The Special Tactics Group 41-Delta, alternatively called the Bughunters or Bughunter Division, served within the reborn Sith Empire's Imperial military. Their focus was on missions targeting insectoid species, enabling them to execute extermination operations, hive removals, and the deployment of xenotoxic torpedoes. To match their specialized role, the team was equipped with chitin-penetrating ammunition and insecticide gas. This area of expertise made them highly effective against species like the Geonosians, Gands, and Verpines.
During the Cold War, the unit participated in actions against the Colicoids located on Balmorra, but they were subsequently redeployed to Alderaan. Their mission was to control the Killik infestation, ensuring that the Empire's allies in House Thul could operate without interference during the struggle for the Alderaanian throne. The Imperial Science Bureau supplied attractor technology, including the Brood Totem, to evaluate its potential in drawing Killiks toward enemy areas.
While calibrating their equipment, the group faced opposition from House Organa's soldiers and were poorly prepared for this engagement. Consequently, they assigned a special representative of the Empire the task of recovering the Totem from Killik territory and positioning it within House Organa's territory for evaluation.
