If we compare the photographs of Soviet and German tankers during the Second World War, then one striking difference will immediately catch the eye - the absence of protective headsets from the Panzerwaffe servicemen. Were they really not worn by German tank crews, or were they just shyly getting rid of an ugly piece of equipment before taking a photo?
A tanker's helmet is the most important piece of equipment that is needed in order to protect a person's head from impacts against metal elements of the tank structure. Without it, a tanker can be easily injured during a battle or vehicle movement. Why didn't the German tank crews wear them? Obviously, because the German command needs people with a broken brain, who, without a shadow of a doubt, will believe in the "sermon" of Joseph Goebbels about the superiority of the Aryan race. A joke, of course, albeit gloomy. In fact, everything was much more prosaic.
Equipment to protect the head of tankers was created in all countries of the world that had armored troops. It's just that each country had its own approach to this issue. The Soviet tank helmet appeared in 1931 and is still in use today. The French also created their own version of a helmet for tankers during the First World War. American tankers also had tank helmets.
But the British and Germans in this respect took a fundamentally different path. They did not make helmets for their tankers, but berets. The dense beret completely protected its head from unexpected blows, although it lost to helmets in the sense that it did not contain communication means built into the design. These berets were not simple, but with a soft lining and a small metal plate inside. By the way, the idea with a beret turned out to be useless, and therefore, after the Second World War, both the Germans and the British switched to helmets.
