An entertaining movie!
But very unrealistic. Anyone who has driven a vehicle in AH knows vehicles can't drive through brush and push over trees! In the movie, a tank even drives through a log cabin. OMG! 
It was never meant to be a realistic movie, although there are some nice shots of T-34s in it. Its a metaphoric movie chock full of symbolism about evil and good and the nature of man.
The White Tiger is the Devil/Evil nature of man. The lead character is the man born again on the battlefield to lead the fight against evil. Remember when the lead character, the burned tank driver, said "every 30, 40, or 50 years the tanks talk to each other", or something to that effect? He was referring to how every 30 or so years Humanity finds enough reason to try and destroy itself and always has thru history, AND it will happen again. Again why the main character and his tank dissapear in smoke at the end of the movie.
All this is why the movie itself stayed on the same patch of ground even tho the Russian advance was "50 KMs a day". The Major was the conflicted one who was trying to find spirituality/God in that awful mess of a slaughter.
In short its the "Slaughterhouse Five" of tanks movies. The production values are quite high, the acting is excellent, there are some nice shots in the movie, and its definitely worth watching. But you cant look at it like a "Saving PVT Ryan". Its an allegory of the madness of war, the cruelty of men, the conflicts of faith, and the better angels of our nature that allow us to stand up to and defeat evil.
Even the very end is symbolic as the guy who started it all is making his case at the Altar of the Almighty.
