History
Developed by German Army ordnance despite Hitler's explicit opposition to intermediate cartridges. The project was concealed from Hitler by labeling the weapon 'MP44' (Maschinenpistole) to avoid his scrutiny. After Eastern Front officers reported its effectiveness, Hitler reversed course and renamed it Sturmgewehr 44. Soviet engineers captured StG44s and the concept heavily influenced Mikhail Kalashnikov's AK-47 and 7.62x39mm development.
