That's my point, that Tiger I in the techblog is awesome, but it's not in the film, the IS-2 based is the only one seen. The Pz IV wreck on the train was nice, but the one in battle was inaccurate, but it only appears as a whole for a few seconds.

Bastshoe, I'll look for that book in English. I've read Vassily Grossman and enjoyed his work as well as the translation of Zaitsev's memoirs.
