The UA-TT could deploy its CAP-5 captivator arm for stabilized firing. Such designs dated back to the Clone Wars-era AT-AP walkers used by the Galactic Republic. The limb could also be used to grab enemies hiding in bulidings usings its claws. In order to use heavy machinery in an urban area, the First Order deployed UA-TT walkers as opposed to the larger, heavier AT-M6 walkers. This was done so the city in question would not be destroyed during occupation.
In 35 ABY, during the First Order-Resistance War, at least one was deployed on Kijimi.
The UA-TT appears in the 2019 sequel trilogy film, Star Wars: Episode IX The Rise of Skywalker.
