The Imperial Handbook: A Commander's Guide served as the official manual for the Galactic Empire's military forces, detailing strategies, branches, units, philosophy, and historical context. This guide encompassed details about the Imperial military, the navy, the stormtrooper corps, and the overall Imperial doctrine. It held significant importance for numerous Imperial commanders across the diverse branches of the Imperial Military. However, Emperor Palpatine noted in its conclusion that the book represented only a fraction of a commander's overall education. Despite its intended exclusivity for Imperial forces, Commander Luke Skywalker of the Rebel Alliance successfully acquired a copy half a year following the Battle of Endor. He then provided it to the Alliance Command, who subsequently added annotations to its various sections. Consequently, General [Carlist Rieekan](/article/carlist_rieekan/legends], a leading figure in the Alliance Command, devised a plan to diminish Imperial control in the Vorzyd sector by targeting deepdocks within the sector, leveraging insights gained from the handbook.
