Pistoeka sabotage droids, better known simply as buzz droids, were a type of insect-like automatons that were deployed in swarms during battlefleet actions by the Confederacy of Independent Systems. They could wreak havoc upon squadrons of starfighters that happened to fly through a formation of such deployed droids. Approximately one-quarter of a meter in diameter and well armed for their role, they were typically delivered by discord missiles from droid tri-fighters and Vulture droid starfighters.
droids were intended to disable instead of destroy their targets. Since they were so effective when being deployed by tri-fighters, the CIS retrofitted a number of Vulture droids to carry them as well. The buzz droids also had simple maneuvering jets that helped them to move while still encased within their spheres. Once they came into contact with an enemy starship, they would use a magnetic pad to gain a foothold. The outer shell was coated with a heat dissipating alloy that allowed it to penetrate enemy shields; it was also constructed of shock-absorbing materials.
