In 1964 Military Assistance Command, Vietnam, activated a joint unconventional task force known as the Studies and Observation Group--MACV-SOG. As a cover its mission was to conduct analysis of lessons learned in combat by all branches of service. SOG's real mission was to conduct covert strategic reconnaissance missions into Laos, Cambodia and South Vietnam as well as sabotage and 'Black' psychological operations. Ground, air and naval assets were employed to insert, collect, extract, and otherwise support these operations. This book tells the complete story of these covert agents, from their recruitment and training, through to their deadly black-ops in the jungles of Vietnam.
