Here are a few photos of the 10mm Soviet infantry I just finished, along with a few shots of the relevant infantry next to my prepainted 1/144 plastic Soviet tanks. They scale pretty well, all things considered.
(All captions refer to the photo below them.)
These are Pendraken 10mm infantry figs. I based 'em on 1x2-inch metal bases, four soldiers to a base. I could have done more, especially at 10mm, but I was trying to stretch my pool of figures and do more with less. I'm thrifty that way. To represent the somewhat haphazard way Soviet troops received their individual arms, I put one submachine gun trooper with three riflemen on each base. The rightmost stand has a DT machinegunner as well. The platoon commander is based separately up front.
This is a prepainted 1/144 KV-1 from the World Tank Museum line.
This is a T-34/85 from the same line. On the whole I'm very pleased with these prepainted models.
This is a T-34/76 from World Tank Museum, along with some Soviet infantry.
This is a prepainted SU-76 from the Axis & Allies Miniatures line. Most of their tanks and vehicles are closer to 1/120, as opposed to 1/144, but certain pieces (like this tank destroyer) scale pretty well.
This is a prepainted T-70 from my Axis & Allies Miniatures collection. Again, it scales pretty well despite not being designed for 10mm modeling.
