(especially Stalingrad and partisan warfare) ..........at the company/platoon level at the Eastern Front, so that I'll buy the right miniatures.
i'd suggest you field what you want - units never went into battle with the correct TOE, and by Stalingrad units strengths were all over the place, equipment varied, and included captured weaponry, so unless you want to place a competition game...{shudder}....i'd suggest you buy whatever catches your eye, and split it into 3 or 4 squads a platoon, with a command section, and replicate at Company level - Soviets will, on the whole, have less officers, and generally larger units, but with less support weaponry.
