ENTAC ENTAC ( ENgin Téléguidé Anti - Char ) or MGM - 32A was a French MCLOS wire - guided Anti - tank missile . Developed in the early 1950s , the weapon entered service with the French army in 1957 . Production ended in 1974 after approximately 140 , 000 had been built . Development . The missile was developed by the French Government agency - DTAT ( " Direction Technique des Armements Terrestres " ) at the same time as the private industry SS . 10 Development time for the ENTAC was longer than the SS . 10 , so it did not enter service until 1957 . It proved to be a great improvement over the SS . 10 , which had entered production five years earlier . Once fully developed and tested , production of the ENTAC was given to the firm of Aerospatiale . The ENTAC was designed to be a man portable weapon or operated from a small vehicle like the Jeep , replacing the Nord SS . 10 in French service . Design . The missile is launched from a simple metal box , which is connected to an operator station . An individual operator station can control up to 10 launcher boxes . The operator manually steers the missile by means of a small joystick . These course corrections are transmitted to the missile via a thin set of wires that trail behind the missile - see MCLOS . Like many early ATGM s , the missile had a large minimum range ( see AT - 3 Sagger ) due to the time it took to get up to flight speed and come under operator control . Operational history .

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 . The missile was phased out between 1968 and 1969 , being replaced with the more advanced BGM - 71 TOW .
