United States Forces Korea

The United States Forces Korea (USFK) is a sub-unified command of U.S. Indo-Pacific Command (USINDOPACOM). USFK is the joint headquarters for U.S. combat-ready fighting forces and components under the ROK/US Combined Forces Command (CFC) – a supreme command for all of the South Korean and U.S. ground, air, sea and special operations component commands. Major USFK elements include U.S. Eighth Army (EUSA), U.S. Air Forces Korea (Seventh Air Force), U.S. Naval Forces Korea (CNFK), U.S. Marine Forces Korea (MARFORK) and U.S. Special Operations Command Korea (SOCKOR). It was established on July 1, 1957.

Its mission is to support the United Nations Command (UNC) and Combined Forces Command by coordinating and planning among U.S. component commands, and exercise operational control of U.S. forces as directed by United States Indo-Pacific Command.

USFK has Title 10 authority, which means that USFK is responsible for organizing, training and equipping U.S. forces on the Korean Peninsula so that forces are agile, adaptable and ready.

With 28,500 U.S. soldiers, sailors, airmen, and marines in South Korea, U.S. forces in South Korea are a major presence in the region and a key manifestation of the U.S. government's aim to rebalance toward the Asia-Pacific. The USFK mission also includes planning non-combatant evacuation operations to ensure that if the need arises, U.S. and other previously agreed-upon countries' citizens are removed from harm's way. To this end, USFK conducts routine exercises to ensure that this process is effective, efficient, and orderly.

With the relocation of the new USFK and UNC headquarters to Camp Humphreys (in Pyeongtaek) on 29 June 2018, the USFK command and the majority of its subordinate units have officially moved out of the city of Seoul; headquarters are now 35 km (22 mi) further south.
