Ship (unit type)
Ship is a unit classification. It consists of all naval units except Submarines. Ships can be hit by all weapons that ground units can, but generally need to be hit with specialized anti-naval weaponary (such as a Gunboat's missile or a Submarine's torpedo) to take significant damage. There are some exceptions to this - Bombers and Rockets both do high damage to land and sea targets. All ships are either of the Ship or Transport movement type.
