The Sturmgewehr MP-44
The Sturmgewehr was the result of a German intermediate cartridge development program that began in the mid-1930s. It was sidelined for a period as the focus of German Ordnance shifted to full-power rifles in 8x57mm with telescopic sights, but as the German fighting in Russia became more desperate, many Ordnance officers realized that the greater firepower offered by the Sturmgewehr concept was one of the few options that might be able to allow depleted German units to effectively hold ground against Russian attacks.
