The M82, standardized by the US Military as the M107, is a recoil-operated, semi-automatic anti-materiel rifle developed by the American Barrett Firearms Manufacturing company. The first working rifles were available in 1982.

The M1 Garand (officially designated as United States Rifle, Caliber .30) is a semi-automatic rifle chambered for the .30-06 Springfield rifle cartridge. It was the first standard-issue semi-automatic rifle.

M14 rifle, officially the United States Rifle, 7.62 mm, M14, is an American selective fire automatic rifle that fires 7.62×51mm NATO (.308 Winchester) ammunition. It gradually replaced the M1 Garand in US Army service by 1961 and in US Marine Corps service by 1965.

The M16 fires the 5.56×45mm NATO cartridge. The rifle entered United States Army service and was deployed for jungle warfare operations in South Vietnam in 1963, becoming the U.S. military's standard service rifle of the Vietnam War by 1969, replacing the M14 rifle in that role.

The M1911 is a single-action, semi-automatic, magazine-fed, recoil-operated pistol chambered for the .45 ACP cartridge,[1] which served as the standard-issue sidearm for the United States Armed Forces from 1911 to 1985.

The M249 is manufactured in the United States by the local subsidiary FN Manufacturing LLC in South Carolina and is widely used in the U.S. Armed Forces. The weapon was introduced in 1984 after being judged the most effective of a number of candidate weapons to address the lack of automatic firepower in small units.

The Beretta M9, officially the Pistol, Semiautomatic, 9mm, M9, is a 9×19mm Parabellum pistol adopted by the United States Armed Forces in 1985.
