Unified combatant command A unified combatant command
), also referred to as a combatant command
, is a joint military command
of the United States Department of Defense
that is composed of units from two or more service branches
of the United States Armed Forces
, and conducts broad and continuing missions.
There are currently 11 unified combatant commands and each are established as the highest echelons of military commands, in order to provide effective command and control
of all U.S. military
forces, regardless of branch of service, during peace or during war time.
Unified combatant commands are organized either on a geographical basis (known as "area of responsibility
", AOR) or on a functional basis, i.e. special operations
, power projection
, and cybersecurity
. Currently, seven combatant commands are designated as geographical, and four are designated as functional. Unified combatant commands are "joint" commands and have specific badges denoting their affiliation.
Unified combatant commands areas of responsibility
The Unified Command Plan (UCP) establishes the missions, command responsibilities, and geographic areas of responsibility of the combatant commands.
Each time the Unified Command Plan is updated, the organization of the combatant commands is reviewed for military efficiency and efficacy, as well as alignment with national policy.
Four types of command authority can be distinguished:
- COCOM – combatant command: unitary control (not further delegatable by the combatant commander CCDR)
- ADCON - administrative control of the command function of "obtaining resources, direction for training, methods of morale and discipline"
- OPCON - operational control of a command function say, sustainment. In that case, OPCON is embodied in the Army Field Support Brigades (AFSBs)
- TACON - tactical control of say, sustainment, as embodied in a Contracting Support Brigade
List of combatant commands
Geographic areas of responsibility for six land-based geographic combatant commands
Currently, four geographic combatant commands have their headquarters
located outside their geographic area of responsibility.

The current system of unified commands in the U.S. military emerged during World War II
with the establishment of geographic theaters of operation composed of forces from multiple service branches that reported to a single commander who was supported by a joint staff.
A unified command structure also existed to coordinate British and U.S. military forces operating under the Combined Chiefs of Staff
, which was composed of the British Chiefs of Staff Committee
and the U.S. Joint Chiefs of Staff
World War II era
The Joint Chiefs of Staff continued to advocate in favor of establishing permanent unified commands, and President Harry S. Truman
approved the first plan on 14 December 1946.
Known as the "Outline Command Plan," it would become the first in a series of Unified Command Plans.
The original "Outline Command Plan" of 1946 established seven unified commands: Far East Command
, Pacific Command
, Alaskan Command
, Northeast Command
, the U.S. Atlantic Fleet
, Caribbean Command, and European Command. However, on 5 August 1947, the CNO recommended instead that CINCLANTFLT be established as a fully unified commander under the broader title of Commander in Chief, Atlantic (CINCLANT). The Army and Air Force objected, and CINCLANTFLT was activated as a unified command on 1 November 1947. A few days later, the CNO renewed his suggestion for the establishment of a unified Atlantic Command. This time his colleagues withdrew their objections, and on 1 December 1947, the U.S. Atlantic Command
(LANTCOM) was created under the Commander in Chief, Atlantic (CINCLANT).
Under the original plan, each of the unified commands operated with one of the service chiefs (the Chief of Staff of the Army
or Air Force
, or the Chief of Naval Operations
) serving as an executive agent representing the Joint Chiefs of Staff.
This arrangement was formalized on 21 April 1948 as part of a policy paper titled the "Function of the Armed Forces and the Joint Chiefs of Staff" (informally known as the "Key West Agreement
The responsibilities of the unified commands were further expanded on 7 September 1948 when the commanders' authority was extended to include the coordination of the administrative and logistical functions in addition to their combat responsibilities.
Cold War era
Far East Command and U.S. Northeast Command were disestablished under the Unified Command Plan
Although not part of the original plan, the Joint Chiefs of Staff
also created specified commands that had broad and continuing missions but were composed of forces from only one service.
Examples include the U.S. Naval Forces, Eastern Atlantic and Mediterranean and the U.S. Air Force's Strategic Air Command. Like the unified commands, the specified commands reported directly to the JCS instead of their respective service chiefs.
