@UH : Oh, yes. IHMN provides rules to build your own companies. I plan to re-purpose my SMOG minis for this game as well. They are a perfect fit.
As for Dust 1947… if you don’t have the new dice, don’t bother. However, you might want to download some updated user-designed cards for the units. Very professionally done and won’t disgrace any of your battle videos, they are that good!
