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.

To this end, the guns were issued primarily in the East, with whole companies being equipped in order to focus a maximum amount of firepower, rather than spreading the new rifles piecemeal across all units. Ultimately, of course, this was insufficient to prevent the growing Soviet advance - but for the individual German soldier, an MP-43/44/StG-44 would have been a much more comforting weapon than a Kar98k Mauser!
