Commander

"Commander" (中佐) is a military rank which is also sometimes used as a military title depending on the individual customs of a given military service. Commander is also used as a rank or title in some organizations outside of the military, particularly in police and law enforcement.

In One Piece, commander is a Marine rank just below that of a captain. Some pirate crews, such as Whitebeard's crew, are so big that they're divided into different divisions with a commander leading each one.

Whitebeard Pirate commanders:


 * 1st Division Commander: Marco (Marco The Pheonix)
 * 2nd Division Commander: Portgas D. Ace (Fire-Fist Ace)
 * 3rd Division Commander: Jozu (Diamond Jozu)
 * 4th Division Commander: Thatch (Deceased)
 * 5th Division Commander: Vista (Flower Sword Vista)
 * 13th Division Commander: Atomos (Water Buffalo Atomos)