These commands have not existed since the Strategic Air Command was disestablished in 1992. The relevant section of federal law, however, remains unchanged, and the President retains the power to establish a new specified command.
The Goldwater–Nichols Defense Reorganization Act
of 1986 clarified and codified responsibilities that commanders-in-chief (CINCs) undertook, and which were first given legal status in 1947. After that act, CINCs reported directly to the United States Secretary of Defense
, and through him to the President of the United States.
Post Soviet era
The U.S. Atlantic Command became the Joint Forces Command
in the 1990s after the Soviet threat to the North Atlantic had disappeared and the need rose for an integrating and experimentation command for forces in the continental United States. Joint Forces Command
was disbanded on 3 August 2011 and its components placed under the Joint Staff
and other combatant commands.
A sixth geographical unified command, United States Africa Command
(USAFRICOM), was approved and established in 2007 for Africa. It operated under U.S. European Command as a sub-unified command during its first year, and transitioned to independent Unified Command Status in October 2008. In 2009, it focused on synchronizing hundreds of activities inherited from three regional commands that previously coordinated U.S. military relations in Africa.
President Donald Trump
announced on 18 August 2017 that the United States Cyber Command
(USCYBERCOM) would be elevated to the status of a unified combatant command from a sub-unified command. It was also announced that the separation of the command from the NSA
would be considered.
USCYBERCOM was elevated on 4 May 2018.
Vice President Mike Pence
announced on 18 December 2018 that President Donald Trump had issued a memorandum ordering the stand-up of a United States Space Command
A previous unified combantant command for unified space operations was decommissioned in 2002. The new USSPACECOM will include "(1) all the general responsibilities of a Unified Combatant Command; (2) the space-related responsibilities previously assigned to the Commander, United States Strategic Command
; and (3) the responsibilities of Joint Force Provider and Joint Force Trainer for Space Operations Forces".
USSPACECOM was re-established on 29 August 2019.
Each combatant command (CCMD, also COCOM) is headed by a four-star general or admiral (the CCDR) recommended by the Secretary of Defense, nominated for appointment by the President of the United States, confirmed by the Senate and commissioned, at the President's order, by the Secretary of Defense. The Goldwater–Nichols Act and its subsequent implementation legislation also resulted in specific Joint Professional Military Education
(JPME) requirements for officers before they could attain flag or general officer rank thereby preparing them for duty in Joint assignments such as UCC staff or Joint Chiefs of Staff assignments, which are strictly controlled tour length rotations of duty. However, in the decades following enactment of Goldwater–Nichols, these JPME requirements have yet to come to overall fruition. This is particularly true in the case of senior naval officers, where sea duty / shore duty rotations and the culture of the naval service has often discounted PME and JPME as a measure of professional development for success. Although slowly changing, the JPME requirement still continues to be frequently waived in the case of senior admirals nominated for these positions.
The operational chain of command runs from the President
to the Secretary of Defense
to the combatant commanders of the combatant commands. The Chairman of the Joint Chiefs of Staff
may transmit communications to the Commanders of the combatant commands from the President and Secretary of Defense and advises both on potential courses of action, but the Chairman does not exercise military command over any combatant forces. Under Goldwater–Nichols, the service chiefs (also four stars in rank) are charged with the responsibility of the "strategic direction, unified operation of combatant commands, and the integration of all land, naval, and air forces in an efficient "unified combatant command" force. Furthermore, the Secretaries of the Military Departments (i.e. Secretary of the Army
, Secretary of the Navy
, and the Secretary of the Air Force
) are legally responsible to "organize, train and equip" combatant forces and, as directed by the Secretary of Defense, assign their forces for use by the combatant commands. The Secretaries of the Military Departments thus exercise administrative control (ADCON)
rather than operational control (OPCON—the prerogative of the combatant commander) over their forces.
Sub-unified combatant commands
A sub-unified command, or, subordinate unified command, may be established by combatant commanders when authorized to do so by the Secretary of Defense or the president.
They are created to conduct a portion of the mission or tasking of their parent geographic or functional command. Sub-unified commands may be either functional or geographic, and the commanders of sub-unified commands exercise authority similar to that of combatant commanders.
