It was built on the chassis of the Hispano-Suiza HS-30, which was also used on the Schützenpanzer SPz 12-3, and armed with twin French SS.11 antitank guided missile launchers. Only one of the missile launchers is visible from the outside at any time, however, as the other is retracted into the hull to be reloaded when the first is ready to fire.
