Unit History: Aviation Squadron

An air force, army aviation or naval aviation squadron typically consists of three or four flights, with a total of 12 to 24 aircraft, depending on aircraft type and air force. In the Imperial Japanese Army in the Second World War, three air squadrons were assigned to each air regiment. Some air forces (including the Royal Air Force and United States Air Force) also use the term for air force ground units. Multiple squadrons (typically three to ten) make up a wing. An escadron is the equivalent unit in France’s Armee de l’Air (with an as a subsection of an escadron) and Canada’s air force.
In the Air Training Corps of the UK, a Squadron is a group of cadets who parade regularly.
 
In the Civil Air Patrol, a squadron is the basic administrative unit.
