The Russians and Nazis as allies invaded Poland together in 1939, so the Russians were obviously where they wanted to be for conquest.
The Russians can’t be trusted for any figures, but the bottom line is that they weren’t very good, they fight with masses of human meat.
I don’t know. My granddad was in air force. He wasn’t that much of an ace but still got three kills, of these two in one sortie. First time he shot Stuka and another time Bf-109 escort and when out of ammo rammed into He-111 bomber (though losing his aircraft in process too).
