In heraldry the term mullet or molet refers to a charge or a difference in the conventional shape of a star, by default one with five points (compare pentagram), though in early armory the same coat of arms might appear with mullets of five or six points. When a number of points other than five is specified, the points are typically much more acute than those of the star of David or octagram. The arms of the 240th Signal Battalion of the United States Army show a mullet barbed to chief. (See The Institute of Heraldry's article on the 240th Signal Battalion.) Under the English cadency system third sons bear the mullet as a difference. The mullet is called a star in Scottish heraldry. It is to be distinguished from the wavy-rayed estoile.
