The following is a list of World War II weapons of the United States, which includes firearm, artillery, vehicles, vessels, and other support equipment known to have been used by the United States Armed Forces—namely the United States Army, United States Army Air Forces, United States Marine Corps, United States Navy, and United States Coast Guard—as well as the Office of Strategic Services and other U.S. government agencies involved in the war, during American involvement between 1941 and 1945. This list includes experimental technology that, while created during the war, was never issued as intended.

---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
M1 Thompson submachine gun | Submachine gun | Close-quarters, personal security | Blowback, blish lock | United States | pplicker (firearms) Blowback, blish lock | Auto-Ordnance Company | .45 ACP | 150 | 700 | 1921 | 4.5-4.9 | 30-round magazine. | ||
M2 Hyde | Submachine gun | Close-quarters, personal security | Blowback, open bolt | United States | Marlin firearms company | .45 ACP | 570 | 1942 | 400 | 4.19 | Never issued or saw service. The M2 Hyde was the gap between the M1 Thompson and the M3 grease gun. It was designed to be lighter and cheaper to produce than the Thompson (since the Thompson was an extremely expensive weapon). It succeeded at both goals, but it was almost immediately replaced by the cheaper grease gun. Used 20-round or 30-round Thompson magazines. | |||
M3 and M3A1 submachine gun | Submachine gun | Close-quarters, personal security | Blowback, open bolt | United States | General Motors | .45 ACP | 91 | 450 | 1943 | 655363 | 3.61-3.70 | 30-round magazine. | ||
M50 Reising submachine gun | Submachine gun | Close-quarters, personal security | Blowback (Delayed blowback), closed bolt | United States | Harrington & Richardson | .45 ACP | 550 | 1941 | 2.8-3.1 | |||||
United Defense M42 | Submachine gun | Close-quarters, personal security | Blowback | United States | United Defense Supply Corp. | .45 ACP | 700 | 1942 | 15000 | 4.54 | 25-round box magazine (also issued with two 25-round magazines welded face-to-face) | |||
M55 Reising submachine gun | Submachine gun | Close-quarters, personal security | Blowback (Delayed blowback), closed bolt | United States | Harrington & Richardson | .45 ACP | 550 | 1941 | Identical to the M50 SMG except it sported a wire stock and had no compensator. It also had a slightly shorter barrel. The M50 and M55 served as the go-to SMGs before the Thompson. |

Heavy weapons platoon (HWP) is a term from military science which refers to an infantry platoon equipped with machine guns, mortars, rocket-propelled grenades, flamethrowers, grenade launchers, anti-tank weapons, or any other weapons that are portable but heavier than a single infantryman can reasonably transport and operate by themselves for combat, generally a crew-served weapon. Heavy weapons platoons are grouped into a weapons company or maneuver support company, which focuses on moving and using heavy weapons to support light infantry rifle companies armed with standard-issue small arms.

Shoulder-fired missile, shoulder-launched missile or man-portable missile, among other variants, are common slang terms to describe high-caliber shoulder-mounted weapons systems; that is, weapons firing large, heavy projectiles ("missiles"), typically using the backblast principle, which are small enough to be carried by a single person and fired while held on one's shoulder. The word "missile" in this context is used in its original broad sense of a heavy projectile, and encompasses all shells and rockets, guided or unguided. A more formal variant is simply shoulder-fired weapons system and the like.
The Vietnam War involved the People's Army of Vietnam (PAVN) or North Vietnamese Army (NVA), National Liberation Front for South Vietnam (NLF) or Viet Cong (VC), and the armed forces of the People's Liberation Army (PLA), Army of the Republic of Vietnam (ARVN), United States Armed Forces, Republic of Korea Armed Forces, Armed Forces of the Philippines, Royal Thai Armed Forces, Australian Defence Force, and New Zealand Defence Force, with a variety of irregular troops.
The 3-inch gun M1918 was a United States 3-inch anti-aircraft gun that entered service in 1918 and served until it was largely superseded by the 3-inch anti-aircraft gun M3 in 1930, though the M1918 remained with some National Guard units until early in World War II. The M3 was subsequently replaced by the M1 90mm AA gun early in World War II, primarily during 1942. The M3 3" gun was later adapted for the anti-tank role, serving as the main armament of the M10 tank destroyer during World War II.
The M18 recoilless rifle is a 57 mm shoulder-fired, anti-tank recoilless rifle that was used by the U.S. Army in World War II and the Korean War. Recoilless rifles are capable of firing artillery-type shells at reduced velocities comparable to those of standard cannon, but with greater accuracy than anti-tank weapons that used unguided rockets, and almost entirely without recoil. The M18 was a breech-loaded, single-shot, man-portable, crew-served weapon. It could be used in both anti-tank and anti-personnel roles. The weapon could be both shoulder fired or fired from a prone position. The T3 front grip doubled as an adjustable monopod and the two-piece padded T3 shoulder cradle could swing down and to the rear as a bipod for the gunner. The most stable firing position was from the tripod developed for the water-cooled Browning M1917 machine gun.
The Laotian Civil War was a military conflict that pitted the guerrilla forces of the Marxist-oriented Pathet Lao against the armed and security forces of the Kingdom of Laos, led by the conservative Royal Lao Government, between 1960 and 1975. Main combatants comprised:
The 3-inch anti-aircraft gun M3 was an American anti-aircraft gun which served throughout the 1930s and into early World War II. Developed from the earlier 3-inch M1917 and 3-inch M1918 guns, it was in the process of being replaced by the time of the US entry into World War II, but was subsequently adapted into an anti-tank gun role, both free-standing and in a self-propelled tank destroyer. It may have seen action in the Pacific Theatre.
