Korean Military Advisory Group

The Korean Military Advisory Group (KMAG) was established by the United States in 1949 to assist in the creation, training, and organization of the Republic of Korea Army. Initially composed of a small number of U.S. officers and enlisted personnel, KMAG played a critical role in preparing South Korean forces prior to and during the Korean War (1950–1953). As the conflict intensified, KMAG expanded its mission, providing vital combat advice, logistical support, and coordination between United Nations forces and the South Korean military. By the end of the war, KMAG had grown significantly in size and effectiveness, leaving a lasting impact on the modernization and professionalization of South Korea’s armed forces.
