The Wookiee Army represented the military might of the Wookiee species' armed forces. Near the end of the Clone Wars, the Separatist invasion force posed a threat to Kashyyyk, the Wookiee's home planet. Consequently, the Galactic Republic's Grand Army dispatched a battalion of clone troopers, under the command of Jedi General Yoda, to bolster the Wookiee warriors during the Battle of Kashyyyk and reinforce the defense of their world during those late days.
