H-Eta Squadron was a component of the Imperial Navy that flew TIE/sa bombers throughout the Galactic Civil War. This unit was a part of a fleet that was under the leadership of Admiral Harkov. The squadron also switched allegiances when Harkov deserted to the Alliance to Restore the Republic in 3 ABY. During the Battle of Ottega, the squadron engaged in combat against the Galactic Empire, ultimately resulting in its complete annihilation.
