IIRC, missile troops lose their missile attack while underwater, and flyer may not fly underwater.

Piercer and the ethereal crossbow can stil fire underwater, and only aquatic and amphibian flyers can fly under water. Aquatic flyers given an amulet of the fish such as the Nerid retain their ability to fly when on dry land.
