You mean, does NA have units thta look OK with sets 1 through 5?
Well, all the infantry (the US and Russians finally get an MG), all the artillery (and there is a LOT of new cool artilley) and all of the planes are fine. As for vehicles, it’ll be a minority so you’d want to trade away most.
I think most if not all of the arnoured cars would be OK. The Italian Autoblinda is a great unit stats-wise. The Germans get a Jeep (the Kublewagon) that would be OK. Same for the Motorcycle half-track. I think even some of the assualt guns (like the Wespe) would be acceptable, as I recall the sIG was pretty big to start with.
I haven’t laid them all side-by-side, but I’ll se what I can do and maybe take a picture or something.
