. Brigades formed into divisions are usually infantry or armored (sometimes referred to as combined arms brigades). In addition to combat units, they may include combat support units or sub-units, such as artillery and engineers, and logistic units. Historically, such brigades have sometimes been called brigade-groups. On operations, a brigade may comprise both organic elements and attached elements, including some temporarily attached for a specific task. Brigades may also be specialized and comprise battalions of a single branch, for example cavalry, mechanized, armored, artillery, air defence, aviation, engineers, signals or logistic. Some brigades are classified as independent or separate and operate independently from the traditional division structure. The typical

. In some armies, the commander is rated as a general officer. The brigade commander has a self-contained headquarters and staff. The principal staff officer, usually a lieutenant colonel or colonel, may be designated chief of staff. Until the late 20th century British and similar armies called the position 'brigade-major’ and most British brigades have a major as the chief of staff. Some brigades may also have a deputy commander. The headquarters has a nucleus of staff officers and support (clerks, assistants and drivers) that can vary in size depending on the type of brigade. On operations, additional specialist elements may be attached. The headquarters will usually have its own communications unit. In some gendarmerie forces, brigades are the basic-level organizational unit.


Origin

The term brigade first entered the English language, like most military terms, from the French language. The word is first attested in the 15th century as a term for a larger military unit than the squadron or regiment. In England, it was first adopted when armies began to consist of formations larger than a single regiment. The term's origin is found in two French roots, which together meant roughly “those who fight.”. Previously each regiment, battalion, cavalry squadron, or artillery battery operated somewhat independently, with its own field officer (i.e., colonel, lieutenant colonel, or major) or battery commander (usually a captain) reporting directly to the field force or "army" commander. As such a "field army" became larger, the number of subordinate commanders became unmanageable for the officer in general command of said army, usually a major general, to effectively command. In order to streamline command relationships, as well as effect some modicum of tactical control, especially in regard to combined arms operations (i.e., those involving a coordination of infantry with cavalry and/or artillery forces), an intermediate level of command came into existence. The Swedish king Gustavus Adolphus improved the brigade as a tactical unit, introducing it in 1631 during a reorganization of the Swedish Army in the course of the Thirty Years' War. The invention of the brigade overcame the lack of coordination inherent in the traditional army structure consisting of independent regiments of infantry and units of supporting arms (viz., cavalry and artillery) acting separately under their individual commanding officers. Gustavus Adolphus accomplished this battlefield coordination by combining battalions of infantry with cavalry troops and artillery batteries into a "battle group", viz., ''brigada'' or "brigade" commanded by a senior colonel, or lieutenant colonel, appointed as a ''brigadier-general.'' In France, Marshal Turenne (1611–1675) copied the brigade organization ; he made it a permanent standing unit, requiring the creation in 1667 of a permanent rank of (literally translating to "brigadier of the armies of the king"). Unlike the Swedish brigades, French brigades at that time comprised two to five regiments of the same branch ( etc.). The rank, intermediate between colonel and disappeared in 1788 and should not be confused with that of which is equivalent to a brigadier general. (A modern is referred to occasionally as .)


By country


Argentina

In the Argentinian Army, the typical brigade comprises an HQ company, two or three battalions (called "regiments" for historical reasons) of the brigade's main branch (infantry or armoured cavalry), which give the brigade its denomination (mechanized, armoured, airborne, mountain or jungle), plus one battalion of the other branch, plus one or two artillery groups, an engineers battalion or company, a signals company, and intelligence company, an army aviation section and a logistics battalion. Mountain brigades have also a special forces (called "Mountain rangers") company. The brigade is usually commanded by a brigadier general or a senior colonel, who may be promoted to general during his tenure as brigade commander.


Australia

In the Australian Army, the brigade has always been the smallest tactical formation, since regiments are either administrative groupings of battalions (in the

) or battalion-sized units (in the cavalry). A typical brigade may consist of approximately 5,500 personnel between two mechanised infantry battalions, an armoured regiment, an armoured artillery regiment, and other logistic and engineering units. The brigade is usually commanded by an officer holding the rank of brigadier, who is referred to as the "Brigade Commander".

Pakistan

A brigade is under the command of a brigadier and comprises three or more battalions of different units depending on its functionality. An independent brigade would be one that primarily consists of an artillery unit, an infantry unit, an armour unit and logistics to support its actions. Such a brigade is not part of any division and is under direct command of a corps. There are 7 independent armoured brigades, seven engineering brigades and eight air defense brigades. Independent armoured and infantry brigades are capable of extended operations without necessarily being reliant on a higher HQ for short-term logistic or intimate support. They can be used in counter-attack, exploitation of an advance, or rapid movement to reinforce formations under pressure.

The brigade is intended to be combat ready at all times. The combat battalions have a significant portion of professional soldiers (specialists). The fairly large size of the combat ready support contingent is also intended to complement the Heimevernet (translates as "Home Defense") which is a large reserve infantry force, as well as act in a support capacity for an international cooperation force (e.g. NATO) in case of an invasion.


France

France replaced its divisions with brigades in 1999 (so for example the 2nd Armored Division became the 2nd Armored Brigade). It was decided in 2016 to again form two divisions ( 1st and 3rd) made up of four and three brigades for a total of seven brigades: two armored, two "intermediate", two light brigades (alpine and parachute) and the

United Kingdom

Brigades, with a field not a regional administrative role, have usually been of a named type and numbered since the 19th century (e.g. cavalry brigade or infantry brigade). Since the end of World War II, brigade numbers have been unique and not by type. Brigades in divisions do not usually command their combat support and combat service support units. These remain under divisional command, although they may be permanently affiliated with a particular brigade (as a "brigade group"). Historically, infantry or cavalry/armoured brigades have usually comprised three or four combat-arm battalions, but currently larger brigades are normal, made larger still when their affiliated artillery and engineer regiments are added. Until 1918, the chief of staff of a brigade was known as a
brigade major A brigade major was the chief of staff of a brigade in the British Army. They most commonly held the rank of major, although the appointment was also held by captains, and was head of the brigade's "G - Operations and Intelligence" section dire ...
. Before 1922, British Army brigades were normally commanded by general officers holding the rank of brigadier-general (equivalent to a "one-star" rank in the US army); after that date, the brigade commander was an appointment for officers with the rank of brigadier, which were then classified as field officers not general officers. This is universally the case today. From 1859 to 1938, "brigade" ("brigade-division" 1885–1903) was also the term used for a battalion-sized unit of the Royal Artillery. This was because, unlike infantry battalions and cavalry regiments, which were organic, artillery units consisted of individually numbered batteries that were "brigaded" together. The commanding officer of such a brigade was a lieutenant colonel. In 1938, the Royal Artillery adopted the term "regiment" for this size of unit, and "brigade" became used in its normal sense, particularly for groups of anti-aircraft artillery regiments commanded by a brigadier. In the Second World War, a tank brigade comprised three tank regiments and was equipped with infantry tanks for supporting the infantry divisions. Armoured brigades were equipped with cruiser tanks or (US Lend-Lease) medium tanks and a motorised infantry battalion. The armoured divisions included one or more armored brigades.
