635th Combat Support Group

• Origins: The 635th Combat Support Group was first activated during the Vietnam War era to provide vital base support for United States Air Force operations in Southeast Asia. • Location: The group was assigned to U-Tapao Royal Thai Navy Airfield in Thailand, a strategic base for B-52 and KC-135 operations. • Support Role: The 635th was responsible for all base operations, including security, civil engineering, logistics, medical services, and administration for personnel stationed at U-Tapao. • Vietnam War Contributions: The group supported the large-scale bombing campaigns, including Operation Linebacker II, by ensuring the aircrews and aircraft had the necessary support and infrastructure. • Critical Infrastructure: The 635th managed and maintained the runways, fuel storage facilities, munitions storage, and living quarters for thousands of U.S. and allied personnel. • Humanitarian Missions: In addition to combat operations, the group also assisted with humanitarian relief efforts in Southeast Asia, providing aid and logistics after natural disasters. • Secrecy and Security: Due to the sensitive nature of B-52 bombing missions, the 635th maintained high levels of operational security and frequently coordinated with Thai authorities. • Inactivation: The 635th Combat Support Group was inactivated in the mid-1970s as U.S. operations in Vietnam wound down and American forces withdrew from Thailand. • Legacy: Many veterans who served with the 635th have maintained connections through reunions and veterans’ organizations, preserving the group’s unique legacy. • Decorations: The group and its subordinate units received multiple commendations for their service, including Air Force Outstanding Unit Awards for their exceptional support during critical combat operations.
