Officer's disk

An identity disk, also referred to as an officer's disk, served as a means of identification for Galactic Republic navy officers and Clone navigation officers, and subsequently for the Galactic Empire's military. These disks were affixed to the command cap and belt buckle of the uniform worn by Imperial officers. Their design consisted of a metallic cone with tiered steps, resembling three disks stacked vertically. The Sith Eternal also incorporated officer's disks into their own uniforms, which were inspired by the Imperial style.
