Duel Moderne is a French set of miniature skirmish rules. The rules cover 6 time periods: colonial era, WWI, WWII, Viet-Nam war, present day, and sci-fi. The game scale is tactical (1 miniature represent 1 man or 1 vehicle, 1cm represent 1m and a turn represent 5 seconds) and uses simultaneous action resolution mechanics. There are rules for vehicles, morale, artillery, animals, and army lists with point values for each of the time periods covered.
