The TM-170 is based on Mercedes-Benz
Unimog chassis and components. The hull of the TM 170 is of all-welded steel providing protection from small arms fire and shell splinters. The vehicle is modular, and can be fitted with the following optional equipment: auxiliary heater, fire warning and extinguishing system, hydraulically operated 5,000 kg capacity winch with 40 m of 13 mm diameter cable, public address system, police flashing lights, radio, NBC filtering system and run-flat tyres. As well as the standard version a fully amphibious version was developed and marketed, but none are thought to have been sold. Armament on the TM-170 is optional and it is capable of being equipped with a pintle- or ring-mounted 7.62 mm machine gun, a turret armed with twin 7.62 mm MGs, or a turret armed with a 20 mm cannon. ==Operators by version==
