Brigadier general (Brig. Gen.) or brigade general is a senior rank in the armed forces. It is the lowest ranking general officer in some countries, usually sitting between the ranks of colonel and major general. When appointed to a field command, a brigadier general is typically in command of a brigade consisting of around 4,000 troops (four battalions). In some countries a brigadier general is informally designated as a one-star general (OF-6).

In some countries, this rank is given the name of brigadier, which is usually equivalent to brigadier general in the armies of nations that use the rank.

The rank can be traced back to the militaries of Europe where a "brigadier general", or simply a "brigadier", would command a brigade in the field. The rank name général de brigade (which translates as "brigade general") was first used in the French revolutionary armies.

In the first quarter of the 20th century, British and Commonwealth armies used the rank of brigadier general as a temporary appointment, or as an honorary appointment on retirement; in the 1920s this practice changed to the use of brigadier, which was not classed as a general officer.

Some armies, such as Taiwan and Japan, use major general as the equivalent of brigadier general (See also Japan & Taiwan for details.). Some of these armies then use the rank of colonel general to make four general-officer ranks.

Mexico uses the ranks of both General brigadier and General de brigada.

This gallery displays Air Force brigadier general insignia if they are different from the Army brigadier general insignia. (They usually are.) Note that in many Commonwealth countries, the equivalent air force rank is Air Commodore (and in the Netherlands, it is simply Commodore).

The rank of brigadier general (with some local variations) is used in the Argentine Air Force. Unlike other armed forces of the World, the rank of brigadier general is actually the highest rank in the Air Force. This is due to the use of the rank of brigadier and its derivatives to designate all general officers in the Air Force: brigadier (lowest general officer); brigadier-major (middle); and brigadier-general (highest). The rank of brigadier general is reserved for the Chief General Staff of the Air Force, as well as the Chief of the Joint General Staff if he should be an Air Force officer.

The Argentine Army does not use the rank of brigadier-general, instead using brigade general (Spanish: General de brigada) which in turn is the lowest general officer before Divisional General (Spanish: General de Division) and Lieutenant General (Spanish: Teniente General).

In the Australian Imperial Force during World War I, the rank of brigadier general was always temporary and held only while the officer was posted to a particular task, typically the command of a brigade. When posted elsewhere, the rank would be relinquished and the former rank resumed. This policy prevented an accumulation of high-ranking general officers brought about by the relatively high turnover of brigade commanders. Brigadier general was also used as an honorary rank on retirement. The rank insignia was like that of the current major general, but without the star/pip^[2].

As in the United Kingdom, the rank was later replaced by brigadier. Hence, prior to 1922, a brigadier general was a general officer; subsequently, brigadiers were not generals, which is shown by the rank insignia being like that of a colonel, but with an extra (third) star/pip^[2].

Prior to 2001, the Bangladesh Army rank was known as brigadier, in conformity with the rank structure of the Commonwealth Nations. In 2001 the Bangladesh Army introduced the rank of brigadier general, however "the grade stayed equivalent to brigadier", and although classified as a "one-star rank", a brigadier general is not considered to be a general officer – the lowest ranking general officer is Major General. Brigadier general is equivalent to commodore of the Bangladesh Navy and air commodore of the Bangladesh Air Force. It is still more popularly called brigadier.

The Belgian Army uses the rank of général de brigade (French) and brigadegeneraal (Dutch) (Brigade General). However, in this small military there are no permanent promotions to this rank, and it is only awarded as a temporary promotion to a full colonel who assumes a post requiring the rank, notably in an international context (e.g. as Military Attaché in a major embassy).

General de brigada (Brigade general) is the lowest rank amongst general officers of the Brazilian Army – i.e. like in most British Commonwealth counties, the lowest general officer rank is a two-star rank, and a General de Brigada wears a two-star insignia. Hence, it is equivalent to the major general rank of many counties. In the Brazilian Air Force, all of the senior ranks include "Brigadeiro" – the two-star rank is Brigadeiro (Brigadier), the three-star rank is Major-Brigadeiro (Major-Brigadier) and the four-star rank is Tenente-Brigadeiro-do-Ar (Lieutenant-Air-Brigadier). (See Military ranks of Brazil and Brigadier#Latin America for more information.)

The rank of brigadier general is known in Burma as bo hmu gyoke and is often the deputy commander of one of Burma's Regional Military Commands, commander of the light infantry division (LID) or Military Operation Commands. In civil service, a brigadier general often holds the office of deputy minister or director general of certain ministries.

