It would be fine if the AT gun (Zis 2 or 3) did has a stealth ability, as a upgrade, for exemple...P.
I have a suggestion pop up when I played EF todayIt is possible to put the KV-2 as the reward unit rather than SU-122?we know KV-1/KV-85 are the reward units of the T-34s so if KV-2 become reward unit of Su-122 (which use t-34 chassis )we can than choose between using T-34 chassis tank (as standard unit) and the KVs (as reward unit) thenthought?
