Battle Group Iota-4 was a Galactic Republic Navy unit within the 18th Sector Fleet. It was commanded by Admiral Enrit Falor and was made up of many Venator-class Star Destroyers, Acclamator-class assault ships, Arquitens-class light cruisers, and various other capital ships and starfighter squadrons, the exact number of which fluctuated throughout the Clone Wars. These vessels were capable of transporting several legions of clone troopers, including the 96th Legion. During the latter half of the Clone Wars, Battle Group Iota-4 played a major role in offensive operations against the Confederacy, especially the forces of Marshal General Yosip Zagoonga.
