Dury the July tour, here's the kill breakdown by tank:
Panzer IV H: 60989 kills
Sherman: 44005 kills (3:1 kill ratio against the Panzer, 8:1 ratio against T34)
Tiger: 13053 kills (4:1 kill ratio against the Panzer, 1.1:1 against the Sherman, 15:1 against the T34)
T34: 6000 kills (of which I accounted for 5% ;-) )
M8: 4399 kills
Most of those Panzer kills were against other Panzers.
What's really funny is to look at the T34 kills and see how many were against aircraft. It's nearly half of the T34's total kills. Especially the B25h, the 110, and the IL-2. This is because the T34 is such a great base-assault tank, and is really good at destroying aircraft trying to take off. It's also good at shooting down B25s, 110s, and IL-2s in the air with its tank gun while they dive in on it. ;-)
Anyhow, I'm happy that the majority of the kills are still happening in the Panzer. I won't mind seeing the T34/85 climb up there on the kill chart and compete with the Sherman and the Panzer, but I'd be sad to see the Panzer drop down to where the T34/76 is today. A little perkage on the T34/85 might well keep it at around the same level as the Sherman. That would be great.
