Grenade launcher

A grenade launcher is a weapon that fires a specially designed, large-caliber projectile, often with an explosive, smoke, or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces. Grenade launchers are produced in the form of standalone weapons (either single-shot or repeating) or as attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 are mounted on tripods or vehicles. Some armored fighting vehicles also mount fixed arrays of short-range, single-shot grenade launchers as a means of defense. The earliest devices that could be referred to as grenade launchers were slings, which could be used to throw early grenado fuse bombs. The ancestors of modern ballistic grenade launchers, however, were simplistic muzzle-loading devices using a stake-like body to mount a short, large-bore gun barrel into which an explosive or incendiary device could be inserted; these were later refined into shoulder-fired blunderbuss-like firearms referred to as "hand mortars". These weapons were not highly regarded due to their unreliability, requiring the user to ignite a fuse on the projectile before firing, and with a substantial risk of the explosive failing to leave the barrel; attempts to ignite the fuse on firing using the gunpowder charge resulted in weapons that would often force the fuse into the grenade and make it explode in the barrel. During the First World War, several novel crew-served launchers designed to increase the range of infantry hand grenades were developed, such as the Sauterelle crossbow, the West spring gun, and the Leach trench catapult devices. None were particularly effective, and such devices were ultimately replaced by light mortar systems such as the Stokes mortar, while the task of increasing the range of infantry explosive projectiles was primarily taken by rifle grenades.

Grenade
A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, an arming safety secured by a transport safety.
Rifle grenade
A rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade were thrown by hand. The practice of projecting grenades with rifle-mounted launchers was first widely used during World War I and World War II and continues to the present, with the term "rifle grenade" now encompassing many different types of payloads including high explosive, fragmentation, anti-tank warheads, concussion, smoke, incendiary, and flare missiles.
Ranged weapon
A ranged weapon is any weapon that can engage targets beyond hand-to-hand distance, i.e. at distances greater than the physical reach of the user holding the weapon itself. The act of using such a weapon is also known as shooting. It is sometimes also called projectile weapon or missile weapon because it typically works by launching solid projectiles ("missiles"), though technically a fluid-projector (which throws out pressurized streams of liquid or even gas) and a directed-energy weapon (which does not involve any tangible projectile) are also ranged weapons.
