TA-175 is a T-series Tactical Droid serving as a commander in the Separatist Droid Army's forces on Ryloth and Wat Tambor's second-in-command. He is the secondary antagonist of the episode "Liberty on Ryloth".
Following the defeat of TX-20's forces in the city of Nabat, TA-175 advised Wat Tambor to retreat from Ryloth's capital, as the Republic forces would take it soon, but Tambor refused, wanting to collect the rest of the spoils he had acquired during his forces' occupation of the planet.
As the Republic forces pressed towards the city, TA-175 again advised Tambor to flee the planet, but his superior continued to ignore his advice, as two more tanks of riches were still delivering their stolen treasures.
However, these treasure tanks secretly contained Republic forces, allowing them to get inside the city. Deciding Tambor was a fool, TA-175 stole his superior's shuttle and fled the planet, leaving Tambor at the mercy of the Republic Clone Army.
