most of them because they were damaged by AA.
This is all WAD, there was fair amount of discussion about it a year or so ago during testing. However at that time fighter interception was working better.
I think this is something that has always been wrong in the way this aspect of the game functions. Massed GA is too effective and as Loki says unrealistic for the Soviets at this period of the war. The problem is exacerbated by fighter intercepts not working fully to the extent if the Soviet player takes advantage it is a game breaker.
