In the early 1990s, the U.S. Army and Marine Corps introduced a new weapon designed to radically boost the firepower of infantry squads. The M249 squad automatic weapon, or SAW, fired the same ammunition as the M16A2 rifle at a rapid rate of fire and was more compact than the gun it replaced. Although controversial, the M249 still serves today in the U.S. Army and U.S special operations forces worldwide.
