Commodore, a naval rank between that of captain and rear admiral. The U.S. Navy discontinued the rank in 1899 but reestablished it temporarily during World War II. The rank was reactivated in 1982, but in 1986 the name was changed to rear admiral lower half. An officer holding this rank corresponds to a brigadier (one-star) general in the army or air force.
