(Fr. and Ger. brigade, Ital. brigata, Span. brigada; the English use of the word dates from the early 17th century), a unit in military organization commanded by a major-general, brigadier-general or colonel, and composed of two or more regiments of infantry, cavalry or artillery. The British infantry brigade consists as a rule of four battalions (or about 4000 bayonets) with supply, transport and medical units attached; the cavalry brigade of two or three regiments of cavalry. An artillery "brigade" (field, horse, and heavy) is in Great Britain a smaller unit, forming a lieut.-colonel's command and consisting of two or three batteries. (See Army, Artillery, Infantry, and Cavalry.) The staff of an infantry or cavalry brigade usually consists of the brigadier commanding, his aide-de-camp, and the brigade-major, a staff officer whose duties are intermediate between those of an adjutant and those of a general staff officer.
