Uses

The M4 is the carbine version of the M16 assault rifle. It is especially favored by counter-terrorist and special forces units for close quarters combat because of its compactness and firepower. These features also make it useful for urban warfare. The M4 can be set to semi-automatic or three-round burst, while the M4A1 has the ability to go fully automatic.
