Notes: This vehicle is intended for fire support of infantry units, particularly Airborne and Naval Infantry units. It is essentially a BTR-D airborne combat vehicle topped with a large turret mounting a 120mm breech-loading mortar. The traverse of the turret is limited to 35 degrees left or right of center and the mortar may be fired in direct fire or indirect fire modes. The driver is in the front center of the vehicle with the commander to his left. The turret has a hatch for the gunner; this hatch sometimes has a weapon mount, but this is a rare modification. A modified form of the turret on the 2S9 is mounted on the BTR-80-based 2S23 mortar vehicle. As this vehicle was first produced in the early 1980s, there was time for sales to other countries, such as Afghanistan and Vietnam, but it was not widely sold.

Notes: This is a version of the BTR-80. The turret has been replaced with a turret mounting a 120mm breech-loading gun-mortar. There is a PKT (C) on the turret roof for anti-aircraft work. The firing ports have been deleted.

Notes: This is a 120mm mortar/howitzer vehicle based on the BMP-3 chassis. It fires mortar ammunition of either Bloc or NATO-compatible types. The standard turret is removed and replaced with a much larger one mounting the mortar/howitzer. The vehicle has an automatic survey and orientation system, and the vehicle can fire accurately without input from an FDC if the target location is known, within 7 minutes of a halt. The vehicle is equipped with all the sensors of the BMP-3 and also has a laser detection system that automatically launches smoke grenades in the direction of the enemy laser. The gun fires new ammunition as well as the ammunition of the 2S9 and 2S23 and ammunition of Western make. The vehicle also has the singular luxury in a combat zone of a chemical toilet inside the vehicle. The commander's machinegun may be aimed and fired from under armor. The roof hatches have been removed, and the rear hatches are replaced with a single downward-opening hatch on the left rear. There is also a hatch in the rear of the turret for ammunition loading. There is a commander's hatch in the turret.

Twilight 2000 Notes: This vehicle does not exist.

Merc 2000 Notes: This vehicle did not fare well in the budget-conscious Merc 2000 Russia.

Notes: This is a rather common mortar vehicle in Pact and Russian service, though in Russian service it is primarily found in Category 3 and Mobilization-Only units. It is an MT-LB armored personnel carrier with an 82mm or 120mm Pact mortar mounted in the passenger area (the exact type depends on the country of service). In the 82mm mortar carrier, the rear deck has a two-part circular hatch for the mortar to fire out of, while in the 120mm version, the hatch is two part, long, and rectangular. In both cases, bipods and baseplates are carried so that the mortar may be fired away from the vehicle. The vehicles retain their cupola-mounted machineguns. The large MT-LB chassis can carry a lot of ammunition for the mortars.

Notes: These heavy self-propelled mortars have been in service with the Russian Army since 1975, and later with Iraq and Lebanon. The chassis is a modified version of the chassis used for the SA-4 SAM. The driver is seated to the front left, the driver in front and commander behind him in a cupola with a machinegun. The two other crewmen are seated in the rear. (Five other crewmen are transported in another vehicle). The 2B8 mortar is carried over the deck of the vehicle when traveling and is lowered to the rear before firing. The mortar is breech-loaded from two 20-round magazines by an automatic loader. The SM-240 is normally an asset at regimental and higher levels. The SM-240 is perhaps the only mortar in existence capable of firing tactical nuclear ammunition.
