The tactical map is a generic blue field of hexagons, used to resolve surface combat. There, ships maneuver and fight using their gunnery and torpedo factors. Each player rolls a number of dice according to the ship's capabilities, hitting on a result of 6. Gunnery and torpedo damage tables give the results: ships can suffer damage to engines, hull or armament. Air attacks are resolved in similar fashion. The combat systems yield results rapidly but in a historically accurate fashion, giving a good balance of fun and insight.
