A German panzer crewman stands over the grave of two fallen panzer crewmen – potentially from the Panzer I in the background.
Most likely this photo is taken in 1941 during Operation Barbarossa, as the black panzer beret – the schutzmütze – was phased out and production had ceased in 1941, however it continued to be worn after that date for a while. The surviving crewman is wearing the newer style of panzer crew headgear which was introduced in early 1940.
