David,
Whilst I agree that Russian/Soviet modellers, myself included, are increasingly well catered for I think you are speaking too soon when you say great kits of the T-72 and T-80. Out of all Russian MBT these are currently the most lacking in way of accurate models, although some holes are likely to be filled in the coming years.....probably primarily by Trumpeter who have filled/updated a lot of Russian armour lately.
In regards to "Soviet" figures (as opposed to post-1991 Russian), there are 3 decent mainstream (injection mold) sets available; Zvezda, Alanger & ICM representing late Cold War tank crews.
