100 dice!! I think you may have reached overkill levels of dice-throwing already :) Here’s my suggested breakdown:
20 “ones” 40 “twos” 30 “threes” 10 “fours”This would represent a perfectly-matched battle with a unit count of 40-50 and the following composition on each side:
20 inf/art in any combination 15 tnk/ftr 5 bmrI think that breakdown would cover 95% of your battles, with a possibility that you have to throw some infantry dice twice (or throw a few of them into a “2x” or “3x” tray).
