However, Warlaw is not a minatures game it's a hex and counter wargame. And incidentally lets you put a battle field on a relatively small sheet of paper next to your game.
If I were to use war law with miniatures I'd want to do 15mm or even 10mm and have stands representing whole units. Because a basic game unit is a hundred men and an advanced unit can be thousands.
Alternately you could find a copy of Legendary Battles by the Canadian Wargames Research Group, which is Warhammeresque and uses d10s. It's also very fast, simple and well balanced.
