The M249 light machine gun (LMG), also known as the M249 Squad Automatic Weapon (SAW),^[3][4] which continues to be the manufacturer's designation,^[5] and formally written as Light Machine Gun, 5.56 mm, M249, is the American adaptation of the Belgian FN Minimi, a light machine gun manufactured by the Belgian company FN Herstal (FN).

The M249 is manufactured in the United States by the subsidiary FN Manufacturing LLC, a company in Columbia, South Carolina, and is widely used in the U.S. Armed Forces. The weapon was introduced in 1984 after being judged most effective (compared to a number of candidate weapons) to address the lack of automatic firepower in small units. The M249 provides infantry squads with a high rate of machine gun fire, combined with the accuracy and portability of a rifle.

The M249 is gas operated and air-cooled, it has a quick-change barrel (allowing the gunner to rapidly replace an overheated or jammed barrel), a folding bipod attached to the front of the gun (an M192 LGM tripod also being available). 

M249s have seen action in major conflicts involving the United States since the U.S. invasion of Panama in 1989. In 2009, the U. S. Marine Corps selected the M27 Infantry Automatic Rifle, to partially replace the M249 in USMC service.^[6] In 2022, the U.S. Army selected the Sig Sauer XM250 to replace the M249.

Rate of fire: Approx. 800 rounds/min
