Love that you used a D8 pool for this! Too many wargames stick to D6s. I have been kicking around with the idea of a D8 based skirmish game in my Miasma and Monsters system, so your game has inspired me to look at it again.
I love D8s, because they're basically D6 plus. It gives that little bit more wiggle for design space and stat spread which lets your strong guys feel that much stronger than your weak ones. I've never done a system with this kind of stat mechanic, which was pretty fun to work with.
