I've been looking, in particular, at some of the Soviet P-39 aces and their scores. Although this is not particularly an area of expertise for me it seems highly suspect that many of them actually accrued the scores they claim. In one example, a regiment claimed 79 kills that were overwhelmingly fighters and in particuar Me 109's. What makes the claims interesting is that the Me 109E is the most claimed fighter and that the claims are being made in late 1942 early 1943. (I don't have the breakdown in front of me at the moment to give the unit and exact claims but it was a P-39 unit).
This tends to run counter to German, US, and British scores where most high scoring aces and units shot down far more bombers and other non-fighters than fighter aircraft. I suspect that the Soviet claims are highly inflated. Any commentary on this or sources that can accurately verify these claims?
