Group captain is a senior commissioned rank in the Royal Air Force, where it originated,as well as the air forces of many countries that have historical British influence. It is sometimes used as the English translation of an equivalent rank in countries which have a non-British air force-specific rank structure. Group captain has a NATO rank code of OF-5, meaning that it ranks above wing commander, immediately below air commodore and is the equivalent of the naval rank of captain and the rank of colonel in other services.
It is usually abbreviated Gp Capt. In some air forces (such as the RAF, IAF and PAF), GPCAPT is used while in others (such as the RAAF and RNZAF) and sometimes, especially in historical contexts, as G/C. The rank of group captain is always the full phrase; it is never abbreviated as "captain".
On 1 April 1918, the newly created RAF adopted its officer rank titles from the British Army, with Royal Naval Air Service captains and Royal Flying Corps colonels becoming colonels in the RAF. In response to the proposal that the RAF should use its own rank titles, it was suggested that the RAF might use the Royal Navy's officer ranks, with the word "air" inserted before the naval rank title. For example, the rank that later became group captain would have been "air captain". Although the Admiralty objected to this simple modification of their rank titles, it was agreed that the RAF might base many of its officer rank titles on naval officer ranks with differing pre-modifying terms. It was also suggested that RAF colonels might be entitled "bannerets" or "leaders". However, the rank title based on the Navy rank was preferred and as RAF colonels typically commanded groups the rank title group captain was chosen. The rank of group captain was introduced in August 1919and has been used continuously since then.
Although in the early years of the RAF groups were normally commanded by group captains, by the mid-1920s they were usually commanded by an air officer.
In the post-World War II period the commander of an RAF flying station or a major ground training station has typically been a group captain. More recently, expeditionary air wings have also been commanded by group captains.
The rank insignia is based on the four gold bands of captains in the Royal Navy, comprising four narrow light blue bands over slightly wider black bands. This is worn on both the lower sleeves of the tunic or on the shoulders of the flying suit or the casual uniform. Group captains are the first rank in the RAF hierarchy to wear gold braid on the peak of their cap, informally known as 'scrambled egg'; however, they still wear the standard RAF officer's cap badge.
The command pennant for a group captain is similar to the one for a wing commander except that there is one broad red band in the centre. Only the wing commander and group captain command pennants are triangular in shape.
The rank of group captain is also used in a number of the air forces in the Commonwealth, including the Bangladesh Air Force, [ citation needed ] and the Trinidad and Tobago Air Guard. It is also used in the Egyptian Air Force, Hellenic Air Force, Royal Air Force of Oman, Royal Thai Air Force [ citation needed ] and the Air Force of Zimbabwe.Ghana Air Force, Indian Air Force (IAF), Namibian Air Force, Nigerian Air Force, Pakistan Air Force (PAF), Royal Australian Air Force (RAAF), Royal New Zealand Air Force (RNZAF), Sri Lankan Air Force
The Royal Canadian Air Force used the rank until the unification of the Canadian Forces in 1968, when army-type rank titles were adopted. A Canadian group captain then became a colonel. In official French Canadian usage, a group captain's rank title was colonel d'aviation. In the Argentine Air Force comodoro (commodore) is the rank in Argentine Spanish while in the Chilean Air Force, the rank in Chilean Spanish is coronel de aviacion or "colonel of aviation". Until 1973 it was used by the Royal Malaysian Air Force (RMAF), beyond that the sleeve insignia is that of a full colonel.[ citation needed ]
In addition to the equivalents used in most air forces, such as colonel, other air services, especially non-combat auxiliaries in Commonwealth countries, have used a variety of alternative names for equivalent ranks.
The equivalent rank in the Women's Auxiliary Air Force, Women's Auxiliary Australian Air Force, Women's Royal Air Force (until 1968) and Princess Mary's Royal Air Force Nursing Service (until 1980) was "group officer".
The equivalent rank in the Royal Observer Corps (until 1995) was "observer captain", which had a similar rank insignia.

Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States.
The Distinguished Flying Cross (DFC) is the third-level military decoration awarded to officers, and since 1993 to other ranks, of the United Kingdom's Royal Air Force and other services, and formerly to officers of other Commonwealth countries, for "an act or acts of valour, courage or devotion to duty whilst flying in active operations against the enemy".
Marshal of the Royal Air Force (MRAF) is the highest rank in the Royal Air Force (RAF). In peacetime it was granted to RAF officers in the appointment of Chief of the Defence Staff (CDS), and to retired Chiefs of the Air Staff (CAS), who were promoted to it on their last day of service. While surviving Marshals of the RAF retain the rank for life, the highest rank to which officers on active service are promoted is now air chief marshal. Although general promotions to Marshal of the Royal Air Force have been discontinued since the British defence cuts of the 1990s, further promotions to the rank may still be made in wartime, for members of the Royal Family and certain very senior RAF air officers in peacetime at the discretion of the monarch; all such promotions in peacetime are only honorary, however. In 2012, the then Prince of Wales was promoted to the rank in recognition of his support for his mother, Queen Elizabeth II, in her capacity as head of the armed forces (commander-in-chief), while in 2014 Lord Stirrup, who had served as Chief of the Air Staff and Chief of the Defence Staff for over seven years, was also promoted.
