The United States Forces Korea (USFK), often referred to as USAE, is a unified command of the U.S. Department of Defense established in 1950 during the Korean War. It primarily serves under the authority of the Commander of U.S. Forces Korea, who reports directly to both the President and Secretary of Defense of the United States. The USFK’s role is to ensure the defense of South Korea and maintain a strong presence in the region as part of the U.S.-South Korean alliance. The command consists primarily of U.S. Army units but also includes elements from the U.S. Navy, Air Force, and Marine Corps. The USFK’s mission is to deter aggression, support regional security, and protect South Korea and its people.
