Ok without digging for info and going by what I remember, which isn't very much lately. Battle of Kursk was 43, so definite PzIV G or H, Panther and no KT. The Tiger I was in service on the Eastern front and during the Kursk battle. Their were also PzIII 's still around including the Stug III.
As for the T-34, you might have had the later /76 and the /85. The 85 could knock out the Tigers on their flanks and rears, but not head on. Same situ for the Sherman. The rounds could penetrate the side armor of the Tiger I, vertical plates..but the KT had sloped armor like the Panther. So the best way to knock them out was from the rear, or of course the tracks.
Also to remember the Ferdinands were there as well. And another thing is that what is shown on the History channel is basically correct, except for some of the footage. They may show a KT, but it was from someplace else. I have DVD's that show N.Africa with the Germans using late war tanks on the russian plains or N. Italy. They use what footage they have to fill the space but it's not always correct. You'll also notice they use the same segments several times. just food for thought and help clear some things.
KT in the Bulge area is OK. It also doesn't have to be knocked out in any way...they always ran out of fuel in late 44 and especially in 45.
Whatever you do I am looking forward to seeing you build it.
