According to Wikipedia: "The MIM-72A/M48 Chaparral was a American self-propelled surface-to-air missile system based on the AIM-9 Sidewinder air-to-air missile system. The launcher is based on the M113 family of vehicles. It entered service with the United States Army in 1969 and was phased out between 1990 and 1998. It was intended to be used along with the M163 Vulcan Air Defense System, the Vulcan covering short-range short-time engagements, and the Chaparral for longer range use."
