Notes: Developed by the Swiss as a private venture for export, the ADATS was adopted by the US Army and Canada as a heavy tactical missile for both air defense and antitank use (hence the name ADATS). Development continued by the Canadians, resulting in both the present-day ADATS missile and the M-113-based ADATS vehicle. The shelter-mounted version may be placed on the ground or on the back of a truck with at least a 5-ton capacity; the radar is carried on a separate vehicle. So far, the only country using the shelter-mounted ADATS is Thailand, and they use a Skyguard radar system for fire direction. Antiaircraft statistics are given below.

Twilight 2000 Notes: At least 300 of these units were deployed in Alaska and Western Canada by US and Canadian forces.

Merc 2000 Notes: This system, especially when mounted on a truck, has proven to be a popular lower-cost alternative to the M-113-based ADATS vehicle.
