Officer's disk

"You were saying, Administrator&hellip;''" "''Only that LaSal’s rank plaque insignia and command cap disk looked legitimate."

- Moff Wilhuff Tarkin and a Tanker administrator

An officer's disk, also known as an identity disk, was an identification device used by the military of the Galactic Empire. Those disks were placed on the command cap and belt buckle of Imperial officer's uniform. They took the form of a metallic stepped cone appearing to be three disks stacked on top of one another.
