The All Terrain Reconnaissance Transport (AT-RT), also known as the All Terrain Recon Transport or the Republic scout walker, was a model of recon walker manufactured by Kuat Drive Yards which saw extensive use during the Clone Wars by Advanced Recon Force Scout Troopers of the Galactic Republic. It was the precursor to both the All Terrain Defense Pod and the All Terrain Scout Transport. During the Galactic Civil War, these walkers were adopted by both the Galactic Empire, who used Scout troopers to man the vehicles, and the Alliance to Restore the Republic, who upgraded them to compete with the advancements of the Empire.
The AT-RT’s were usually used for a variety of missions including ground support, police support, civil defense, and post-battle cleanup efforts. They occasionally took up position on the front lines of ground battles when difficult terrain prevented the use of larger vehicles.
Advanced Recon Force Scout Troopers, also referred to as Advanced Recon Force troopers, ARF troopers, or as AT-RT Drivers, were clone troopers who wore lighter armor for stealth and speed and often rode All Terrain Reconnaissance Transports into battle, wielding RPC-2 Rocket Launchers and DC-15A blaster rifles. They were more intelligent and better trained in survival skills in comparison to other clones.
