It consists of a heavily modified Praga Praga V3S six-wheel drive truck chassis, armed with a twin 30 mm AA autocannon mounted on the rear for which the vehicle typically carries 900 rounds of ammunition, each gun being gravity fed from distinctive 50 round magazines. The vehicle has an armoured cabin. In Czechoslovakia it was known as Praga PLDvK vz. 53/59 - "Ještěrka" (PLDvK Model 53/59 - "Lizard").[3] PLDvK stands for Protiletadlový dvojkanón = Anti-aircraft twin-gun. The system is optically aimed and can only be used effectively during the day with good weather conditions. The gun can be dismounted and used independently of the vehicle. While mostly obsolete in anti-aircraft role, it can be used effectively as a ground support weapon against unarmored or lightly armored targets, as was shown during the Yugoslav wars. It remains in service with armies of Egypt, Libya, Serbia, Slovakia etc. When Czechoslovakia imported one Soviet-made ZSU-57-2 for testing it considered it to be comparable to M53/59 which was the reason Czechoslovakia refused the Soviet SPAAG.[4] Operators
