§ 494. Insignia for additional awards
No more than one medal of honor, distinguished service medal, distinguished flying cross, or one Coast Guard medal shall be issued to any one person; but for each succeeding deed or service sufficient to justify the awarding of a medal of honor, distinguished service medal, distinguished flying cross, or Coast Guard medal, the President may award a suitable emblem or insignia to be worn with the decoration and a corresponding rosette or other device.
