T - series tactical droid The T - series tactical droid was a model of tactical droid manufactured by Baktoid Combat Automata . They were used by the Confederacy of Independent Systems to coordinate their droid army during the Clone Wars . The T - series tactical droid played the role of war advisor as well as war general . The T - series was designed to create winning battle strategies throughout the earlier parts of the Clone Wars , later being replaced by the more advanced super tactical droid . They were very time - oriented , saying things like " … we have a schedule to keep " and " This is taking too long ! " . These droids were known to be arrogant and disrespectful , belittling those below themselves , and were even known to sacrifice a large number of their own troops for a victory . They also possessed a sense of self - preservation that was so strong that one T - series droid even left Separatist Council member Wat Tambor on Ryloth after the Republic Military captured the Lessu . This was also because Tambor had failed to follow a direct order from Count Dooku to evacuate the planet . This was another characteristic of the droids , although they tended to be selfish , they showed extreme loyalty to Dooku and the Confederacy of Independent Systems , even if they did not extend that loyalty to the generals under whom they served . The programming within these droids was severely flawed ; the overconfidence in the Droid Army of the Confederacy of Independent Systems , the slow processing of surprises from the enemy , and the inability to be flexible with seeing or using plans other than their own . They were more number - oriented than their successors , and relied much more on the feelings and thoughts of their victims to make a plan ; the T - Series Tactical Droids can be heard offering the probability of an event occurring to their commander / leadership . These droids were programmed with knowledge of Jedi tactics as well as individual Jedi and their profiles . This information became useful when TX - 20 utilized prisoners from a village on Ryloth as " living shields . " calculating that Jedi General Obi - Wan Kenobi would not risk the prisoners ' safety with a direct assault . History . At least three tactical droids were used by the Separatists during the Battle of Christophsis . Admiral Trench had the tactical droid TI - 99 aboard his command ship . The droid controlled shield usage and acted as a tactical advisor . Another tactical droid , TJ - 55 , commanded the Separatist ' s ground forces as they foiled the Republic ' s ambush , before it had its head stolen by Gus to discover how the CIS knew the Republic ' s strategies . Asajj Ventress later dispatched another tactical droid to give orders to General Whorm Loathsom while she left to continue her master ' s plan . On Naboo , one was used to carry out orders while Dr . Nuvo Vindi was planning to release the Blue Shadow Virus back into the galaxy . The droid used a Flitknot speeder to do scope out the area with three STAP - mounted B1 battle droids . His speeder was destroyed , and the droids ' remains were taken back to Theed so they could be scanned . This led to the discovery of Vindi ' s lab . Other notable droids were , TF - 1726 , the droid commander at the Battle of Quell , and TX - 21 , who served under Poggle the Lesser during the Second Battle of Geonosis at the Geonosis primary droid foundry . The droids continued to see use throughout the conflict , even until the Battle for Anaxes . Behind the scenes . The word ' tactical ' was written along the side of at least one tactical droid ' s head in Aurebesh .
