- The United States military formally acquired the real estate comprising the Yongsan compound on September 11, 1948.
- Yongsan compound had previously served as the headquarters for the Japanese Governor-General and Imperial Japanese Army in Korea beginning in 1905 until 1945.
- In the mid-1950s, Yongsan became home to Headquarters, United Nations Command and Eighth Army. At the same time, the United States Forces Korea (USFK) Command was established at Yongsan. These commands remained at Yongsan until 2018, when they relocated to Camp Humphreys.
- Today, Yongsan supports several Camps and Sites geographically dispersed over the Greater Seoul area while undergoing transformation to eventual closure.
- The English translation of Yongsan is Dragon Hill.
- Prior to the establishment of the Installation Management Command (IMCOM), Major Commands such as Eighth Army in Korea, managed all Army Installations and Base Operations (BASOPS) services. When IMCOM became the Army’s single command responsible for worldwide installation management in 2006, organizations providing installation BASOPS services were redesignated as US Army Garrisons (USAG) and placed under IMCOM control.
- Under the reorganization, the Area II Support Activity at Yongsan was redesignated as USAG Yongsan and Area II, and the Area I Support Activity at Camp Red Cloud was redesignated as USAG Red Cloud and Area I. At Camp Casey, USAG Casey was formed, commanded by a LTC (O-5), and aligned under USAG Red Cloud and Area I as a subordinate (Indirect) garrison. At the time, Area I required a Direct and Indirect garrison structure to support BASOPS. This was due to the large Soldier population, robust training mission, and multiple camps and sites geographically disbursed throughout the area.
- In June 2018, USAG Red Cloud and Area I inactivated as part of the USFK Transformation and Relocation Plan, and USAG Casey was restructured and realigned as a subordinate (Indirect) garrison under USAG Yongsan and Area II.
- Today, the combined organization is referred to as USAG Yongsan-Casey, commanded by a COL (O-6) with a LTC (O-5) commanding USAG Casey. The organization continues to provide BASOPS support to camps and sites in both Areas I and II.
- Effective 1 March 2019, IMCOM realigned as a Major Subordinate Command (MSC) under the Army Materiel Command (AMC), in order to improve BASOPS support, services, and facilities to enable readiness and enhance the well-being of Soldiers, Civilians, and Families.
