Description
A battalion comprises two or more primary mission companies which are often of a common type (e.g., infantry, tank, or maintenance), although there are exceptions such as combined arms battalions in the U.S. Army. In addition to the primary mission companies, a battalion typically includes a headquarters staff and combat service support which may be combined into a Headquarters and service company. A battalion may also contain a combat support company. With all these components, a battalion is the smallest military unit capable of "limited independent operations".
The battalion must have a source of re-supply to enable it to sustain operations for more than a few days. This is because a battalion's complement of ammunition, expendable weapons (e.g., hand grenades and disposable rocket launchers), water, rations, fuel, lubricants, replacement parts, batteries, and medical supplies normally consists of only what the battalion's soldiers and the battalion's vehicles can carry.
The commander's staff coordinates and plans operations. A battalion's subordinate companies and their platoons are dependent upon the battalion headquarters for command, control, communications, and intelligence, and the battalion's service and support structure. The battalion is usually part of a

Battalions are tactical and administrative organizations with a limited capability to plan and conduct independent operations and are normally organic components of brigades, groups, or regiments.
A U.S. Army battalion includes the battalion commander ( lieutenant colonel), executive officer ( major), command sergeant major (CSM), headquarters staff, and usually three to five companies, with a total of 300 to 1,000 (but typically 500 to 600) soldiers. A regiment consists of between two and six organic battalions, while a brigade consists of between three and seven separate battalions.

, an infantry or cavalry battalion was an ad hoc grouping of companies from the parent regiment (which had ten companies, A through K, minus J as described below), except for certain regular infantry regiments, which were formally organized into three battalions of six companies each (numbered 1–6 per battalion vice sequential letter designations). After 1882, cavalry battalions were renamed squadrons and cavalry companies were renamed troops. Artillery battalions typically comprised four or more batteries, although this number fluctuated considerably.
During World War II, most infantry regiments consisted of three battalions (1st, 2nd, and 3rd) with each battalion consisting of three rifle companies and a heavy weapons company. That is, rifle companies A, B, C along with heavy weapons Company D were part of the 1st battalion, rifle companies E, F, G, and heavy weapons Company H constituted the 2nd battalion, and rifle companies I, K, L, and heavy weapons Company M were in the 3rd. There was no J Company: the letter ''J'' was traditionally not used because in 18th- and 19th-century old-style type, the capital letters ''I'' and ''J'' looked alike, and were therefore easily confused with one another. It was common for a battalion to become temporarily attached to a different regiment. For example, during the confusion and high casualty rates of both the

sections and man-portable air-defense system sections. Beginning in the early 1980s, some elements of the combat support companies (the mortar and scout platoons) were merged into the headquarters company with the staff and support elements, others were moved to their parent type organization (ground surveillance radar and air defense), and in infantry battalions the heavy anti-tank missile platoon was organized as a separate company (E Company). In the late 1980s, there was a fourth "line" company added (D Company) in most infantry and tank battalions.
In this older structure, U.S. Army mechanized infantry battalions and tank battalions, for tactical purposes, task-organized companies to each other, forming a battalion-sized task force (TF).
Starting in 2005–2006, the U.S. Army's mechanized and tank battalions were reorganized into combined arms battalions (CABs). Tank battalions and mechanized infantry battalions no longer exist. These new combined arms battalions are modular units, each consisting of a headquarters company, two mechanized infantry companies, two tank companies, and a forward support company attached from the battalion's parent brigade support battalion. This new structure eliminated the need to task-organize companies between battalions; each combined arms battalion was organically composed of the requisite companies. At a higher level, each armored brigade (formerly designated 'heavy brigade') is now composed of three CABs (versus the two CABs of a former heavy brigade), one reconnaissance squadron, one artillery battalion, one brigade engineer battalion (BEB), and one brigade support battalion (BSB).
