Sprut anti-tank gun

2A45 Sprut-A, 2A45M Sprut-B and 2S25 Sprut-SD (Russian for Octopus or Kraken[1]) are the designations of the Soviet smoothbore 125 mm anti-tank gun.

The 2A45M was created in the late 1980s by the Petrov Design Bureau at Artillery Plant Number 9, which was also responsible for the 122 mm howitzer 2A18 (D-30).

A feature of the Sprut-B is its integrated engine, which can propel the gun on relatively flat surfaces (up to 15 degrees slope) and at 14 km/h on roads. This gives the gun a measure of mobility on the battlefield. It takes two minutes to go from firing position to travelling position and 90 seconds to go from travelling position to firing position. Such guns are known in Russian as "self-moving" as opposed to self-propelled, and outside of battle it is towed by an MT-LB.

The gun features a crew of seven. An OP4M-48A direct fire sight is used the day, while a 1PN53-1 night vision sight is used at night. For indirect fire, 2Ts33 iron sights are used, along with a PG-1m panoramic sight. The gun can reliably engage targets two metres high at a distance of 2000 metres.

The barrel features a thermal sleeve to prevent temperature changes affecting the accuracy. The gun uses the same split ammunition as the T-64, T-72, T-80 and T-90 tanks.

With the addition of the 9S53 laser fire-control system, the gun can fire laser guided projectiles such as the 9M119 Svir or 9K120 Refleks.
