U.S M249.SAW :
The M249 SAW (Squad Automatic Weapon),[4][5][6] formally written as Light Machine Gun, 5.56 mm, M249, is the US military’s adaptation of the Belgian FN Minimi, a light machine gun manufactured by FN Herstal (FN).
The M249 SAW is manufactured in the United States by the subsidiary FN Manufacturing LLC, a company in Columbia, South Carolina (FN America), 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 SAW provides infantry squads with a high rate of machine gun fire, combined with the accuracy and portability of a rifle.
The M249 SAW has seen action in major conflicts involving the United States since the U.S. invasion of Panama in 1989. In 2009, the United States Marine Corps selected the M27 Infantry Automatic Rifle to partially replace the M249 in USMC service.
In 2022, the U.S. Army selected the SIG Sauer XM250 to replace the M249 SAW.
