Because they're old rust-buckets that are only good as supplies of replacement parts for the tanks that still work. Have you seen that smoking aircraft carrier? Russian military equipment is often in a terrible state. Of course they also have this brand new super tank, the T-14 Armata. No idea why they're not fielding that one, but I suspect it doesn't work.
