For the historical wargamer, a Norman army can be plausibly used in most any historical matchup set in the tenth and eleventh centuries. With their pioneering use of disciplined cavalry charges, they were highly sought after as mercenaries across Western Europe and the Near East. Unfortunately for their employers, Normans had a tendency to not remain contented with their role as hired swords and instead seek land and autonomy. By the end of the eleventh century, Norman kingdoms spanned the breadth of Europe and the Mediterranean, from England to Antioch.
