Selective fireSelective fire, or select fire, is the capability of a weapon to be adjusted to fire in semi-automatic, fully automatic, and/or burst mode. The modes are chosen by means of a selector switch, which varies depending on the weapon's design. Some selective-fire weapons have burst fire mechanisms to limit the maximum number of shots fired automatically in this mode. The most common limits are two or three rounds per trigger pull. Fully automatic fire refers to the ability for a weapon to fire continuously until either the feeding mechanism is emptied or the trigger is released.
GlockGlock (stylized as GLOCK) is a brand of polymer-framed, short recoil-operated, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock Ges.m.b.H. The firearm entered Austrian military and police service by 1982 after becoming the top performer in reliability and safety tests. Glock pistols have become the company's most profitable line of products, and have been supplied to national armed forces, security agencies, and police forces in at least 48 countries.
BayonetA bayonet (from French baïonnette) is a knife, dagger, sword, or spike-shaped weapon designed to fit on the end of the muzzle of a rifle, carbine, musket or similar firearm, allowing it to be used as a spear-like weapon. From the early 17th to the early 20th century, it was a melee weapon used by infantry for offensive and/or defensive tactics. Today, it is considered an ancillary weapon or a weapon of last resort, although it is still used for ceremonial purposes.
Service rifleA service rifle or standard-issue rifle is a rifle a military issues to its personnel, typically to its regular infantry. In modern militaries, this is generally a versatile and rugged assault rifle, carbine, or battle rifle, suitable for use in nearly all environments and effective in most common combat situations. Most militaries also have service pistols that are issued as sidearms to accompany their service rifles. The term can also be used to describe weapons issued by non-military forces, such as police or paramilitaries.
Personal defense weaponPersonal defense weapons (PDWs) are a class of compact, magazine-fed, submachine gun-like firearms designed to fire rifle-like cartridges. Most PDWs fire a small-caliber (generally less than in diameter), high-velocity centerfire bottleneck cartridge resembling a scaled-down intermediate rifle cartridge, essentially making them an "in-between" hybrid between a submachine gun and a carbine.
Close-quarters combatClose-quarters combat (CQC) or close-quarters battle (CQB) is a close combat situation between multiple combatants involving ranged (typically firearm-based) or melee combat. It can occur between military units, law enforcement and criminal elements, and in other similar situations. In modern warfare, close-quarters combat usually consists of an engagement between two forces (typically "attackers" and "defenders") of varying size with small arms within a distance of up to 100 meters (110 yards), ranging from close-proximity shootouts to hand-to-hand combat.
Drum magazineA drum magazine is a type of high-capacity magazine for firearms. Cylindrical in shape (similar to a drum), drum magazines store rounds in a spiral around the center of the magazine, facing the direction of the barrel. Drum magazines are contrasted with more common box-type magazines, which have a lower capacity and store rounds flat. The capacity of drum magazines varies, but is generally between 50 and 100 rounds. In 1853, the first revolving drum magazine was patented by Charles N.
9×19mm ParabellumThe 9×19mm Parabellum (also known as the 9mm Parabellum or the 9mm Luger or simply as the 9mm) is a rimless, tapered firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, it is widely considered the most popular handgun and submachine gun cartridge due to its low cost and extensive availability. Since the cartridge was designed for the Luger semi-automatic pistol, it has been given the designation of 9mm Luger by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the Commission internationale permanente pour l'épreuve des armes à feu portatives (CIP).
Closed boltA semi or full-automatic firearm which is said to fire from a closed bolt is one where, when ready to fire, a round is in the chamber and the bolt and working parts are forward. When the trigger is pulled, the firing pin or striker fires the round; the action is cycled by the energy of the shot, sending the bolt to the rear, which extracts and ejects the empty cartridge case; and the bolt goes forward, feeding a fresh round from the magazine into the chamber, ready for the next shot.
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.
