This is a set of World War II miniature rules from GHQ designed especially for their Micronauts (1:2400) naval miniatures line. All rolls use one d20.
Game Scale:
Surface ships: one model = one ship, 1 inch = 1000 yds/meters, 1 tactical turn = 6 minutes (in large scenarios, one hour strategic turns are used).
Motor Torpede Boat: 1 unit = 4 boats.
Submarine: one sub is represented by 6 markers; one true and 5 false (dummies).
Aircraft: 1 unit = 6 aircraft, a turn is divided into 6 impulses for movement/combat.
Aircraft enter a scenario already airborne. Takeoff/landing operations are not covered.
Nationalities included in the rulebook: US, British, Dutch, German, Japanese, and Italian. Free download Bonus Supplements add Soviet, French and many classes, including hypothetical ones.
Color game markers and combat table cards are also included. Get started with 10 ready-to-play historical scenarios set in the Atlantic, Mediterranean and Pacific.
You can also design your own scenarios with the (somewhat confused) scenario generation system.
