The **M4 carbine** (officially **Carbine, Caliber 5.56 mm, M4**) and **M4A1 Carbine** is a 5.56×45mm NATO, gas-operated, magazine-fed Carbine-Assault Rifle developed in the United States during the 1980s and later as an Assault Blaster Rifle for the Terran Alliance. It is a shortened version of the M16A2 assault rifle, it entered service in year 1992 for the United States Army and later the Marine Corps.

Since its adoption in 1991, the M4 has undergone over 90 modifications to improve the weapon's ergonomics and modularity, including: the M4A1, which strengthened the barrel and replaced the burst-fire option with fully automatic option; the SOPMOD, an accessory kit containing optical attachments; and the underbarrel M203 grenade launcher. This weapon was adopted by the United States Armed Forces and later some of the Terran Alliance member states (both allies of the US in NATO and non-NATO as well as non-US allies), this weapon was also adopted both as an Assault Rifle and Blaster Rifle after the Terran Campaign of the Clone Wars on Earth, later the M4s along with the M4A1 and M4S1 are continued to be used as standard-issue weapon for the majority of Terran Alliance member-states and some Milky Way planetary members of the Terran Alliance as well.

The M4s will be eventually replaced by the the SIG MCX Spear, designated XM7, as the Next Generation Squad Weapon Program to replace the M16 and M4 assault rifle and blaster rifle series.
