During the Imperial Era, a TIE fighter patrol known as C-patrol was active. This patrol was made up of a pair of TIE fighter pilots who were assigned to patrol the planet of Agaris. Subsequently, one of the pilots received disciplinary action from an officer aboard the ISD Executrix due to an unsuitable remark. Later, this same pair of pilots engaged in the pursuit of the rebel operatives Lina and Milo Graf on the surface of Agaris.
