Christ allmighty!! This looks like heavy battles from Cross of Iron movie! You can feel the fear and panic as soviet horde is getting closer.. If you show this to german veteran he would probably have flashbacks..
Excellent, love the delayed brew up tank. What Russian tank at 3:30 ? Oh ... KV-85. Maybe if the graphic requirement is too much to show a tank shell being loaded into an anti-tank gun, I'd just make a guy standing next to the breech holding a shell and not moving. Nice StuG III with 75mm StuK 40 L/48.
Oh, I forgot (!) -- tanks running over dead soldiers. Just like 'Fury,' which may have ripped it off from 'Cross of Iron.' Live guys getting run over ....
