Fifteen core modules provide representations of nearly every troop type, vehicle, and weapon to see combat action from any nationality involved in World War II. Each module comes with 6 to 20 researched situations depicting historical battles. These scenarios are printed on card stock with specifications of game length, map board configuration, counters involved, special rules for the conditions of the particular battle such as weather, and victory conditions. In addition to the scenarios published in the modules, there are numerous other sources for scenarios, both official and unofficial. There is also a detailed set of instructions in the ASL Rulebook for Design Your Own (DYO) scenarios based on a point-purchase system.
