The Sixteenth Army, alternatively referred to as the Ivory Fang Command, functioned as a Sector Army under both the Republic initially and the Imperial regime later, with its primary mission being the safeguarding of the Pallis Oversector.
Throughout the Clone Wars conflict, this army maintained a significant, albeit predominantly defensive, position within the command structure. Its responsibilities encompassed readiness for deployment towards the Core, bolstering defenses along the Corellian Run towards Corellia or the Rim, and shielding the Coreward Hydian Way and the Shipwrights' Trace from Separatist forces.
