Fantasy WW2 from the GW school of thinking, rules play quite well, and there is a lot of support material out there, you either love the rules. or hate them with a passion.
You can however field Ubersturmbahnfuhrer Wnkelhoffs SS assault unit complete with gung ho heroes and special weapons, if you like that sort of thing.
Its the rules that Glen Brooks and Percy used to play at Coltishall before they moved to New Buckenham.
