The United States Central Command (USCENTCOM or CENTCOM) is an institution, specifically one of the eleven unified combatant commands of the United States Department of Defense. It is a geographic combatant command responsible for protecting American security interests across a vast area of responsibility (AOR) that stretches from the Horn of Africa to Central Asia.
The command was formally established on January 1, 1983, by President Ronald Reagan. Its creation was a response to the geopolitical turmoil of the late 1970s, particularly the Iranian hostage crisis and the Soviet invasion of Afghanistan. CENTCOM was designed as a permanent, regionally-focused replacement for the less specific Rapid Deployment Joint Task Force (RDJTF), which President Jimmy Carter had established in March 1980 to strengthen the U.S. presence in the region.
CENTCOM's mechanism involves organizing and coordinating forces from all U.S. armed services into a cohesive war-fighting and security institution. It directs military operations and activities with allies to increase regional stability. The command operates through various service component commands, such as U.S. Army Central (ARCENT) and U.S. Naval Forces Central Command (NAVCENT). While its main headquarters is at MacDill Air Force Base in Tampa, Florida, it maintains a forward headquarters at Al Udeid Air Base in Qatar.
CENTCOM connects to the broader U.S. military structure as one of the unified combatant commands, with its AOR situated between the European Command (EUCOM) and the Indo-Pacific Command (INDOPACOM). Its AOR encompasses 21 nations, including Iraq, Iran, Pakistan, and Afghanistan. A significant recent change occurred in January 2021, when Israel was added as the 21st country to the CENTCOM AOR. Earlier, in 2008, most of the African nations in its AOR were transferred to the newly created U.S. Africa Command (AFRICOM).
