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.

"Every one of the personnel mentioned in SOG Kontum is a hero. The book also provides a list of medals/decorations awarded after some missions described, but the awards are only a footnote to the highly engaging narrative. The men of SOG-MACV fought for each other, not for the awards or glory." - On Point: The Journal of Army History

"This book is a very moving tribute to the heroism of the top-secret unit based on research and oral histories gathered from SOG veterans themselves. . . [A] powerful sense of sacrifice permeates the book and makes it profound and unique—especially when one considers the void of secrecy in which SOG existed." - Vietnam Magazine

"The format of the book works well. The move from one eyewitness account to the next is seamless . … [A] tribute to the SOG personnel and to the helicopter crews who risked their lives picking up endangered units" - The VVA Veteran
