German Soldiers in WW2 were the main fighting force of the Heer. The Wehrmacht, or Nazi Germany's armed forces, had many divisions and specializations of soldiers who fought for Hitler's Reich. Panzer crewmen were required to operate tanks on the battlefield. A tank usually consisted of 3-5 people, depending on the class of the tank. Famous tanks like the Tiger I and Panzer IV would need at least 4 people to operate fully. Loaders like this one were required to repair the tanks and load the ammunition for the main gun.
