The 2S25 Sprut (Russian: Спрут; English: Octopus) is a light tank based on the BMD-3 chassis, but with a much larger 125mm smoothbore gun. It is meant to be a modern-day tank destroyer.
The 2S25 Sprut retains most of the features of its BMD-3 cousin and is meant for the Russian Airborne forces as a tank destroyer that can be airlifted into battle and move about quickly. The armor on the turret is made of welded aluminum with a composite skin to keep it light for airborne drops, but it retains the strength to be able to hold up against 23mm rounds from about 500 meters away.
Battlefield 2: Modern Combat
In Battlefield 2: Modern Combat, the 2S25 Sprut is used as the Middle Eastern Coalition's main battle tank. Despite being based upon a light tank, it has the armor equivalent of a main battle tank and its main gun can easily rip through enemy armor. The 2S25 only features a driver seat, who controls the vehicle and its main gun, making it the only tank in the game to not have a secondary gunner on top.
The Sprut-SD is seen in the screenshots and box art for the upcoming Battlefield 3 expansion pack, Armored Kill. It is a tank destroyer, meaning it has the armor and chassis of an IFV like the BMP-2M, but also carries a very large gun. That means that it is both fast and powerful, but in return has weak armor.
