no he was still a commander
When he kills commander Cody.
of course Cody is a commander and rex is captain
you get commander Cody on the rishi moon, but you need seargeant fox and captain rex to unlock the station
the main ones are Captain Rex and Commander Cody
They both have the same rank. BUT commander BLY has more experience because commander Cody didnt participate in the first battle of geonosis and bluy did
Commander Cody gets killed by Genral Grevius.It is a part never ever shown in star wars.Obi Wan and Commander Cody went to fight Genral Grevius and Genral Grevius stabs Commander Cody.I found out from Leo Star Wars #1 That can't be canon because Commander Cody gives the order to shoot Obi Wan Kenobi when Order 66 comes in. Plenty of things get taken out, such as Shaak Ti's death in Episode III aboard General Greivous' ship. (I believe her canon death is during The Force Unleashed at the hands of the Apprentice).
captin rex
Captain commander Yamamoto or Genryusai shigekuni yamamoto.
no. commander Cody was so good he was assigned to obi won kenobi.
The 'commander', a term not normally used, of a British (not 'English'!) warship is known as the 'commanding officer' or 'captain'. In this sense, the term, 'captain', does not refer to his rank, as this may vary from lieutenant (e.g. minesweeper), lieutenant commander (e.g. conventional submarine), commander (e.g. nuclear submarine), or captain (e.g. aircraft carrier).The second in command is known as the 'First Lieutenant'. On large vessels, where the captain holds the rank of captain, the first lieutenant usually then holds the rank of commander, and is then known as 'the Commander' rather than 'First Lieutenant'.
A Commander is higher than a Captain in the Imperial Starfleet. This can be seen when a a Captain is given command of a Star Destroyer or Super Star Destroyer/ Star Dreadnought, while a Commander is assigned control of the Death Star II.
in the clone ranking system , commander is higher because capatains lead companies of 144 men and commanders lead battalions of 576 men.
