Artillery is a class of heavy military ranged weapons built to launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word artillery referred to any group of soldiers primarily armed with some form of manufactured weapon or armor. Since the introduction of gunpowder and cannon, artillery has largely meant cannons, and in contemporary usage, usually refers to shell-firing guns, howitzers, mortars, and rocket artillery. In common speech, the word artillery is often used to refer to individual devices, along with their accessories and fittings, although these assemblages are more properly called equipment. However, there is no generally recognized generic term for a gun, howitzer, mortar, and so forth: the United States uses artillery piece, but most English-speaking armies use gun and mortar. The projectiles fired are typically either shot (if solid) or shell (if not solid). Historically, variants of solid shot including canister, chain shot and grapeshot were also used. Shell is a widely used generic term for a projectile, which is a component of munitions. By association, artillery may also refer to the arm of service that customarily operates such engines. In some armies, the artillery arm has operated field, coastal, anti-aircraft, and anti-tank artillery; in others these have been separate arms, with some nations coastal has been a naval or marine responsibility. In the 20th century, technology-based target acquisition devices (such as radar) and systems (such as sound ranging and flash spotting) emerged to acquire targets, primarily for artillery. These are usually operated by one or more of the artillery arms. The widespread adoption of indirect fire in the early 20th century introduced the need for specialist data for field artillery, notably survey and meteorological; in some armies, provision of these are the responsibility of the artillery arm. Artillery is arguably the most lethal form of land-based armament currently employed, and has been since at least the early Industrial Revolution. The majority of combat deaths in the Napoleonic Wars, World War I, and World War II were caused by artillery. In 1944, Joseph Stalin said in a speech that artillery was the God of War.
La artillería es el conjunto de armas de guerra pensadas para disparar proyectiles de gran tamaño a largas distancias empleando una carga explosiva como elemento impulsor. Por extensión se denomina así a la unidad militar que las maneja. Toda pieza artillera tiene una boca de fuego, un tubo metálico de determinado calibre y longitud y un armazón donde se apoya, denominado cureña o afuste.
