In the second month of the Korean War, Eighth U.S. Army commander Lt. Gen. Walton H. Walker was faced by a severe shortage of strength and supplies along the Busan perimeter, and requested urgent backup from the Republic of Korea Army (ROKA), which was later answered on the 25th of July, 1950, by then-President of South Korea, Syngman Rhee, with the signing of an emergency decree directing ROK Army forces to provide civilian supply carriers to front line units. Eventually these carriers were organized into a centralized commanded battalion as the Civilian Transportation Corps (CTC) on March 15, 1951. Under the direction of General James Van Fleet, the CTC was later renamed to the Korean Service Corps (KSC) on July 14, 1951.[1][3]
In modern times, The KSC has become known as the KSC Battalion and its 17 companies continue to be part of the U.S Army operating within the Korean Peninsula.[3]
