The Operational Distinguishing Device ("O" device) is a miniature silver inch letter "O" that is authorized by the United States Coast Guard as a ribbon device which may be authorized for wear on certain awards and decorations of the United States Coast Guard.
The "O" device is either centered on the suspension and service ribbon of the medal or unit award ribbon, or to the middle-right if there are an even number of letter devices on the ribbon. Any authorized gold Inch Stars alternate around the "O" device. The first star is placed to the wearer’s right of the "O" device and the second star is placed to wearer's left of the "O" device. Only one "O" device may be worn per ribbon.
