Notes: This older Czech self-propelled antiaircraft gun is mounted on an armored and much-modified Praga V3S truck (see Czech Medium Unarmored Vehicles). The guns are fed from vertical magazines holding 50 rounds for each gun. The entire gun platform can be removed and deployed away from the carrier vehicle, but this was not normally done unless the vehicle was damaged beyond moving. The M-53-59 is a clear weather system, as no radar or night vision equipment is provided. This vehicle is used by Czech reserve forces, Yugoslavia, and Libya.
