 Specific mission responsibilities are accomplished through the group's four squadrons, six detachments, and the Program Management Office.The group was first organized as the 1879th Communications Squadron during the Vietnam War in 1965.In 1971, as American participation in the Vietnam War was reduced and United States Air Force closed down its activities at Nha Trang Air Base, the squadron was moved to Richards-Gebaur Air Force Base, Missouri, where it absorbed the mission, personnel and equipment of the 2009th Communications Squadron, which was inactivated.
