| | A coat of arms is based on the shield and other weapons of the medieval knight. It consists of, at minimum, a shield, helm, and crest, and usually also includes some sort of decorative mantling around the helm. Optional elements include a motto, badges, and banners. Some elements, such as supporters, crowns, robes of estate, and so forth, are traditionally reserved for royalty and nobility. A full display of all the elements of a coat of arms is sometimes called a "heraldic achievement". | | A coat of arms is based on the shield and other weapons of the medieval knight.
