This annotated reference map traces the geography of MACV-SOG's covert cross-border operations along the Laos/Vietnam frontier, including the Ho Chi Minh Trail's mountain passes, the NVA's 'Oscar Eight' logistics headquarters, and the Bolovens Plateau - the setting for Operation Tailwind in 1970. Maps like this helped planners and, later, historians visualize the remote and rugged terrain in which Special Operations and Studies and Observations Group teams conducted some of the war's most secretive missions.
