the thing is that the russian army runs on corruption. everyone is corrupt. everyone is stealing supplies. that's how the black market in western europe got flooded with assault rifles, rocket launchers, hand grenades, et cetera in the 90s. i even know a guy who used to be in the military (nato). when visiting russia as a tourist in the 90s he liked to visit military sites, which he was allowed to do for a small bribe. then he met with a local commander who offered to sell him anything (including tanks, so     's thing about tanks isn't far-fetched at all) for about 1/50th their official value as long as he paid in us dollars or german marks. i think you should be glad poland wasn't as rich and assertive as it is now, or poland would have 'magically' taken possession of half the russian army's tanks by 1991. and it's not changed that much since. like      says, russian officers are still stealing everything from fuel to entire tanks to sell on the black market. wherever the russian high command go, they find that the official numbers are massively exaggerated, because local officers have been selling all kinds of stuff off the books. i reckon that's also why russia has been buying artillery shells from north korea - the ones that russia officially had in storage were probably sold off the books to any number of african/middle eastern warlords in the 90s/00s/10s.
