The Hồ Chí Minh trail (also known in Vietnam as the "Trường Sơn trail") was a logistical system that ran from the Democratic Republic of Vietnam (North Vietnam) to the Republic of Vietnam (South Vietnam) through the neighboring kingdoms of Laos and Cambodia. The system provided support, in the form of manpower and materiel, to the National Front for the Liberation of South Vietnam (called the Vietcong or "VC" by its opponents) and the People's Army of Vietnam (PAVN), or North Vietnamese Army, during the Vietnam War. It was named by the Americans after North Vietnamese president Hồ Chí Minh. Although the trail was mostly in Laos, the communists called it the Trường Sơn Strategic Supply Route, after the Vietnamese name for the Annamite Range mountains in central Vietnam. According to the United States National Security Agency's official history of the war, the Trail system was "one of the great achievements of military engineering of the 20th century."

Military Assistance Command, Vietnam – Studies and Observations Group (MACV-SOG) was a highly classified, multi-service United States special operations unit which conducted covert unconventional warfare operations prior to and during the Vietnam war. Established on 24 January 1964, the unit conducted strategic reconnaissance missions in Republic of Vietnam (South Vietnam), the Democratic Republic of Vietnam (North Vietnam), Laos, and Cambodia; carried out the capture of enemy prisoners, rescued downed pilots, and conducted rescue operations to retrieve prisoners of war throughout Southeast Asia; and conducted clandestine agent team activities and psychological operations. MACV-SOG participated in most of the significant campaigns of the Vietnam War, including the Gulf of Tonkin incident which precipitated American involvement, Operation Steel Tiger, Operation Tiger Hound, the Tet Offensive, Operation Commando Hunt, the Cambodian Campaign, Operation Lam Son 719, and the Easter Offensive. MACV-SOG was formally disbanded and replaced by the Strategic Technical Directorate Assistance Team 158 on 1 May 1972.
