The M4 carbine is extensively used by the United States Armed Forces and is largely replacing the M16 rifle in United States Army and United States Marine Corps combat units as the primary infantry weapon. However, the USMC chose the full-sized M16A4 over the M4 as its standard infantry rifle. While ordinary riflemen in the USMC are armed with M16A4, M4 are used by troops in positions where a full-length rifle would be too bulky, including vehicle operators and fireteam and squad leaders.
