The US Army launched the CAR-15 Commando in 1966 and called it the "Machine Gun, 5.56 mm, XM177E1". After user feedback and suggestions, the XM177E1 has been improved. In 1967 the US Army purchased it for the Military Assistance Command, Vietnam-Studies and Observations Group (MACV-SOG) in the new CAR-15 assault variant and called it XM177E2.
