The 2S25 is a Soviet light tank. It was introduced in Update "Direct Hit".

The 2S25 "Sprut-SD" is a modern entry in the long line of Soviet amphibious tanks started by the PT-76B. It uses the lightweight chassis of the BMD-3 airborne IFV, which offers a great power-to-weight ratio, a hydropneumatic suspension, and equal mobility in both forward and reverse at the cost of extremely light protection and a rather large profile. The oddly-shaped turret packs a full-size 125 mm gun with autoloader, giving the Sprut the same firepower as the T-72B. Using this vehicle effectively can be tricky because it is significantly easier to spot and destroy than contemporary Soviet MBTs while lacking access to thermal optics for easy target acquisition, so it's important to make the most out of the high mobility to ambush enemies and retreat from danger.
