This is an expansion to the Axis & Allies Miniatures War at Sea game system, sold as booster packs. Each pack includes five secret miniatures, with at least one rare unit. Set V, previously known as Fleet Command, includes 39 different units. Several new nations are included: Poland, Finland, and Sweden. Neutral Sweden comes with one predreadnought battleship, one cruiser and one destroyer. Sweden is assumed to be able to join either the Axis or the Allies. Other interesting units include the Japanese carrier Kaga, USN carrier Essex, German cruiser Blucher and Italian battleship Roma, as well as the Japanese hybrid battleship-carrier Ise and the converted British battlecruiser-to-carrier, Glorious.
