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).
Here is just the portion of the top Aces that I could capture in a screenshot. Hartmann at the top of the list was finally released from his Russian prison in 1955 after they imprisoned him on false charges.
