History:
Development of the XR311 commenced as a private venture in 1969 with the first of two prototypes being completed in 1970. As a result of the trials of these 2 prototypes the United States Army purchased 10 improved or second generation models in 1971. Of these 10 vehicles, 4 had TOW missile installation for use in the anti-tank role, 3 had a .50 cal (12.7 mm) machine-gun for use in the reconnaissance role and 3 had 7.62 mm machine-guns and the crew armor kit for use in the escort/security role. These trials were completed in 1972. They were then tested by the 2nd Armored Division. In 1974 they were also tested in the 2nd Armored Reconnaissance Scout Vehicle competition along with a number of vehicles. The FMC XR-311 was built in three basic evolutions, the early square headlight model, of which just one or two were made in 1969-70, the so-called "shrouded headlight" version made till 1974 and the last type, made to at least 1978. The latter had a slightly different front end and open headlights protected by guards. Of the last two types, an unknown but fairly large number were made. There are indications that as many as 16 were built.