In the Canadian Forces, the rank of brigadier-general (BGen) (brigadier-général or bgén in French) is a rank for members who wear army or air force uniform, equal to a commodore for those in navy uniform. A brigadier-general is the lowest rank of general officer. A brigadier-general is senior to a colonel or naval captain, and junior to a major-general or rear admiral.

The rank title brigadier-general is still used notwithstanding that brigades in the army are now commanded by colonels. Until the late 1990s brigades were commanded by brigadier-generals. In the air force context, brigadier-generals used to command air force groups until these bodies were abolished in the late 1990s.

The rank insignia for a brigadier-general on air force uniforms is a single wide braid on the cuff, as well as a single silver maple leaf beneath crossed sabre and baton, all surmounted by St. Edward's Crown, worn on the shoulder straps of the service dress jacket, and on slip-ons on other uniforms. The rank insignia on army uniforms is a gold maple leaf beneath crossed sword and baton, all surmounted by St. Edward's Crown, on the shoulder straps. On the visor of the service cap are two rows of gold oak leaves; the air force wedge cap features silver braid on the edges of the ear flaps. The cap insignia for a general officer is a modified version of the Canadian Forces insignia. Army brigadier-generals wear gorget patches on the collar of the service uniform tunic.

Brigadier-generals are initially addressed verbally as "General" and name; thereafter by subordinates as "Sir" or "Ma'am" in English or mon général in French. They are normally entitled to staff cars.

Note: Until unification in 1968 of the Royal Canadian Air Force, Canadian Army, and the Royal Canadian Navy, rank structure and insignia followed the British pattern. This system of rank insignia was reinstated in 2014. In army usage, the term "brigadier" was used to denote what is now known as a brigadier-general while the air force used the rank of air commodore.

Chinese rank of (Da-Xiao 大校) or Senior Colonel is a direct equivalent of a brigadier. It ranks above colonel (Shang-Xiao 上校) and below major general (Shao-Jiang 少将). A brigadier is commonly in command of a division (Shi 师) or a brigade (Lv 旅). Divisional commanders are seldom general officers.It is also called Briggu General. Briggu is an ancient village.

The rank of brigadier general is the first general officer rank in the Fuerzas Militares,^[3] and the National Police.^[4]

Denmark, a NATO member, has for many years been following NATO standards and adapting its rank system to closely relate. As in the armies of most other NATO nations, brigadier general is the lowest of the general ranks, usually a brigade commander.

In the Estonian military, the rank is called Brigaadikindral.

France uses the rank of "brigade general" (général de brigade). The rank contrasts with the French sub-officer rank of brigadier. As with all French general officers, a French brigade general is titled "general" without any implication that he is an army general; for instance General Charles de Gaulle never rose higher than brigade general.

Until 1793, the rank of brigadier des armées ("brigadier of the armies") existed in the French Army, which could be described as a senior colonel or junior brigade commander. The normal brigade command rank was maréchal de camp (literally "field marshal", which in other militaries is a more senior rank). When rank insignia were introduced, brigadier des armées wore one star and a maréchal de camp wore two stars. During the French Revolution, the revolutionaries' drive to rationalise the state led to a change in the system of ranks. The rank of brigadier des armées was abolished and the normal brigade command rank, maréchal de camp, was replaced by brigade general. The rank of brigade general inherited the two stars of the rank of maréchal de camp, explaining the absence since 1793 of a French rank with only one star.

Nowadays, a French général de brigade generally commands a brigade, which currently is the biggest permanent formation in the French Army. The rank can also be awarded in an honorary fashion to retiring colonels. The insignia are two stars, worn on the shoulder or at the sleeve of the uniform, depending on the order of dress. Two different kepis are issued : the service kepi sports the two stars, while the formal kepi features a large band of oak leaves (the kepi of a division general has two smaller such bands).

Charles de Gaulle held the rank of brigade general. He was given a temporary promotion to this rank in May 1940 as commander of the 4th Armoured Reserve Division (4e division cuirassée de réserve). However his initial authority as head of the Free French really came from being the only cabinet member (Under-Secretary of State for National Defence and War) outside occupied France, not from his military rank. As a reminder of his war position, he refused any further promotion.

The equivalent modern German OF6-rank is Brigadegeneral. The concept of a brigadier general rank is relatively new, as prior to 1945 the lowest German general officer OF6-rank was Generalmajor, which was often considered equivalent to brigadier general in other armies.

