The Collections and Security Division functioned as the military arm of the InterGalactic Banking Clan, incorporating both the Iotran Guard and the IG-series battle droid army. Command of this droid army was held by the Muun officer corps. Within the Cybloc system, the Banking Clan operated a transfer station that utilized spaceport police droids. As the Clone Wars began, San Hill pledged the Banking Clan's droid resources to Count Dooku and the Confederacy of Independent Systems, an agreement that was not exclusive to the Separatists. While the Security Division maintained some independent operations, demonstrated by defense droids within the Cybloc system, its military assets were largely integrated into the Separatist army. As an instance, Banking Clan droids fought alongside CIS forces in the Battle of Abrion Bridge. During the Outer Rim Sieges, forces combining Separatist and Banking Clan elements were entrenched on the planet Mygeeto.
