ths All-Terrain Open Transport was one of the first troop-carrying walker designs produced by Kuat Drive Yards, and it was the first that was specifically designed as a transport, rather than an assault vehicle (such as the AT-AT). The 14.3-meter-long AT-OT moved about on eight legs, and could accommodate up to thirty-four clone troopers in its open, flatbed body. More troopers could be piled onto the flatbed if needed, but the added weight sometimes caused problems with the vehicle's movement. The AT-OT stood sopme 5.8 meters in height, which offered some protection for the troopers riding atop it. Although designed purely as a transport, the AT-OT was armed with four laser cannons.
