The correct title of this "movie" is Liar at the gate.

Rating: 1/10 (20 April 2020)

The correct genre of the film is not historical, but the sick fantasy of a madman.
In the film, the only truth is the battle of Stalingrad, Hero of the USSR Vasily Zaitsev and a German sniper.
The course of the battle of Stalingrad has been completely changed.
If you don't believe the Russian sources, then read the memoirs of German soldiers and officers.
