Used from 1964 until 1982.
The missile first entered service in 1957. The ENTAC may have been used by France in small numbers during the 1960s and 1970s on peacekeeping operations.
ENTAC missiles entered service in 1968 after being ordered a year prior. They may have been used against Pakistani tanks during the 1971 war.
Ordered in 1966 and delivered from 1966-1969. It remained in service after the 1979 Iranian revolution and was used against Iraqi tanks during the 1980-88 war.
Entered service in 1963 after being ordered the year before. It is likely that they were used during the 1967 Six-Day War against Arab tanks.
Ordered in 1966 and entered service in 1967. These were deployed during the Lebanon civil war and was used in street fighting, particularly during the early 1980s.
Having acquired some 500 examples in 1969, expeditionary units of the South African Defence Force first deployed ENTACs against Armed Forces for the Liberation of Angola (FAPLA) and Cuban military advisers during Operation Savannah. The system was often mounted on unarmoured Land Rovers. South African servicemen destroyed at least one FAPLA mortar position with their missiles in September 1975. Two Angolan T-54/55 tanks were also eliminated by ENTAC crews, working in concert with Eland and Ratel-90 armoured cars, during Operation Askari, 1984.
The US army purchased the Model 58 ENTAC with an improved warhead to replace the Nord SS.10 (or MGM-21A). It was designed to be an interim weapon, used as the BGM-71 TOW was being developed. The first missiles were deployed in 1963, that year the missile received the US designation MGM-32A. In US service the missile was based on the M151 Jeep and issued to the Anti-tank Platoon of the Heavy Weapons Company. In Korea (7th ID @ 1st CAV) it replaced the Scorpion tracked AT vehicle, a 90MM SP Gun which could not climb the hilly terrain as easily as the Jeep. Using extended cables missiles could be fired from defilade. The missile was phased out between 1968 and 1969, being replaced with the more advanced BGM-71 TOW. It was used in the Vietnam War against fortified infantry positions, but not enemy tanks. It was fired by the 14th Infantry Regiment, amongst others.
