Established in March of 1979, the Commandant's Letter of Commendation Ribbon honors United States Coast Guard personnel who are presented with a letter of commendation from the Coast Guard Commandant. It may be awarded retroactively dating back to August 12, 1921.
The ribbon is bisected by a thick vertical turquoise stripe flanked on either side by a thin stripe of light blue, one of yellow, a thicker brown stripe, and green edging proceeding outward.
Subsequent awards may be indicated by service stars and the Operational Distinguishing Device when appropriate.
