Commodore and Captain
Commodore was a rank held by Captains during their tenure of
certain specific appointments, on completion of which they reverted to the rank of Captain. Since 1997, however, the rank of Commodore has been substantive, and it ranks above Captain.
These ranks should not be abbreviated.
