I've decided to go with 20x10mm bases, minimal flocking and a colored label at the bottom, explaining what the unit is.
The Russians look good already. What I need to do now is choose a color scheme for the Germans' labels.
I'm looking for a mix of legibility and attractiveness. Please tell me which scheme you think is the best. Top panzer is #1 and bootm panzer is #5. (Note that #5 panzer still needs to be flocked.)
