Commodore admiral
Commodore admiral (COMO) was a short-lived military rank of the United States Navy and United States Coast Guard that existed for less than 11 months during the year 1982. The rank of commodore admiral was established as the Navy's one-star admiral rank after nearly forty years of all Navy and Coast Guard captains receiving promotion directly to the two-star position of rear admiral, but still being paid as a one-star officer in the pay grade of O-7 while in a "rear admiral, lower half" category.
