The leopards smaller brother
In the early 1960s, Bundeswehr decided to replace the aging M-41 walker bulldog from their reconnaissance battalions with a more modern and capable light tank. In a series of developments and requirements, Hanomag, co-producer of the JPz 4-5 series of tank destroyers, came through with the Ru-251 design. They built two prototypes with minor differences in 1963 and 1964.
The tank was designed to be able to deal with the then modern Soviet armour, so they used a BK-90 cannon, a license built German variant of the American M1 cannon. Unlike its American counterpart, the BK90 had access to a HESH round as well, however since it was a low pressure cannon, it was not cleared for use with armour piercing rounds, at least in German service as far as available information states.
The Ru-251 was built upon the chassis of the JPz 4-5 aswell, although it had one more roadwheel on each side, however it featured a cast rotating turret. the overall design was inspired not from the M48, as some deduce from the turret similarity, but from the German Europanzer prototype.
In game, this can be a tech tree light tank with an actual cannon that Germany so needs at 7.3.
Testing
The Ru-251 light tank underwent extensive field trials just as the leopard 1 was entering production. Even though the vehicle itself was promising, the Bundeswehr decided against it, arguing about the cost (to no ones surprise) of operating two more or less similar types of vehicles. They eventually substituted the M41 bulldog with the Leopard 1 in reconnaissance battalions instead of the purpose built Ru-251.

Extra info here
The main cannon, the BK90 is sometimes also called the Rheinmetall DM1, although i suspect it is more of a misnomer or a factory designation for the M1 cannon from the M48.
