Depending on your source of information, France has been using the AMX-10RC since 1979 or 1981. One source says development began in 1970, with the first French unit getting its AMX-10RCs between 1981 and 1982.

I think it is strange that information on this armored car is so conflicting, and it is strange that I cannot find any images of in-service AMX-10RCs prior to Operation Desert Storm.
The RC stands for Roues-Canon, in English it means Wheeled-Cannon. It was made by a company called GIAT Industries (now called Nexter Systems).
