Group (military unit)

A group is a military unit or a military formation that is most often associated with military aviation. The terms group and wing differ significantly from one country to another, as well as between different branches of a national defence force. Air groups vary considerably in size and status, but generally take two forms: A unit of two to four squadrons, commanded by a lieutenant colonel, colonel, commander, naval captain or an equivalent rank. The United States Air Force (USAF), groupes of the French Armée de l'air, gruppen of the German Luftwaffe, United States Marine Corps Aviation, British Fleet Air Arm and some other naval air services usually follow this pattern. A larger formation, often comprising more than 10 squadrons, commanded by a major general, brigadier general, commodore, rear admiral, air commodore or air vice-marshal. The air forces of many Commonwealth countries, such as the British Royal Air Force (RAF), follow this pattern. In such cases, the group is equivalent to a US wing, a German Geschwader or a French escadron. During the early stages of World War I in France and Germany, the respective aviation services formed groupes and Gruppen. Beneath the level of the group was a unit of six to 16 aircraft: an escadrille or Staffel. Immediately above the French and German groups was the escadron or Geschwader. In the Royal Flying Corps (RFC) and Royal Naval Air Service (RNAS), a squadron was usually composed of 18–24 aircraft. When the Royal Air Force (RAF) was formed in 1918 from a merger of the RFC and RNAS, an officer with the rank of colonel typically commanded a group. The following year, when the RAF introduced its own rank system, RAF colonels became group captains, reflecting both the level of command responsibility and the seniority of naval captains (the equivalent Royal Navy rank). By World War II, the groupes of the French Armée de l'Air usually comprised two escadrilles (but sometimes only one, or as many as four). French groupes were the equivalent of U.S. Army Air Corps (USAAC) / U.

Air force

An air force – in the broadest sense – is the national military branch that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army aviation or naval aviation units. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces often in the form of aerial reconnaissance and close air support.

Military organization

Military organization or military organisation is the structuring of the armed forces of a state so as to offer such military capability as a national defense policy may require. In some countries paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as insurgent forces, often mimic military organizations, or use these structures, while formal military organization tends to use hierarchical forms.

Wing (military unit)

In military aviation, a wing is a unit of command. In most military aviation services, a wing is a relatively large formation of planes. In Commonwealth countries a wing usually comprises three squadrons, with several wings forming a group (around 10 squadrons). Each squadron will contain around 20 planes. On its establishment in 1912, the British Royal Flying Corps (RFC) was intended to be an inter-service, combined force of the British Army and Royal Navy.
