When you look at accounts of the battle, the individual head-space of the corps commanders -- more the French than the German, but the German to some extent -- of the Corps commanders. This could be represented by making resolve a corps rather than a division attribute. It also could cut down on how much we represent?
Note Volley and Bayonet tracks hits by regiment, but exhaustion by division -- not that different a concept.
Note that, in the interest of keeping markers and labels to a minimum, I plan to denote which corps is which by the color of the tracking die. For the German, that might mean some added patterns -- probably matching that used on the epaulettes of the infantry of each corps. Since these dice are not for rolling, any effect paint might have on rolls is unimportant.
