Tactical drone

A tactical drone was a type of drone utilized in the Borg Collective, some of which possessed a tritanium infrastructure.

During their expedition to locate and study the Borg in the early 2350s, the Hansens managed to beam a tactical drone onto the USS Raven for examination. They determined it's species was Ktarian, known to the Borg as Species 6961. 

Hazari also made excellent tactical drones due to their violent nature and advanced technical abilities.
