A battalion is a military unit with 300 to 1,200 soldiers that usually consists of two to seven companies and is commanded by either a lieutenant colonel or a colonel. Several battalions form a regiment or brigade. The nomenclature varies by nationality and by branch of arms, for instance, some armies organize their infantry into battalions, but call battalion-sized cavalry, reconnaissance, or tank units a squadron or a regiment instead.
By 1776 a typical infantry regiment had a regimental staff and eight companies. Along with three field officers and six staff officers, the regimental staff â¦ included four staff NCOs: a sergeant major, a quartermaster sergeant, and two lead musicians (a drum major and a fife major).
