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.

Unified combatant commands are organized either on

There was no overall headquarters for the ground elements within the Far East Command, and the five separate ground commands reported directly to CINCFE. Far East Air Forces and Naval Forces Far East also reported directly to CINCFE, initially giving MacArthur seven subordinate military headquarters. The Marianas-Bonins Command (MARBO)
252-641: A civil administration for the Ryukyu Islands in accordance with JCS 1231/14 October 4, 1950. USCAR continued to function under the Department of the Army (formerly the War Department) from 1950 to 1971.

294-514: 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)

#1732775845915504-483: 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.

588-549: The Pacific War proved more difficult to organize, as neither General of the Army Douglas MacArthur nor Fleet Admiral Chester W. Nimitz was willing to be subordinate to the other, for reasons of interservice rivalry . 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
630-561: The Unified Command Plan of 1956–1957. A 1958 "reorganization in National Command Authority relations with the joint commands" with a "direct channel" to unified commands such as Continental Air Defense Command (CONAD) was effected after President Dwight Eisenhower expressed concern about nuclear command and control. CONAD itself was disestablished in 1975. Although not part of the original plan,
672-545: The United States Armed Forces . Historically, a Major Command is the highest level of command. Within the United States Army , the acronym MACOM is used for Major Command.

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. A sub-unified command, or, subordinate unified command, may be established by combatant commanders when authorized to do so by

Furthermore, the Secretaries of the Military Departments (i.e., Secretary of

Sub-unified commands may be either functional or geographic, and the commanders of sub-unified commands exercise authority similar to that of combatant commanders. Examples of former and present sub-unified commands are the Alaskan Command (ALCOM) under USNORTHCOM ,
1134-559: 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 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
1386-483: 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
1428-650: The dwindling US military strength in Japan and Korea, which cast doubt on the advisability of a separate command for that region. The lone dissenter was the CSA, who argued that an attempt to split up CINCFE’s multiple functions—as a US commander, as commander of the UNC in Korea, and as military governor of the Ryukyu Islands would produce inefficiency and higher costs. He wanted the Far East Command to be expanded, with CINCFE given responsibility for Southeast Asia, Taiwan, Indonesia, and

1554-879: The terms of Article II of the United States Constitution . Thereafter, the military CINCs would be known as "combatant commanders", as heads of the unified combatant commands.

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.

In 1951, during the Korean War , the Joint Chiefs of Staff shifted responsibility for the Bonins and Marianas as well as the Philippines and Taiwan from FECOM to PACOM. The United States Civil Administration of the Ryukyu Islands (USCAR) was established, effective 15 December 1950, by a directive of Headquarters Far East Command. That directive ordered Commander-in-Chief Far East, Gen. Douglas MacArthur, to organize

The Navy saw all Pacific islands as one strategic entity, while the Army insisted that FECOM be able to draw upon military resources in

Each combatant command (CCMD) 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.
