A '''unified combatant command''', also referred to as a '''combatant command''' ('''CCMD'''), is a joint [[command (military formation)|military command]] of the [[United States Department of Defense]] that is composed of units from two or more [[service branch]]es of the [[United States Armed Forces]], and conducts broad and continuing missions.<ref>''Joint Pub 1'', p. GL-11.</ref> There are currently 11 unified combatant commands, and each is established as the highest echelon 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.<ref>Story, p. 2</ref> Unified combatant commands are organized either on a geographical basis (known as an "[[area of responsibility]]", AOR) or on a functional basis, e.g., [[special operations]], [[force projection]], [[military supply-chain management|transport]], and [[United States Cyber Command|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.

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.<ref>JCS (1977), p. 2</ref> Known as the "Outline Command Plan", it would become the first in a series of Unified Command Plans.<ref>{{Cite book |last=Max Ostrovsky |url=https://archive.org/details/military-globalization/page/241/mode/2up?q=combatant&view=theater |title=Military Globalization |date=2018-08-01}}</ref> The original "Outline Command Plan" of 1946 established seven unified commands: [[Far East Command (United States)|Far East Command]], [[United States Pacific Command|Pacific Command]], [[Alaskan Command]], [[U.S. Northeastern 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).<ref>Joint History Office, ''History of the Unified Command Plan 1946–1993'', pp. 14–15.</ref>

Under the original plan, each of the unified commands operated with one of the service chiefs (the [[Chief of Staff of the United States Army|Chief of Staff of the Army]] or [[Chief of Staff of the United States Air Force|Air Force]], or the [[Chief of Naval Operations]]) serving as an executive agent representing the Joint Chiefs of Staff.<ref>JCS (1977), p. 3.</ref> 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]]").<ref>JCS (1977), p. 5.</ref> 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.<ref>JCS (1977), p. 6.</ref>
