A description of how the rules work is available by clicking the link over top right, and there's a free downloadable resources pack in the Downloads section with printable markers if you need them, and some scenarios with typical force sizes so you can see what you're getting in to.
What I've tried to design is something that is truly an SCW wargame, and not "WW2 Lite", but is easy to learn and play. The rules boil down to a 2 page QRS at the back of the rules, and that's all you'll need once you've read the rules through. You'll need to keep the main rules handy for the first game or two, in case you need to cross check the fine detail (I've out in an index, too, to help out), but after that, you should find them simple and easy to play. Having said that, I think that the decisions you need to make mean this isn't always any easy game to win.
So, why not give something new a go?
