US Forces Korea
This is a "best available" order-of-battle of forces deployed in US Forces Korea area of responsibility. Even prior to September 11, 2001, the amount of publicly available information concerning aircraft types and specific units at particular locations. The presence of significant numbers of civilian contractor personnel and of military families at various facilities in the region further complicates accounting for total personnel numbers.
There are normally about 37,500 military personnel stationed in the USFK area of responsibility, including about 225 aircraft of all types. The number of troops deployed in the area does not normally fluctuate.
Beginning on 21 March 2004 there were an additional 8,500 military personnel in the AOR as part of RSOI/FE 2004. Those personnel departed the region by April 2004.
Ground forces include a variety of units that are normally deployed in the region. Forces in the region include Patriot missile batteries, Apache helicopter squadrons, a mechanized infantry brigade, an air assault brigade, various support, intelligence and other units. The total Army presence in the region is nearly 27,500 soldiers. However, it is important to point out that the Department of Defense indicated during a briefing on July 23, 2003 that the United States Army had some 4,000 additional soldiers in South Korea than what had been previously disclosed by the military. It is not clear is this is a mistake or not. If true, this would bring the total number of soldiers in South Korea to 31,460.
The Air Force has two wings located in the USFK region with some 8,300 personnel, operating a total of about 100 aircraft of all types.
US Naval Forces, Korea is particularly small, numbering around 293 sailors and 52 marines. CNFK normally has no seagoing forces assigned, though its personnel are assigned to various joint, combined, and Navy billets throughout the ROK peninsula. These personnel are actively engaged in planning and execution of numerous operations and exercises throughout the Korean theater. There is one ship that has been present in the region for over 30 years, that being the USS Pueblo which was captured on 23 January 1968. She is currently located at Pyongyang.
US Non-military individuals in Korea can be divided into two categories, contractors and family members. There are roughly 4,000 contractors and and 11,500 family members in Korea at any given time.
The Korean Augmentation to the United States Army, or KATUSA, program was initiated by GEN Douglas MacArthur in August 1950. Today, KATUSA soldiers are integrated into virtually all Army units in Korea, from squad level up. They live, work and train with their American counterparts. At its peak in 1952, KATUSA strength had reached 27,000. KATUSA strength declined after the 1953 armistice. In July 1971, following the reduction of American troops in Korea, the number of KATUSAs assigned to serve with U.S. Army units stabilized at about 7,000. KATUSAs are usually assigned to a unit for two years -- providing continuity of operations and expertise that might be lost as a result of one-year rotations by US soldiers.
