Military Command: Organizational Structures and Major Commands
In military terminology, a command serves as the fundamental organizational unit for which a specific military commander holds responsibility. These commands, which are also frequently referred to as units or formations, act as the essential building blocks of a military force, ensuring that authority and responsibility are clearly defined across the organization.
While naval and military officers possess general legal authority through their officer's commission, the specific privileges and responsibilities associated with a command are only granted through a formal publication of appointment. This process establishes the necessary legal framework for the authority bestowed upon the commander.
Defining Command
The United States Department of Defense (US DOD) provides a precise definition of a command (often abbreviated as CMD). According to the DOD, a command is a unit or units, an organization, or a specific area under the command of one individual. This definition encompasses various scales of operation, ranging from localized area commands to broad combatant commands.
