In quick combat you will be able to select any number of scenarios or free flight. You can select season and weather, fly any plane that the service you are flying for used (central or allied). You will also be able to set the altitude, (field for takeoff), the number of wingmen and the type of plane you will fly against, skill level, and number of wingmen for each side.
