Taisa

A Taisa is responsible for leading a large unit, such as a battleship or carrier, or for a group of smaller units such as a squadron of Plumeria Gunships. In order to become a Taisa, one must have a great deal of experience, including having previously served as a ship's executive officer. Below Taisa is Chusa, and above Taisa is Shôshô.
