The M48 Chaparral is an American-made self-propelled surface-to-air missile based on the M113 family of vehicles. The MIM-72 missile is based on the AIM-9 Sidewinder air-to-air missile system. The M48 entered service with the United States Army in 1969 and was phased out as the M48A2 between 1990 and 1998. It was intended to be used along with the M163 VADS, the Vulcan ADS covering short-range short-time engagements, and the Chaparral for longer range use
