Squadron (military unit)

A squadron was historically a cavalry sub-unit, a company-sized military formation. The term is still used to refer to modern cavalry units but can also be used as a designation for other arms and services. In some countries, such as Italy, the battalion-level cavalry unit is called a "Squadron Group".

In the British Army and many other Commonwealth armies, a squadron is the Royal Armoured Corps counterpart of an infantry company or artillery battery. A squadron is a sub-unit of a battalion-sized formation (usually a regiment), and is usually made up of two or more troops. The designation is also used for company-sized units in the Special Air Service, Special Reconnaissance Regiment, Honourable Artillery Company, Royal Engineers, Royal Corps of Signals, Royal Army Medical Corps, Royal Marine Commandos and Royal Logistic Corps and in the defunct Royal Corps of Transport.

Squadrons are commonly designated using letters or numbers (e.g. No. 1 Squadron or A Squadron). In some British Army units it is a tradition for squadrons to also be named after an important historical battle in which the regiment has taken part. For example, the Royal Armoured Corps Training Regiment assigns trainees to "Waterloo" Squadron, named in honour of the significance the cavalry played in the Allied forces' victory over Napoleon. In some special cases, squadrons can also be named after a unique honour which has been bestowed on the unit.
