During World War II, Sherman tank commanders often wore a distinctive uniform that included a combination of standard military clothing and specific tank crew gear. The most recognizable item was the tankers' jacket, which was typically a short, heavy cotton or wool jacket with a belted waist. This was often accompanied by a pair of combat trousers and a standard helmet or a tank beret, depending on the specific role and regulations.
In terms of headgear, tank commanders sometimes wore a black tankers’ cap or a helmet designed for armored vehicle crews, which often had ear protection and a chin strap.
Overall, the uniform was practical, designed to provide warmth and protection while allowing for ease of movement in the confined space of a tank.
