The Military Assistance Command, Vietnam Studies and Observations Group (MACV-SOG) was a highly classified, multi-service United States Special Forces unit which conducted covert unconventional warfare operations prior to and during the Vietnam War. The unit conducted strategic reconnaissance missions in South Vietnam, North Vietnam, Laos, and Cambodia; carried out the capture of enemy prisoners, rescued downed pilots, and conducted rescue operations to retrieve allied prisoners of war throughout Southeast Asia; and conducted clandestine agent team activities and psychological operations.

This book tells the story of the Teams operating out of FOB2 Kontum, near the tri-border area, in 1968–69. From recon missions over the fence to the heroic, and sometimes fatal efforts undertaken to try and rescue missing SOG members, the events are told through the words of the men themselves, supported by previously unreleased official documents.
