Notes: This is an 81mm mortar carrier based on the Japanese SU-60 armored personnel carrier. In this vehicle, the rear passenger area is taken up by ammunition racks and a turntable-mounted 81mm mortar. The glacis plate carries a bipod and baseplate for firing the mortar away from the vehicle. Only 18 of these vehicles were built. Ammunition racks for ready ammunition are few.

Notes: This is also a mortar carrier variant of the SU-60, this time mounting a 4.2" mortar. The bipod, bridge, and baseplate take up so much room on the glacis plate that the bow machinegun has been removed. Again, internal racks for ready ammunition are few and the vehicle often finds itself loaded with crates of ammunition. Only 18 of these vehicles were produced.
