The division's original mission was the collection of debts and protection of IGBC facilities and personnel, but with the outbreak of war was quickly thrown into the front lines. Early in the war its forces fought independently under their own order of battle, however this method of fighting proved inefficient. Under the command of General Grievous, the Collections and Security Division was reorganized along with other droid armies into more effective fighting forces. It was deactivated, along with most of the CIS battle droids, when Darth Vader activated the master control signal after assassinating San Hill and the rest of the Separatist Council.

- Iotran Guard
Ground forces of the Collections and Security Division were divided into two groups. IG-100 MagnaGuards, because of their limited numbers, had no command structure. They simply followed the orders of whoever they were programmed to follow. Muun Guards and IG lancer combat droids both followed the same formation structure, although only Muuns were given command positions.
