Editing Battalion (section)

=== United States Marine Corps ===
{{see also|List of United States Marine Corps battalions}}
A [[United States Marine Corps]] battalion includes the battalion headquarters, consisting of the commanding officer (usually a lieutenant colonel, sometimes a colonel), an [[executive officer]] (the second-in-command, usually a major), the [[sergeant major]] and the executive staff (S-1 through S-4 and S-6). The battalion headquarters is supported by a [[headquarters and service company]] (battery). A battalion usually contains two to five organic companies (batteries in the artillery), with a total of 500 to 1,200 Marines in the battalion. A regiment consists of a regimental headquarters, a headquarters company (or battery) and two to five organic battalions (Marine infantry regiments – three battalions of infantry; Marine artillery regiments – three to five battalions of artillery; Marine combat logistics regiments – one to three combat logistics battalions). In the U.S. Marine Corps, the brigade designation is used only in "[[Marine Expeditionary Brigade]]" (MEB). An MEB is one of the standard [[Marine Air-Ground Task Force]]s (MAGTF), is commanded by a [[brigadier general]] or [[major general]], and consists of command element, a [[ground combat element]] (usually one reinforced Marine infantry regiment), an [[aviation combat element]] (a reinforced Marine aircraft group including rotary wing, fixed wing and tiltrotor aircraft) and a combat logistics element (a Marine combat logistics regiment, which includes naval construction forces [Seabees] and naval medical elements).

In the U.S. Marine Corps, an infantry or "rifle" battalion typically consists of a headquarters and service company, three rifle or "line" companies (designated alphabetically A through M depending upon which battalion of the parent regiment to which they are attached) and a weapons company. Weapons companies do not receive a letter designation. Marine infantry regiments use battalion and company designations as described above under World War II, with company letters D, H and M not normally used but rather held in reserve for use in augmenting a fourth rifle company into each battalion as needed.

United States Marine Corps infantry battalions are task organised into Battalion Landing Teams (BLTs) as the ground combat element (GCE) of a [[Marine Expeditionary Unit]] (MEU). A standard U.S. Marine infantry battalion is typically supported by an [[artillery battery]] and a platoon each of tanks, amphibious assault vehicles, light armoured reconnaissance vehicles, reconnaissance Marines and combat engineers. The battalion structure is designed to readily expand to include a fourth rifle company, if required, as described above under battalion organisation. Often [[Air Naval Gunfire Liaison Company]] (ANGLICO) officers are assigned to the battalion, to coordinate [[naval gunfire support#United States|naval gunfire support]].
