WW2 was a horrific time period for the USSR. You are not going to find many movies glorifying the war and the violence within it.
Soviet cinema shied away from that type of jingoism because it felt shallow and meaningless.
The point that Soviet films were focusing on wasn’t that “Soviet soldiers rolling over the Germans in spectacular breathtaking scenes of patriotic fervor”, it was that the war was a horrifying, depressing, and terrible time, and that by the heart of the nation surviving, that was testament enough to the strength of the USSR.
Poor driver. Just tell him to take the bus.
