Weapons Used

The basic infantry weapon of the United States Marine Corps is the M16 assault rifle family, with a majority of Marines being equipped with the M16A4 service rifle, or more recently the M4 carbine—a compact variant. Suppressive fire is provided by the M249 SAW, which is being replaced by the M27 Infantry Automatic Rifle, and the M240G machine gun, at the squad and company levels respectively. In addition, indirect fire is provided by the M203 grenade launcher in fireteams, M224 60 mm mortar in companies, and M252 81 mm mortar in battalions. The M2 .50 caliber heavy machine gun and MK19 automatic grenade launcher (40 mm) are available for use by dismounted infantry, though they are more commonly vehicle-mounted. Precision fire is provided by the M39 Enhanced Marksman Rifle, which is being replaced by the M110 Semi-Automatic Sniper System, and M40A3 and A5 sniper rifle,and the M24 bolt action sniper rifle.

The Marine Corps uses a variety of direct-fire rockets and missiles to provide infantry with an offensive and defensive anti-armor capability. The SMAW and AT4 are unguided rockets that can destroy armor and fixed defenses (e.g. bunkers) at ranges up to 500 meters. The Predator SRAW, FGM-148 Javelin and BGM-71 TOW are anti-tank guided missiles; all three can utilize top-attack profiles to avoid heavy frontal armor. The Predator is a short-range fire-and-forget weapon; the Javelin and TOW are heavier missiles effective past 2,000 meters that give infantry an offensive capability against armor.

Marines are capable of deploying non-lethal weaponry as the situation dictates. Part of a Marine Expeditionary Unit earning the Special Operations Capable designator requires a company-sized unit capable of riot control.

Some older weapons are used for ceremonial purposes, such as the Silent Drill Platoon's M1 Garands, or the use of the M101 howitzer for gun salutes.
