'Commander' is a
military rank which is also sometimes used as a military title depending on the individual customs of a given military service. Commander is also used as a rank or title in some organizations outside of the military, particularly in police and law enforcement.
Commander as a military rank
Commander is a
military rank used in many
navies and some
air forces but is very rarely used as a rank in
armies. The rank (originally "Master and Commander") originated in the 18th and early 19th centuries to describe lieutenants that were "captains" of smaller ships such as sloops or brigs. The Royal Navy shortened "Master and Commander" to just "Commander" in 1794.

Royal Navy

Insignia of a Royal Navy Commander
A commander in the British
Royal Navy is above the rank of
lieutenant-commander, below the rank of
captain, and is equivalent in rank to a
lieutenant colonel in the army. A commander may command a
frigate,
destroyer,
submarine, aviation squadron or shore installation, or may serve on a staff.
Royal Australian Navy
A Commander in the
Royal Australian Navy (RAN) is identical in description to a Commander in the British
Royal Navy. RAN Chaplains who are Division 1, 2 and 3 (of 5 divisions) have the equivalent rank standing of Commanders but do not wear this rank on their uniform.
Royal Air Force
Since the British
Royal Air Force's middle-ranking officers' designations are modelled after the
Royal Navy's, the term
wing commander is used as a rank and is equivalent to a lieutenant colonel in the army or commander in the navy. The rank is above
Squadron Leader and below
Group Captain.
In the now defunct
Royal Naval Air Service, which amalgamated with the
Royal Flying Corps to form the Royal Air Force in
1918, pilots held appointments as well as their normal Royal Navy ranks, and wore insignia appropriate to the appointment instead of the rank. Flight commander wore a star above a lieutenant's two rank stripes, squadron commander wore two stars above two rank stripes (less than eight years' seniority) or two-and-a-half rank stripes (over eight years seniority), and wing commander wore three rank stripes. The rank stripes had the usual Royal Navy curl, and were surmounted by an eagle.
United States Navy

Historically, the rank of "Commander" was originally called "Master Commandant" in the United States Navy. This rank corresponded in function to "Master and Commander" in the Royal Navy. It was later changed in 1838 to its modern form.

Commander as a military title
British Army
In the
British Army, the term "commander" is officially applied to the
non-commissioned officer in charge of a
section (section commander), vehicle (vehicle commander) or gun (gun commander), to the
subaltern or
captain commanding a
platoon (platoon commander), or to the
brigadier commanding a
brigade (brigade commander). Other officers commanding units are usually referred to as the
Officer Commanding (OC),
Commanding Officer (CO),
General Officer Commanding (GOC), or
General Officer Commanding-in-Chief (GOC-C), depending on rank and position, although the term "commander" may be applied to them informally.
United States Army
In the
United States Army, the term "commander" is officially applied to the
commanding officer of army units; hence, there are
company commanders,
battalion commanders,
brigade commanders, and so forth. At the highest levels of
U.S. military command structure, "commander" also refers to what used to be called
commander-in-chief, or CINC, until
October 24,
2002, although the term CINC is still used in casual speech.
United States Air Force
In the
Air Force, the term "flight commander" (abbreviated "FC") is officially applied to the commanding officer of an Air Force unit; hence, there are squadron commanders, group commanders, wing commanders, and so forth. In rank, a
squadron commander is typically a
Major or
Lieutenant Colonel, a
group commander is typically a
Colonel, and a
wing commander is typically a senior Colonel or a
Brigadier General.
Commander as a non-military rank or title
British police rank
Commander is also a senior
police rank in the two
London police forces, the
City of London Police, and the
Metropolitan Police Service. It is senior to
Chief Superintendent in both forces and junior to
Deputy Assistant Commissioner in the Metropolitan Police and
Assistant Commissioner in the City of London Police. It equates to
Assistant Chief Constable in other forces. The Metropolitan Police introduced the rank in
1946, when they split the rank of Deputy Assistant Commissioner (with senior DACs keeping that rank title and junior DACs being regraded as Commanders). The Metropolitan Police also had a rank of
Deputy Commander, ranking just below Commander, between 1946 and
1968. In addition, officers in charge of policing each of
London's boroughs are given the title of "Borough Commander", although they hold the rank of
Chief Superintendent, not Commander.
United States police rank
The
Los Angeles Police Department is one of the few American police departments which use this rank. A Commander in the LAPD is equivalent to an
Inspector in other US departments (such as the
NYPD); the LAPD rank was originally called Inspector as well, but was changed in
1974 to Commander after senior officers voiced a preference for the more
military-sounding rank.
Commander is also utilized by larger
Sheriff's Departments in the United States. The rank usually falls between Chief Deputy and Captain, which is three positions removed from the sheriff.
The
Washington, DC Metropolitan Police Department (
MPDC) also uses the rank of Commander. The rank falls between those of Inspector and Assistant Chief.
The Rochester, NY Police Department (RPD) uses the rank of Commander. Higher than Captain and below Deputy Chief, the rank is achieved by appointment. Commander is the rank held by the two patrol division heads and other Commanders fill various administrative roles. The St. Paul Police Department (MN) is another police force that uses the rank of commander. In the St. Paul Police department, Commanders serve as the chief of the district/unit that they oversee.
Many police departments in the midwest (exception being the
Chicago Police Department) use the rank of commander. It is equivalent to a lieutenant in most other departments, being above a sergeant and below a deputy chief or captain.
Commander is also used as a title in certain circumstances, such as the Commander of a squad of Detectives, who would usually be of the rank of Lieutenant.
Military and Chivalric Orders
The title of Commander is used in the Military Orders, such as the
Sovereign Military Order of Malta, for a member senior to a
Knight. The title of Knight Commander is often used to denote an even higher rank. These conventions are also used by most of the continental orders of chivalry. The United Kingdom uses different classifications.
In most of the British Orders of Knighthood, the grade of Knight (or Dame) Commander is the lowest grade of knighthood, but is above the grade of Companion (which does not carry a knighthood). In the
Royal Victorian Order and the
Order of the British Empire, the grade of Commander is senior to the grade of Lieutenant or Officer respectively, but junior to that of Knight or Dame Commander. In the British
Order of St. John, a Commander ranks below a Knight. (However, Knights of the Order of St. John are not called "Sir.")
In common usage
"Commander" may sometimes be used by laymen, usually applied to the person who is accountable for and holds authority over a group or the attempts of a group to achieve a common goal.
