Battle rifleA battle rifle is a service rifle chambered to fire a fully powered cartridge. The term "battle rifle" is a retronym created largely out of a need to better differentiate the intermediate-powered assault rifles (e.g. the StG-44, AK-47, M16, AUG) from full-powered rifles (e.g. the FG-42, AVS-36, FN FAL, and M14, as well as the H&K G3 outside of sniping uses) as both classes of modern firearms have a similar appearance and share many of the same features such as detachable magazines, pistol grips, separate upper and lower receivers etc.
.30 CarbineThe .30 Carbine (7.62×33mm) is a rimless carbine/rifle cartridge used in the M1 carbine introduced in the 1940s. It is a light rifle round designed to be fired from the M1 carbine's 18-inch (458 mm) barrel. Shortly before World War II, the U.S. Army started a "light rifle" project to provide support personnel and rear area units a weapon with more firepower and accuracy than the standard issue M1911A1 .45 ACP handgun and half the weight of the standard issue M1 Garand .30-06 rifle or the .45 ACP Thompson submachine gun.
Blowback (firearms)Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel.
M1 GarandThe M1 Garand or M1 rifle is a semi-automatic rifle that was the service rifle of the U.S. Army during World War II and the Korean War. The rifle is chambered for the .30-06 Springfield cartridge and is named after its Canadian-American designer, John Garand. It was the first standard-issue autoloading rifle for the United States. By most accounts, the M1 rifle performed well. General George S. Patton called it "the greatest battle implement ever devised". The M1 replaced the bolt-action M1903 Springfield as the U.
M1 carbineThe M1 carbine (formally the United States Carbine, Caliber .30, M1) is a lightweight semi-automatic carbine that was issued in the U.S. military during World War II, the Korean War and the Vietnam War. The M1 carbine was produced in several variants and was widely used by paramilitary and police forces around the world after World War II. The M2 carbine is the selective-fire version of the M1 carbine, capable of firing in both semi-automatic and full-automatic. The M3 carbine was an M2 carbine with an active infrared scope system.
Gas-operated reloadingGas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action.
Stock (firearms)A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock, or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body.
M3 submachine gunThe M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to mass produce and lighter, at the expense of accuracy. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser," owing to its visual similarity to the mechanic's tool. The M3 was intended as a replacement for the Thompson, and began to enter frontline service in mid-1944.
StG 44The StG 44 (abbreviation of Sturmgewehr 44, "assault rifle 44") is a German assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44 (Maschinenpistole 43 and 44). The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H). The StG 44 was the first successful assault rifle, with features including an intermediate cartridge, controllable automatic fire, a more compact design than a battle rifle with a higher rate of fire, and being designed primarily for hitting targets within a few hundred metres.
Pistol gripOn a firearm or other tools, a pistol grip is a distinctly protruded handle underneath the main mechanism, to be held by the user's hand at a more vertical (and thus more ergonomic) angle, similar to the how one would hold a conventional pistol. In firearms, the pistol grip is located behind the trigger and generally held by the hand that operates the trigger. Rifles and shotguns without pistol grips are generally referred to as having "straight" or "upland" (shotguns only) style stocks.
