As for the Zvezda plastic tankers they are very good figures and a real improvement on recent Zvezda figures. Actually I also have Zvezda's Vympel unit box set, and the anatomy and posing on the Tankers is far superior. The poses are very life like and match the reference photo very well. One really nice feature is the separate fur collars, and the tank helmets made up of three parts. The extra parts for the helmet really add to the depth of the heads and faces and is much better than a one piece casting I think. I'd recommend them for sure.
One only problem is that some of the detail is a bit soft. For example the faces could do with a little sharper detail, the fur collars are quite soft, and the jacket details need a little refinement.
On mine I added detail to the fur collars with some Mr Surfacer 500 and a little stippling. I also improved the jacket detail by adding plasticard strips to the pocket detail to make it stand out a little more. I also reposed the figures and did some work there re-sculpting the anatomy and using filler. I also added replacement resin hands and heads from Hornet. I still used the plastic Zvedza tank helmets, these took a little work as the Zvezda heads have the top of the helmet cast into the head, so I had to chop that off and hollow them out so they would fit onto the Hornet heads. I then had to add the separate side sections and fill the gaps with filler.
One thing to watch out for is the "creases" in the plastic where they haven't cast fully. These are easily filled and covered with a bit of filler though. Here are the two tankers that I will be using on my T-80:
