The real interesting aspects will be new AFV and weapons: M46's, Centurion III's (!), 3.5" Bazookas, and M19 twin Bofors(!!). Along with that, you'll have Jet Age air support. American and British infantry likely would go unchanged. It will be interesting to see how they handle the Koreans (both sides) and the PLA - plus Greeks and Turks, oh my!
