Bear cavalry I think.
Who gets issued pistols in the Russian army, and what kind of pistols?
In Soviet Russian Army, yadda yadda..
To be clear the bears themselves are issued the sidearms...
I imagine that it is the same for generally every Army ever. Senior enlisted, Officers, specialized jobs where they may not always be able to carry a rifle, Military Police, Special Force types... As for the type of pistols, google Russian Pistols or Sidearms.
Also some generals have PSM. And Stechkin APS was produced for AFV, artillery crews and other such personnel. There is a new PYa pistol, that is intended to replace PMs, but it's still very buggy, and production rate is slow. Many MVD and FSB special forces personnel issued with Austrian Glocks as a standart sidearm. They also use the SPS/SR-1 Vector and several types of silenced pistols - PB, APB, PSS.