Flying officer is a junior commissioned rank in the Royal Air Force (RAF) and the air forces of many countries which have historical British influence. It is also sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. In these cases a flying officer usually ranks above pilot officer and immediately below flight lieutenant.
Squadron leader is a commissioned rank in the Royal Air Force and the air forces of many countries which have historical British influence. It is also sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure.
Wing commander is a senior commissioned rank in the British Royal Air Force and air forces of many countries which have historical British influence, including many Commonwealth countries but not including Canada and South Africa. It is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. It ranks immediately above squadron leader and immediately below group captain.
Air commodore is a one-star rank and is an air officer rank which originated in and continues to be used by the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence such as Zimbabwe, and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. The name of the rank is always the full phrase; it is never shortened to "commodore", which is a rank in various naval forces.
Air vice-marshal (AVM) is a two-star air officer rank which originated in and continues to be used by the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. Air vice-marshals may be addressed generically as "air marshal".
Air marshal is an air-officer rank which originated within the Royal Air Force. The rank is used by the air forces of many countries which have historical British influence, including many Commonwealth nations. The rank is usually equivalent to a vice admiral or a lieutenant general.
Flight lieutenant is a junior commissioned rank in air forces that use the Royal Air Force (RAF) system of ranks, especially in Commonwealth countries. It has a NATO rank code of OF-2. Flight lieutenant is abbreviated as Flt Lt in the Indian Air Force (IAF) and RAF, and as FLTLT in the Pakistan Air Force (PAF), Royal Australian Air Force (RAAF) and Royal New Zealand Air Force (RNZAF) and has sometimes also been abbreviated as F/L in many services; it has never been correctly abbreviated as "lieutenant". A flight lieutenant ranks above flying officer and below a squadron leader and is sometimes used as an English language translation of a similar rank in non-English-speaking countries.
Pilot officer is the lowest commissioned rank in the Royal Air Force and the air forces of many other Commonwealth countries. It ranks immediately below flying officer.
Officer Cadet is a rank held by military cadets during their training to become commissioned officers. In the United Kingdom, the rank is also used by members of University Royal Naval Units, University Officer Training Corps and University Air Squadron; however, these are not trainee officers with many not choosing a career in the armed forces.
Acting pilot officer is the lowest commissioned grade in the Royal Air Force. Acting pilot officer is not an actual military rank, therefore acting pilot officers are regraded to pilot officer instead of receiving a promotion. Unlike other RAF ranks which officers may hold in an acting capacity, acting pilot officer is maintained as a separate grade. The grade normally denotes an officer who has recently been commissioned and joined as a non-graduate direct entrant.
The officer ranks of the Royal Air Force, as they are today, were introduced in 1919. Prior to that Army ranks were used.
Before Unification as the Canadian Armed Forces in 1968, the Canadian military had three distinct services: the Royal Canadian Navy, the Royal Canadian Air Force, and the Canadian Army. All three services had a Regular (full-time) component and a reserve (part-time) component. The rank structure for these services were based on the services of the British military, the Royal Navy, the Royal Air Force, and the British Army. The change to a "Canadian" rank structure meant that many of the traditional (British) rank titles and insignia were removed or changed.
Major (Maj) is a military rank which is used by both the British Army and Royal Marines. The rank is superior to captain and subordinate to lieutenant colonel. The insignia for a major is a crown. The equivalent rank in the Royal Navy is lieutenant commander, and squadron leader in the Royal Air Force.
The rank structure of the Royal Australian Air Force (RAAF) has been inherited from the Royal Air Force (RAF). The RAF based its officer ranks on the Royal Navy, and its airmen ranks on the British Army.
The Royal Air Force uniform is the standardised military dress worn by members of the Royal Air Force. The predominant colours of Royal Air Force uniforms are blue-grey and Wedgwood blue. Many Commonwealth air forces' uniforms are also based on the RAF pattern, but with nationality shoulder flashes. The Royal Air Force Air Cadets wear similar uniforms.
Group Captain Desmond James Scott, was a New Zealand fighter pilot and flying ace of the Second World War. He was credited with the destruction of at least five enemy aircraft.
Captain (Capt) is a junior officer rank of the British Army and Royal Marines and in both services it ranks above lieutenant and below major with a NATO ranking code of OF-2. The rank is equivalent to a lieutenant in the Royal Navy and to a flight lieutenant in the Royal Air Force. The rank of captain in the Royal Navy is considerably more senior and the two ranks should not be confused.
