Sturmgewehr-44 : Translates to "assault rifle" fielded by the Germans during WWII. The first select fire sub caliber rifle which is the technological predecessor of todays military rifles including the AK-47, FAL, and AR-15 type rifles.

A semiauto is NOT an assault rifle as it lacks a selector for full auto or burst fire. The name has been hijacked by anti-gun politicians to demonize popular rifles.
