The 2S25M is a Russian light tank. It was introduced in Update "Ground Breaking".

The 2S25M "Sprut-SDM1" is a modernized development of the previous 2S25 Sprut-SD and the capstone to the Soviet amphibious tank line. Although the external appearance is very similar, it is based on a revised BMD-4M chassis with the same engine and transmission as the BMP-3. Compared to the original Sprut, the 2S25M loses a significant amount of reverse speed and a small amount of horsepower, although the overall mobility remains good. The improvements are in the fire-control system, which now features thermal sights for both the gunner and commander and thus fixes one of the 2S25's original flaws. It also now has access to the powerful 3BM60 APFSDS round to better deal with contemporary tanks. Although the 2S25M has impressive offensive capabilities, it routinely faces modern MBTs such as the Leopard 2A4 and M1 Abrams that lessen or negate its mobility advantage. Thus, its playstyle demands even more caution.
