The 2S25 is a self-propelled anti-tank armored vehicle developed and manufactured by the Russian Defense Company Volgograd Tractor Plant Joint Stock Company to meet the requirements of the Russian airborne troops. In mid-2001, Volgograd Tractor Plant started the development of the 2S25, this one lasted several years. The 2S25 is also known under the denomination of Sprut-SD. The 2S25 Sprut-SD is designed to defeat tanks, hard-skinned materiel and enemy manpower by airborne and amphibious landing forces, as well as by special-designate units of ground forces. The 2S25 is an armored tracked amphibious vehicle as powerful as T-72 and T-80 tanks and as maneuverable and swim-capable as airborne infantry combat vehicles. The 2S25 Sprut-SD can be used by units of ground forces and naval infantry as a light amphibious tank. The 2S25 Sprut-SD is based on the BMD-3 chassis. According to Russian information, the Russian Army placed an initial contract for a total of 15 2S25 SPATG in three batches of five vehicles each in 2005. This was followed by a second batch of 45 units with the total requirement being for up to 85-110 units.

|Design and protection|
The hull and turret of the 2S25 self-propelled anti-tank gun are of all-welded aluminum armor with a composite skin. Constructed with the crew compartment at the front, turret and fighting compartment in the center, and power pack at the rear. Through the frontal arc of 40° left and right the armour provides protection against attack from fire up to 75 mm and through the remainder of the vehicle against attack from 30 mm.
|The suspension of the 2S25 Sprut-SD on either side consists of seven single road wheels with the idler at the front, the drive sprocket at the rear, and six-track return rollers. The 2S25 Sprut-SD is motorized with a VV06-2S Diesel engine with a power of 510 Hp. The 2S25 Sprut-SD has a maximum road speed of 70 km/h and a maximum road range of 500 km. The 2S25 Sprut-SD is fully amphibious and is moved in the water with the aid of two water jets, which makes it possible for it to develop a speed 8-10 km/h.|
|The 2S25 Sprut-SD antitank gun can be shipped by all types of transport, para-dropped with the crew inside the vehicle and cross water obstacles in a sea state of up to-3 without preparation while firing the gun within a sector of ±35. To ensure concealment, the ground clearance can be changed within 400mm during 6-7s. Each member of crew has available the built-in roof observant instruments with the day and night channels. The combined sight of the commander is stabilized in two planes and is combined with the laser sight for guiding 125-mm projectiles along the laser beam. The sight of the spotter is stabilized in the vertical plane and includes the laser range finder, which provides a ballistic calculator with constantly changing data about the purpose.|
