Flight officer was the lowest commissioned rank of the starfighter corps of the Rebel Alliance, the New Republic Defense Force, the Galactic Empire and the Galactic Alliance Defense Force. Its rank insignia for the Rebel Alliance pre-Battle of Hoth was a patch on the left shoulder, with the interior possessing a yellow bump in the center. It was similar to the rank of flight cadet pre-Battle of Hoth or cadet post-Battle of Hoth, albeit with a gold trim border. In the Rebel Alliance, it was either below the rank of Lieutenant or below Lieutenant Junior Grade. It corresponded to the naval rank of ensign.
