Not to be confused with military order (instruction).

This is about a structural 'command' of a military service branch (army, navy, or air force), and NOT about 'commanding officers' or similar leaders (nor their appointment). A 'command' is the first subordinate tier of an army, navy, or air force (and therefore the largest by personnel and equipment); in air force terminology (British, Commonwealth, and most others except USAF), it is superior to group, the organisational structure reducing in size to wing, then squadron, then flight's factual accuracy is disputed . Relevant discussion may be found on the talk page. Please help to ensure that disputed statements are reliably sourced. (December 2024) (Learn how and when to remove this message)

A command in military terminology is an organisational unit for which a military commander is responsible. Commands, sometimes called units or formations, form the building blocks of a military. A commander is normally specifically appointed to the role in order to provide a legal framework for the authority bestowed. Naval and military officers have legal authority by virtue of their officer's commission, but the specific responsibilities and privileges of command are derived from the publication of appointment.

The relevant definition of 'command' according to the United States Department of Defense (US DOD) is as follows:^[1]

(DOD) 3. A unit or units, an organization, or an area under the command of one individual. Also called CMD. See also area command; combatant command; combatant command (command authority).
