"The Grand Army of the Republic" is a title within the Star Wars Encyclopedia collection of reference materials released by De Agostini. Its release date was March 25, 2022.
The clandestine directive given to the genetic engineers of Kamino, tasking them with the creation of a clone army using the bounty hunter Jango Fett as the template, furnished the Republic with a military force capable of confronting the droid armies of the Confederacy of Independent Systems. However, despite being designed with uniform personalities and equipped with an inhibitor chip set to activate upon Palpatine's execution of Order 66, numerous clone troopers evolved unique identities and, in rare instances, even succeeded in removing their chips. Consequently, these soldiers did not betray the Jedi Generals they had fought alongside during the Clone Wars. A few even established autonomous units that essentially waged the war for their own purposes.
- On a particular page, Clone Captain Rex is incorrectly identified as a Clone Sergeant during the defense of Rishi Station.
- The encyclopedia claims that the Venator-class Star Destroyer Resolute was destroyed on the planet Maridun, when in reality a Consular-class cruiser was.
- Cody's designation of CC-2224 is occasionally written as CT-2224.
- The encyclopedia indicates that Captain Rex received his promotion to captain some weeks following the First Battle of Geonosis, even though he already held the rank of captain during that initial battle.
