The 2S25 is an armoured tracked amphibious vehicle as powerful as T-72 and T-80 tanks and as manoeuvrable 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.

The 2S25 Sprut-SD is fully amphibious and is moved in the water with the aid of two water jets, which make possible for it to develop 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 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 the 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 spotter is stabilized in the vertical plane and includes the laser range-finder, which provides ballistic calculator with the constantly changing data about the purpose.|
