Bish, Knight, and Rook countries should have cruise ships converted for troop transport added to the maps with open water. They sail from friendly port to friendly port. They could be directed to follow simple command of traveling from lowest number port to the next higher number port. If a country has one port then they go into "cruise to nowhere" mode. If a country has no port, then no cruise ship.
This would be an added feature for open water strafing on enemy troop ships. Each cruise ship should be escorted by two destroyer escorts for defense.
