um... Russia has a LOT of usable T-34s.

and other advantages of smoothbore are the ability to fire APFSDS without special shells to reduce/eliminate spin, similar ability with HEAT rounds, as well as certain HE and fragmentation rounds which apparently aren't used with rifled barrels (not so sure about that stuff)
