The Unstable Terrain Artillery Transport (UT-AT), also known as the "Trident," was a military transport and assault vehicle that served the Grand Army of the Republic during the Clone Wars. It was developed by Kuat Drive Yards and Mekuun Corporation to provide a solution for crossing unstable terrain, snow, and water, where multi-legged walkers like the AT-TE struggled. Its defining feature is the two rows of sixteen repulsorlift skis that allow it to glide over difficult surfaces and even anchor to the ground for stable firing platforms. Known for being a "Trident" Tank, It earned that nickname from its three main forward-facing weapons: a primary mass driver cannon and two medium laser cannons. Some models were equipped with a bomblet generator capable of launching ion charges, useful for disabling battle droids and vehicles, or bridge-laying equipment, allowing them to create safe paths over chasms for other Republic vehicles. It typically carries a pilot, co-pilot, commander, and five gunners, with the capacity to transport up to 20 clone troopers or engineers in its front section. The repulsorlift skis, while providing excellent terrain adaptability, contributed to a low top speed. Its elevated position created a significant gap between the vehicle and the ground, making it vulnerable to well-placed explosives that could cause it to flip, leading to its destruction.
