The term 'uniform shoulder ornament' can refer to either an epaulet (7 letters) or an epaulette (9 letters). An epaulet is a flat, decorative piece of cloth or metal that is worn on the shoulder of a uniform. An epaulette is similar to an epaulet, but it is usually larger and more ornate. Both epaulets and epaulettes are used to signify rank or authority in the military, police, and other organizations.
