Republic officers served both onboard capital ships and on the ground, directing both the Jedi Knights and the clone troopers under their command. Although they outranked all of the clones as birth-born enlisted personnel, the Republic officers were outranked by the members of the Jedi Order, the chief officers of the military such as Admiral Wullf Yularen and Captain Wilhuff Tarkin were superseded in authority only by Supreme Chancellor Palpatine.