In Hungary the brigadier general is a relatively new military rank used from 1992. The army and the air force insignia are not different.

The equivalent rank for brigadier general in the Iranian army and air force is called sar-tip. In Persian the word tip means brigade, and sar means head or commander. After 1987 the rank sar-tip dovom (second brigadier general) was introduced between sar-tip and sar-hang (colonel or literally head of regiment). There is no equivalent for sar-tip dovom in other countries. The rank above sar-tip is sar-lashgar. Lashgar means division so, sar-lashgar means divisional general (major general).

The Iranian Revolutionary Guards also use this rank; the difference is in salutation. One refers an army or air force brigadier general as "amir sar-tip", while a revolutionary guard general is referred to as "sardar sar-tip".

The only branch not using those two ranks is the Iranian Navy. Instead the equivalents are Daryādār and Daryādār Do for the higher and lower rank, respectively, usually translated as Rear Admiral and Rear Admiral 2 (or Flotilla Admiral).

The country is divided into two areas for administrative and operational reasons, and in each area there is an infantry brigade. The two brigade group structure envisages distinct operational areas of responsibility for each of the brigades and is supported in its responsibilities by the Naval Service and Air Corps. Each of the brigade formations and the Air Corps is commanded by a brigadier general, while the Naval Service is commanded by a commodore.

In the Israel Defense Forces, the rank of brigadier general is called tat aluf and is the third highest rank, below aluf (major general) and rav aluf (lieutenant general or general), and above aluf mishne (colonel).

In the Italian Armed Forces the rank has different denominations. In the Army, the rank for combat arms officers is generale di brigata whilst for the logistics and technical corps is called brigadier generale. The rank is also present in the other armed forces, police corps and other services of Italy, with different denominations, and it is associated with the lowest level within the government top management.

Because no brigadier general rank is used in the army of some countries such as Japan and Taiwan, major general is rank of brigade commander. For this reason, French are represented in the manner as Général de brigade and some countries, such as Brazil and Chile, follow it also words of some countries of the Italian and Spanish, and the like. In that sense, such as Japan and Taiwan use major general as the equivalent of brigadier general. In both countries, there was a movement to create a brigadier general rank in accordance with the rank system of general officer in many countries, but now it has disappeared.

In the Jordanian military, the rank of brigadier general is known as amid (عميد), and it is higher than colonel (akeed عقيد) and lower than major general (liwa لواء).

Prior to 2002, the Polish rank of generał brygady was equivalent to both the ranks of major general and brigadier general.

In the Portuguese Army and Air Force, brigadeiro-general is a temporary general rank for the colonels that have to exercise a special command. It is the equivalent of the commodore rank in the Portuguese Navy.

The rank was reintroduced in 1999. Before that, simply as brigadeiro, it existed from 1707 to 1864 and again from 1929 to 1947, not being considered a general rank. From 1947 to 1999, brigadeiro become the two-star general rank in the Portuguese Army. As two-star rank, it was substituted by the rank of major-general in 1999.

In the Romanian Army the general de brigadă is the lowest rank of general officers, The equivalent in the Navy is contra-amiral and in the Air-Force general de flotilă aeriană.

The rank of brigadier general is known in South Korea as junjang (Korean: 준장; hanja: 准將)^[5] and is a direct equivalent to the United States one-star rank, with very similar insignia. The military of North Korea does not technically maintain a brigadier general rank, but the rank of senior colonel (대좌, taejwa) which is above colonel (상좌, sangjwa) and below major general (소장, Sojang) is an effective equivalent.

In the Spanish Army, Spanish Air Force, and Spanish Marine Infantry (Infantería de Marina, a branch of the Armada) general de brigada is the lowest rank of general officers. Its equivalent in the Navy (Armada) is contraalmirante.

In the Swedish Army, Swedish Air Force and Swedish Amphibious Corps brigadgeneral is the lowest rank of general officers. Its equivalent in the Navy is flottiljamiral.

In the Turkish Army and the Turkish Air Force, the equivalent rank is tuğgeneral (the Turkish Navy equivalent would be tuğamiral). The name is derived from tugay, the Turkish word for a brigade. Both tugay and tuğ- as military terms may owe their origins to the older Turkish word tuğ, meaning horsetail, which was used as a symbol of authority and rank in Ottoman and pre-Ottoman times.

Brigadier-general was formerly a rank or appointment in the British Army and Royal Marines, and briefly in the Royal Air Force. The appointment was abolished in both the Army and the Marines in 1921 and the equivalent rank today is simply Brigadier.
