Camp Humphreys (), also known as United States Army Garrison-Humphreys (USAG-H), is a United States Army garrison located near Anjeong-ri and Pyeongtaek metropolitan areas in South Korea. Camp Humphreys is home to Desiderio Army Airfield, the busiest U.S. Army airfield in Asia, with an runway. In addition to the airfield, there are several U.S. Army direct support, transportation, and tactical units located there, including the Combat Aviation Brigade, 2nd Infantry Division. The garrison has an area of and cost US$11 billion. Camp Humphreys is the largest U.S. overseas military base, housing some 500 buildings and amenities. In 2004, an agreement was reached between the United States and South Korean governments to move all U.S. forces to garrisons south of the Han River and relocate the United States Forces Korea and United Nations Command Headquarters to Camp Humphreys. Those movements were completed in 2018, and transformed Camp Humphreys into the largest U.S. Army garrison in Asia. Under that plan, the 28,500 U.S. troop presence in South Korea was consolidated and United States Forces Korea moved from Yongsan Garrison in Seoul to Camp Humphreys. Camp Humphreys is south of the former base in Seoul and about from the Demilitarized Zone that divides North and South Korea. That puts the base about twice as far from North Korea as its predecessor, one of the main reasons for the move. While the new location moves the bulk of U.S. troops out of the range of North Korean artillery, the North Korean military has developed large caliber rockets and ballistic missiles, as well as a nuclear capability, capable of reaching Camp Humphreys.
