Epaulette (/ˈɛpəlɛt/; also spelled epaulet)[1] is a type of ornamental shoulder piece or decoration used as insignia of rank by armed forces and other organizations. Flexible metal epaulettes (usually made from brass) are referred to as shoulder scales.
In the French and other armies, epaulettes are also worn by all ranks of elite or ceremonial units when on parade. It may bear rank or other insignia, and should not be confused with a shoulder mark – also called a shoulder board, rank slide, or slip-on – a flat cloth sleeve worn on the shoulder strap of a uniform (although the two terms are often used interchangeably).[2]
