T-34 76mm HE rounds are nerfed. Firing 26 rounds at a single AA gun, with no misses, had no effect that I could tell. Turning the hull gun on another AA emplacement took a mere 140 rounds to blow.
[edit]
Both of the T-34 76mm ammo types are nerfed vs structures. A single 37mm round from the M8, AP or HE, popped AA guns like daises. The T-34's AP and HE shot didn't do any visible damage to the AA guns or any other structures.
