Great looking force there old chap.
Love the rocketmen especially.
There do seem to be a lot of 'pointing chaps' though...'go west young man'?

The one thing that always seems missing from American VSF forces to me are cavalry - preferable riding 'steam horses'...hehe...

Really looking forward to seeing them on the battlefield.
As for rules, might i suggest
Rules of Engagement by Great Eascape Games? They are WWII platoon level actions (large skirmish) and i'm finding them simple, effective, intuitive and adaptable to many different settings.
