The U.S. Coast Guard Auxiliary also employs variants of the "title" of commodore. Members of the Auxiliary serve in the Coast Guard's uniformed auxiliary service and they do not have military rank, but who do wear modified U.S. Coast Guard uniforms and U.S. military-style officer rank insignia to indicate office. Auxiliary members who have been elected or appointed to positions in the highest levels of the organization, similar in nature to active and reserve rear admirals and vice admirals use the term commodore (e.g., district commodore, assistant national commodore, deputy national commodore, national commodore, etc.). These Coast Guard auxiliarists may permanently append the title commodore, sometimes abbreviated COMO, to their names (e.g., Commodore James A. Smith, National Commodore; or COMO Jim Smith, (NACO)).
