The Imperial Tactical Manual detailed the strategies utilized by the Galactic Empire. L'ulo L'ampar, a Duros pilot, studied this manual and gained knowledge of Imperial combat methods. The manual prescribed that when the Empire had numerical superiority, they should focus their attacks on enemy vessels one at a time. During the Rebel Alliance's Starlight Squadron's ambush near Felucia in 3 ABY by Imperial Commander Ellian Zahra's forces, L'ampar observed that the TIE fighters were deviating from the manual's instructions for situations where Imperial forces had the advantage. Subsequently, he commented that the Imperial forces appeared to be corralling the rebels, preventing any possibility of escape.
