A colonel of the Imperial Army, a male serving the Galactic Empire, was stationed on the Mid Rim planet of Haidoral Prime. This occurred during the Galactic Civil War, when the Empire was battling the Rebel Alliance. He conducted his duties from the Governor's mansion. In 3 ABY, First Sergeant Hazram Namir led three rebel soldiers to infiltrate the mansion. While looking for supposed prisoners, they unexpectedly found the colonel and his officers. The colonel went to grab a weapon, but halted when Namir pointed his blaster rifle at him, inquiring about the captives. The colonel seemed baffled by the question, until Everi Chalis, Haidoral's governor, exposed herself and fatally shot the colonel. She then assisted the rebels in eliminating the other officers present. Following this, Chalis joined Namir's unit, the 61st Mobile Infantry.
Alexander Freed's 2015 novel, Battlefront: Twilight Company, featured an appearance by a colonel.
