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.
Tank Platoon. The tank platoon is the smallest maneuver element within a tank company. Organized to fight as a unified element, the platoon consists of four main battle tanks organized into two sections, with two tanks in each section. Tank platoons usually operate as a whole or by section and do not normally deploy individual tanks.
