Organization
While navies are usually responsible for their own air defence, at least for ships at sea, organisational arrangements for land-based air defence vary between nations and over time.
The most extreme case was the Soviet Union, and this model may still be followed in some countries: it was a separate service, on a par with the navy or ground force. In the Soviet Union this was called Voyska PVO, and had both fighter aircraft and ground-based systems. This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces. Subsequently these became part of the air force and ground forces respectively
The divided responsibility echoed Germany's arrangements during the Second World War, where the Luftwaffe was responsible for air defence of Germany while the army protected itself. At the other extreme the United States Army has an Air Defense Artillery branch that provided ground-based air defence for both homeland and the army in the field. Many other nations also deploy an air-defence branch in the army.
In Britain and some other armies, the single artillery branch has been responsible for both home and overseas ground-based air defence, although there was divided responsibility with the Royal Navy for air defence of the British Isles in World War I. However, during the Second World War the RAF Regiment was formed to protect airfields everywhere, and this included light air defences. In the later decades of the Cold War this included the United States Air Force's operating bases in UK. However, all ground-based air defence was removed from Royal Air Force (RAF) jurisdiction in 2004. The British Army's Anti-Aircraft Command was disbanded in March 1955, but during the 1960s and 1970s the RAF's Fighter Command operated long-range air -defence missiles to protect key areas in the UK. During World War II the Royal Marines also provided air defence units; formally part of the mobile naval base defence organisation, they were handled as an integral part of the army-commanded ground based air defences.
The basic air defence unit is typically a battery with 2 to 12 guns or missile launchers and fire control elements. These batteries, particularly with guns, usually deploy in a small area, although batteries may be split; this is usual for some missile systems. SHORAD missile batteries often deploy across an area with individual launchers several kilometres apart. When MANPADS is operated by specialists, batteries may have several dozen teams deploying separately in small sections; self-propelled air defence guns may deploy in pairs.
Batteries are usually grouped into battalions or equivalent. In the field army a light gun or SHORAD battalion is often assigned to a manoeuvre division. Heavier guns and long-range missiles may be in air-defense brigades and come under corps or higher command. Homeland air defence may have a full military structure. For example the UK's Anti-Aircraft Command, commanded by a full British Army general was part of ADGB. At its peak in 1941–42 it comprised three AA corps with 12 AA divisions between them.

Famous quotes containing the word organization:
“In any great organization it is far, far safer to be wrong with the majority than to be right alone.”
—John Kenneth Galbraith (b. 1908)
“Democracy means the organization of society for the benefit and at the expense of everybody indiscriminately and not for the benefit of a privileged class.”
—George Bernard Shaw (1856–1950)
“I would wish that the women of our country could embrace ... [the responsibilities] of citizenship as peculiarly their own. If they could apply their higher sense of service and responsibility, their freshness of enthusiasm, their capacity for organization to this problem, it would become, as it should become, an issue of profound patriotism. The whole plane of political life would be lifted.”
—Herbert Hoover (1874–1964)
