The PLL-05 120mm self-propelled mortar-howitzer system is one of the ZSL-92 wheeled APC-mounted light artillery systems fielded by the PLA in recent years.The artillery system features a 120mm gun, which combines the features of the mortar and the howitzer. The artillery fires projectiles at both short-range, high-arcing ballistic trajectories (maximum 80°) and longer-range, less steep ballistic trajectories for indirect fire. 

      The PLL-05 uses a 6X6 wheeled chassis derived from the ZSL-92 APC. The combat weight is 16.5 tonnes, enabling the vehicle to be airlifted by a Y-8-sized transport aircraft. The vehicle is powered by a BF8L413F 4-stroke, 8-cylinder, turbo-charged, air-cooled diesel engine, which produces a standard power of 320hp. The vehicle is capable of a maximum speed of 85km/h on paved road and 8km/h when afloat. Two propellers are fitted at the rear of the vehicle for swimming.
