Editing Commandant (section)

==United Kingdom==
In the [[British Armed Forces]], a commandant is usually the [[commanding officer]] of a training establishment, such as the [[Royal Military Academy Sandhurst]] or the [[Royal Air Force College Cranwell]]. In  early 19th century  England, the term commandant was used  interchangeably with commandment - i.e., a person could act as  a Commandment of the Justices -  an officer-in-charge.<ref>{{cite book |last1=Rees |first1=A. |title=The Cyclopaedia; Or, Universal Dictionary of Arts, Sciences ... |date=1819 |page=16 |url=https://books.google.com/books?id=SkBRAAAAcAAJ&dq=he+acted+as++commandment+officer&pg=PA16 |access-date=7 October 2021 |quote=...in a Legal Sense, has various...a Commandment of the Justices,...or, when on their own authority...}}</ref>

Colonel-commandant was an appointment which existed in the [[British Army]] between 1922 and 1928, and in the [[Royal Marines]] from 1755 to some time after [[World War II]]. It replaced [[brigadier-general]] in the army, and was itself replaced by [[brigadier]] in both the army and the Marines. The colonel-commandant is also the ceremonial head of some Army corps and this position is usually held by a senior general.

Commandant was also the appointment, equivalent to [[Commodore (rank)|commodore]], held by the director of the [[Women's Royal Naval Service]] between 1951 and 1993.

In the [[Army Cadet Force]], a colonel is customarily the most senior commissioned officer in charge of an ACF county. This rank is thus known as the commandant and their second-in-command (2IC) is the deputy commandant, who has the rank of lieutenant colonel.

In the [[Royal Air Force Air Cadets]], the officer in charge of the organisation is given the title [[Commandant Air Cadets]] and holds the position for two years.

Formerly, commandant was the usual title for the head of the [[Special Constabulary]] within a police force. In some forces, the title was chief commandant, with subordinate divisional or sub-divisional commandants. The standard title for this position is now chief officer.

In the [[Voluntary Aid Organisation]] in [[World War I]], the chief officer of a military hospital or voluntary aid detachment (VAD), whether male or female, held the title of commandant.
