Camp Humphreys

Camp Humphreys, also designated United States Army Garrison-Humphreys (USAG-H), is located near Pyeongtaek and Anjeong-ri, South Korea. The site was established in 1919 as Pyeongtaek Airfield by the Japanese military. During the Korean War, the U.S. Air Force repaired the facility and designated it K-6. In 1962, the base was renamed in honor of Chief Warrant Officer Benjamin K. Humphreys. The installation transitioned from a district command to a U.S. Army Garrison in 1974. Following a 2004 land-swap agreement between the United States and South Korea, the base underwent an $11 billion expansion to facilitate the relocation of U.S. forces from Yongsan Garrison in Seoul and other positions north of the Han River.

The garrison is operated by the United States Army and serves as the headquarters for United States Forces Korea, United Nations Command, and Combined Forces Command. Stationed units include the Eighth United States Army, the 2nd Infantry Division, the 2nd Combat Aviation Brigade, and the 501st Military Intelligence Brigade. The installation also hosts the 1st Signal Brigade, the 65th Medical Brigade, and the 411th Contract Support Brigade. Rotational units, including an Armored Brigade Combat Team and a Heavy Attack Recon Squadron, are frequently deployed to the base.

The installation covers 3,538 acres and houses approximately 500 buildings. Its primary aviation facility, Desiderio Army Airfield, supports aircraft types including CH-47 Chinooks, UH-1N Iroquois, and military intelligence platforms such as the RC-12X and RC-7. Infrastructure includes twelve 12-story housing towers and medical facilities provided by the Brian D. Allgood Army Community Hospital. Educational facilities consist of four schools operated by the Department of Defense Education Activity. Support infrastructure includes a 72,000-square-foot concession mall and multiple exchange facilities.

Recent developments include the 2018 completion of the headquarters relocation from Seoul and the final stages of base expansion around 2020, which tripled the installation's size. In 2019, the Brian D. Allgood Army Community Hospital completed its transfer from Yongsan. A tour normalization policy introduced in 2010 extended service tours to two or three years to accommodate the increased presence of military families. The consolidation project moved the bulk of U.S. forces to regional hubs in Pyeongtaek and Daegu, positioning personnel approximately 60 miles from the Demilitarized Zone.
