The super tactical droid served the Confederacy of Independent Systems under Admiral Trench during the Battle of Anaxes. During the course of the Separatist campaign, Trench had been using a Republic strategy algorithm to gain the upper hand, using the Techno Union's test subject on Skako Minor, a captured ARC trooper "Echo."
The tactical droid was present alongside Trench aboard the Admiral's dreadnought Invulnerable, commanding the Confederate forces from above. Late in the campaign, the tactical droid informed Trench that the assembly plant has come under attack, only for the Harch Admiral to smile and remark that he would once again use the Republic's arrogance and desperation to his advantage. Unknown to them, the Invulnerable had been infiltrated by Jedi Knight Anakin Skywalker, Captain Rex, the newly-rescued Echo, and the Bad Batch. Still unaware of the recent events that had transpired on Skako Minor, Admiral Trench ordered the tactical droid to contact Skako Minor for Echo's algorithm. By this time, Echo and Tech had already intercepted the ship's interface unit and were able to mask Echo's transmission as originating from Skako Minor, fooling Trench. The tactical droid relayed Echo's algorithm, advising the Admiral to mobilize all troops to the assembly plant, claiming that the Republic would send all their reinforcements there due to their faith in the Jedi. The Admiral gloated and ordered the tactical droid to deploy more reinforcements to the assembly plant to crush all Republic forces with one strike.
As Confederate reinforcements arrived and overwhelmed both Generals Windu and Kenobi's forces, Echo then issued a pulse that shut down all of the Separatist droids. The tactical droid then informed the flabbergasted Trench that the source of the pulse originated onboard the dreadnought. Realizing that intruders were aboard his ship, Trench ordered the tactical droid to dispatch battle droids to locate them. The tactical droid then asked the Admiral on how they were to deal with their apparent defeat on Anaxes, Trench responded by switching to his own strategy, triggering the countdown on a bomb planted on the assembly plant's fusion reactor. Onboard, Echo interfaced with a computer to decipher the bomb's shutdown sequence, but the tactical droid was able to trace back the source of the pulse and jam the signal. Echo was electrocuted, rendering him unconscious before he could transmit the sequence to the Republic forces on Anaxes. Confident that his victory was assured, Trench ordered the tactical droid to send more troops to deal with the clone infiltrators and prepare landing craft for their next assault on Anaxes. As they were about to exit the command bridge, Trench and the tactical droid were shocked by the sudden arrival of Skywalker. The tactical droid prepared to fight, but Skywalker cut the droid down in seconds before killing Trench. They eventually destroyed the Invulnerable and the Battle of Anaxes ended in a Republic victory.
The tactical droid had green-painted armor with a red logo depicting Admiral Trench's likeness emblazoned on its chestplate.
The droid first appeared in "Unfinished Business," the fourth episode of the seventh season of Star Wars: The Clone Wars, which debuted on Disney+ on March 13, 2020.
