Organizational Levels of U.S. Ground
Forces
The Congressional Budget Office's (CBO's), The U.S.
Military's Force Structure: A Primer, 2021 Update, notes:
The Army and Marine Corps are generally
organized as hierarchies of units, with each type of
unit commanded by a noncommissioned or
commissioned officer of a specific rank. These units
are described from smallest to largest.
Squad/Team/Section. A squad is led by a sergeant and
consists of 4-12 personnel. Squads can be further divided
into teams or sections.
Platoon. A platoon-led (Army) or commanded (Marines)
by a lieutenant and includes varying numbers of
subordinate squads, teams, or sections-may vary from 16
to 50 personnel. Heavy platoons have armored vehicles,
such as tanks or infantry fighting vehicles, depending on
platoon type.
Company/Troop/Battery. A company is commanded by a
captain and includes two to five subordinate platoons
(usually three or four). It has about 60-200 personnel.
Cavalry (air or ground) companies are called troops (Army
only); artillery and air and missile defense companies are
called batteries.
Battalion/Squadron. A battalion is commanded by a
lieutenant colonel and usually includes three to five combat
companies and a support company. It has about 400-1,000
personnel. Cavalry battalions are called squadrons.
Brigade Combat Team/Support
Brigades/Regiment/Group. Army brigades are
commanded by a colonel and generally are configured as a
brigade combat team (BCT) or a support brigade. A BCT
has about 4,000-4,700 personnel, depending on type. Army
cavalry brigades are called regiments; some types of
support brigades are called groups. Marine Corps units at
this level also are called regiments. (The term Marine
Expeditionary Brigade [MEB] refers to a regimental-size
task force, which is larger than an Army Brigade Combat
Team [BCT]).
Division. An Army division is commanded by a major
general and includes two to five BCTs (usually four), an
aviation brigade, an artillery brigade, an engineer brigade,
and a logistics brigade. Army divisions consist of 12,000-
16,000 personnel. Marine divisions, also commanded by
major generals, consist of three regiments and supporting
units, and consist of about 6,600 personnel.
Corps. Corps are commanded by a lieutenant general and
include two to five divisions and numerous support
brigades and commands. Corps have about 40,000-100,000
personnel. The Marines do not have designated corps,
although a Marine Expeditionary Force (MEF) is similar in
size and also is commanded by a lieutenant general.
Army. An army is the highest command level in a given
theater of operations and typically has 100,000-300,000
personnel. It is an element of a joint command structure,
with the Army's component commanded by a general. An
Army's operational theater is established to support one or
more corps and includes numerous support brigades and
support commands.
