I will write in advance so that no one has any questions. Yes, the picture is of the Soviet army, not the German army. The soldiers are wearing an [SSh-36](https://en.wikipedia.org/wiki/SSh-36) helmet, which was widely used at the time. [SSh-40](https://en.wikipedia.org/wiki/SSh-39_and_SSh-40) helmet, which is more commonly known, was made in 1940 (thanks, Captain Hindsight). Immediately after the opening of the Eastern Front in WWII, these helmets began to be replaced because of the "sail effect" and poor visibility. And also because they looked like the German ones, yes.
