The GMZ tracked minelayer entered service in the mid-late 1960s. It is based on the SU-100P chassis, a prototype tank destroyer that never entered full production. It was fitted with infra-red driving lights, an NBC protection system, and could generate smoke by injecting diesel fuel into the exhaust. It had a 14.5mm KPVT heavy machine gun for self-defence.
Preparing the mines would take 15 to 40 minutes. Once this was done, the vehicle would be driven at a speed of up to 16km/hour if the mines were to be laid on top of the ground. If the mines were to be buried, it would drive at about 3km/hour. Mines would be fed onto trays on top of the vehicle. If the mines were to be buried, a plough would lift the ground. The mines would be automatically placed on the ground or inside the ploughed trough.
The GMZ-2 was an improved model. It had a more powerful engine, and allowed for different fuse types to be fitted to the mines.
