British officers' Bath star rank badge

This badge, often known as a star or pip, was worn by British Army officers on the shoulder to denote their rank. This particular variety of star is called a Bath star, being a simplified version of the star of the Order of the Bath, one of the four British Orders of Chivalry. It features three crowns in the center, surrounded by the Order of the Bath's motto: "TRIA JUNCTA IN UNO", translating to "Three joined in one" in English. This is in turn flanked by two laurel branches, all overlaying a Maltese Cross.
