Insignia

An insignia () is a sign or mark distinguishing a group, grade, rank, or function. It can be a symbol of personal power or that of an official group or governing body.

An insignia, which is typically made of metal or fabric, is a standalone symbol of a particular or general authority. Together, insignias form a decoration with the different elements of a rank, grade, or dignity.

There are many types of insignia, including civil and military decorations, crowns, emblems, and coats of arms. Provided by Wikipedia
