I managed to do a bit more work on my 28mm WWII Soviet figures this evening. I suspect that trying to paint 40+ infantry in one go was probably a bad idea and I will, in the future work on single squads and teams. The painting in large batches is a holdover from my past when I was able to sit and paint for more than 30 minutes at a time and its not really appropriate to my current situation.
Once the infantry are done I suspect that I will attempt to do a squad of late war German troops and then add some individual gun teams for each force. I have several Soviet teams assembled and primed and I have some 28mm Bolt Action and Artizan WWII Germans on order to expand the German force.
