K33 Division functioned as a missile-centric combat entity within the CIS Army. This division played a significant combat role in both the initial First Battle of Geonosis and the wider conflict of the Clone Wars.
The K33 Division furnished a multitude of units fulfilling diverse functions. What distinguished it from other droid divisions was its utilization of droids equipped with advanced self-aware programming, coupled with enhanced artillery and torpedo systems, enabling them to overwhelm adversaries from a distance. The diverse array of unit types encompassed Persuader-class droids, Hailfire-class droids, and DSD1 dwarf spider droids which frequently operated in conjunction with the division's OG-9 homing spider droids. B1-Series battle droids piloted both AATs and STAPs during engagements to harass enemy forces. The collective synergy of these units resulted in a notably formidable fighting force.
The K33 Division deployed a specialized variant of the Hailfire droid, outfitted with potent artillery blasters and moderate defensive improvements. As the Clone Wars neared their conclusion, K33 Division also received tri-droids known for their capacity to dismantle both infantry and vehicles with relative ease. In preparation for the Battle of Kashyyyk, K33 augmented its forces with HMP gunships for their offensive on Kachirho.
