SPRUT-SD
The 2S25 Sprut-SD is a self-propelled tank destroyer or light tank, built on the BMD-3 chassis. Designed for use by the Russia VDV airborne forces it is light and highly mobile.
The 125 mm 2S25 self-propelled anti-tank gun was developed by the Volgograd Tractor Plant Joint Stock Company to meet the requirements of the Russian Air Assault Divisions. According to the manufacturer, the 2S25 can also be employed as a light amphibious tank by rapid deployment forces, airborne, marine and special purpose units. In mid-2001, it was stated that the Volgograd Tractor Plant had been working on the 2S25 for about seven years. It was also stated that the 2S25, which is also referred to as the SPRUT-SD, could operate in the water and still be able to fire its 125 mm gun while afloat. It can also operate in altitudes of up to 3,000 m. The Volgograd Tractor Plant designed and manufactured the BMD-1, BMD-2, BMD-3 and latest BMD-4 airborne combat vehicles that are used by the Russian Air Assault Divisions. Recent information has indicated that production of the BMD-4 airborne combat vehicle has been transferred to the Kurgan Machine Construction Plant where production of the BMP-3 infantry fighting vehicle and its variants is currently undertaken for the home and export markets. As far as it is known, production of the 2S25 self-propelled anti-tank gun is still being carried out at the Volgograd Tractor plant.
The 2S25 is designed to be parachuted with the crew inside, allowing nearly immediate combat readiness upon landing. Each crewmember has their own day/night sight and the engine provides some 500HP. Republic of Korea and Indian military have expressed interest in acquiring the Sprut "Octopus" 2S25.
M1128
The M1128 Mobile Gun System is an eight-wheeled armored fighting vehicle mounting a 105 mm tank gun, based on the Canadian LAV III light-armored vehicle manufactured by General Dynamics Canada. It is in service with the United States and was also being considered for adoption by several other countries, including Canada.
The MGS turret is low profile, stabilized, and autoloading. The turret mounts a 105 mm M68A2 rifled cannon. The vehicle is primarily outfitted to support infantry combat operations. While it could take on some of the roles of tanks, it is not designed to engage in combat with tanks. The MGS can store 18 rounds of main gun ammunition in the turret. It has a rate of fire of six rounds per minute.
Because the Mobile Gun System uses a similar chassis as other MOWAG Piranha derivatives, it would have the same mobility, and could be rescued or salvaged by a Piranha-derived recovery vehicle.
Because the vehicle was designed without air conditioning, crews are given individual cooling vests that circulate cooled water from outside the vehicle to the garment. IV fluids can also be provided. Vehicle computers still overheat regularly.
