Marine Corps Weapons
The M1911A1 pistol
The M1911 is a single-action, semi-automatic, magazine-fed, recoil-operated pistol chambered for the .45 ACP cartridge, which served as the standard-issue sidearm for the United States Armed Forces from 1911 to 1985. It was first used in later stages of the Philippine-American War, and was widely used in World War I, World War II, the Korean War, and the Vietnam War. The M1911 is still carried by some U.S. forces. Its formal designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original Model of 1911 or Automatic Pistol, Caliber .45, M1911A1 for the M1911A1, adopted in 1924. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam era.
The development of the M16A2 rifle was originally requested by the United States Marine Corps as a result of the USMC's combat experience in Vietnam with the XM16E1 and M16A1. The Marines were the first branch of the U.S. Armed Forces to adopt the M16A2 in the early/mid 1980s with the United States Army following suit in the late 1980s. Modifications to the M16A2 were extensive. In addition to the new rifling, the barrel was made with a greater thickness in front of the front sight post to resist bending in the field and to allow a longer period of sustained fire without overheating. The rest of the barrel was maintained at the original thickness to enable the M203 grenade launcher to be attached.
The M4 carbine is a family of firearms tracing its lineage back to earlier carbine versions of the M16, all based on the original AR-15 designed by Eugene Stoner and made by ArmaLite. It is a shorter and lighter version of the M16A2 assault rifle, with 80% parts commonality. The M4 has selective fire options including semi-automatic and three-round burst (like the M16A2), while the M4A1 has a "full auto" option in place of the three-round burst.
The M240, officially Machine Gun, 7.62mm, M240, is the US military designation for the FN FN MAG (Mitrailleuse d`Appui Général, "General Purpose Machine Gun"), a family of belt-fed, gas-operated medium machine guns firing the 7.62x51mm NATO cartridge.
The M240 has been used by the United States armed forces since the mid 1980s. It is used extensively by infantry, as well as ground vehicles, watercraft, and aircraft. Despite not being the lightest medium machine gun in service, the M240 is highly regarded for reliability, and its standardization among NATO members is also seen as a major advantage.
Squad Advanced Marksman Rifle
The Squad Advanced Marksman Rifle (SAM-R) is a semi-automatic rifle developed by and in service with the United States Marine Corps. It gives Marines the capability to provide precision fire in support of the rifle squad, providing precision fire in support of an assault, and aid in observation and adjusting of supporting arms.
The M40 is a bolt-action sniper rifle used by the United States Marine Corps. It has had four variants — the M40, M40A1, M40A3, and M40A5. The M40 was introduced in 1966. The changeover to the A1 model was completed in the 1970s, the A3 in the 2000s, and the A5 in 2009.
Each M40 is built from a Remington 700 bolt-action rifle, and is modified by USMC 2112 (Armorers) at Marine Corps Base Quantico, using components from a number of suppliers. New M40A3s are being built, and A1s are upgraded to A3s as they rotate into the armory for service and repair. The rifles have had many sub-variations in telescopic sights, and smaller user modifications. The M40A5 will incorporate a detachable magazine and a threaded barrel to allow for the use of a sound suppressor or other muzzle device.
The M82 (also sometimes designated by the military as the M107) is a recoil-operated, semi-automatic anti-materiel rifle developed by the American Barrett Firearms Manufacturing. A heavy SASR (Special Application Scoped Rifle), it is used by many units and armies around the world. It is also called the "Light Fifty" for its .50 caliber BMG (12.7 mm) chambering. The weapon is found in two variants—the original M82A1 (and A3) and the bullpup M82A2. The M82A2 is no longer manufactured, though the XM500 can be seen as its successor, in that it also employs a bullpup configuration.
The latest derivative of the M82 family is the M82A1M rifle, adopted by U.S. Marine Corps as the M82A3 SASR and bought in large numbers. This rifle differs from M82A1 in that it has a full length Picatinny rail that allows a wide variety of scopes and sighting devices to be mounted on the rifle. Other changes are the addition of a rear monopod, slightly lightened mechanism, and detachable bipod and muzzle brake.
Squad Automatic Weapon
A squad automatic weapon (SAW, also known as section automatic weapon or light support weapon) is a weapon designed to give infantry squads or sections a compact and mobile source of suppressive fire. SAWs are usually equipped with a bipod for stabilization and fire the same cartridge as the assault rifles carried by other members of the unit. This reduces logistical requirements by making it necessary to supply only one type of ammunition to a unit. SAWs are light enough to be carried by one man, as opposed to heavy machine guns such as the Browning M2, which fire more powerful cartridges but require a crew to operate at full effectiveness.
M2 Browning Machine Gun
The M2 Machine Gun, Browning .50 Caliber Machine Gun, is a heavy machine gun designed towards the end of World War I by John Browning. It is very similar in design to John Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses the larger and more powerful .50 BMG cartridge, which was named for the gun itself (BMG standing for Browning Machine Gun). In service the gun was nicknamed Ma Deuce by U.S. Military personnel or simply "fifty-cal." in reference to its caliber. The design has had many specific designations; the official designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly-armored vehicles and boats, light fortifications, and low-flying aircraft.
MK19 Grenade Launcher
The Mk 19 Grenade Launcher is an 40 mm belt-fed automatic grenade launcher or grenade machine gun that entered U.S. military service during the Cold War, first seeing action during the Vietnam War and remaining in service today.
The BGM-71 TOW is an anti-tank guided missile. "TOW" stands for "Tube-launched, Optically-tracked, Wire data link, guided missile". The TOW was first produced in 1970 and is one of the two most widely used anti-tank guided missiles in the world. The
