The final version of the BMP-series, the BMP-3 is out righteous worthy of being called a light tank. It mounts a 90mm cannon, a 30mm auto cannon, and 12.7mm MG. The entire BMP series is capable of being in the water, so there isn't a huge need for water capable craft to carry the Russian army across rivers and lakes. The BMP-3 will be a force to reckon with.
