Erich Hartmann DID NOT fight the whole war. Not even close. He came to the front in october 1942 and as of mid 1943 he only a couple of kills.
So the vast vast vast majority of 352 kills came in the last two yaers of the war when the soviets regained their strenght with better pilots, planes, tactics and of courve vast numbers.
Or how abour willi batz who got an even later start in 1943...
Willi” Batz flew 445 combat missions in scoring his 237 victories. 233 victories were achieved over the Eastern front but he did claim four victories, including two four-engined bombers over the Western front. He was wounded three times and was shot down four times.
Bf109G may not have had best performance but it was the grestest fighter of all time!!
