Terrex Titan

Terrex Titans (officially designated TP-GA, Terrestrial-Planet Ground-Assault.) and known by a plethora of nicknames such as White Walkers, Star Judges or World Walkers , were a type of enormous ground assault walker, and some of the largest planetary vehicles ever to be created. They were first conceptualized by the Galactic Empire, but only ever built by Darth Krayt's Sith Empire, and were used in several battles, including the Battle of Vitea. Terrex Titans had a humanoid shape and layout. They also stood one mile high, making them some of the largest vehicles ever to cross a planet's surface, and dwarfing anything the Galactic Empire had created.

Size and morphology
Although they shared some characteristics with walkers such as the AT-AT and the smaller AT-ST, Terrex Titans were really in class of their own. Firstly, they were on a much larger scale, standing a mile (1600m) high, making them comparable in size to star destroyers. Unlike smaller imperial walkers like AT-AT, that were mildly based on large alien animals, the structure of the walkers was based very strongly around a humanoid shape, hence they were bipedal, with arms free to move around and a "head" which housed the command center. The walkers were powered by solar ionization reactors similar to those that powered star destroyers, albeit only about 50% of the size. However, the walkers were far lighter than any star destroyer, and had no need to power sublight engines or repulsorlifts, and thus could divert an enormous amount of power to weapons system.

Mobility
Many of the motors and hydraulic systems in the Terrex Titans were mirrored in humanoid muscles, and despite the walkers' enormous size their movement strongly mimicked that of humanoid beings; the walkers were able to get down on all fours when conditions demanded it, and even stand up if they had been knocked over. Whilst bipedal, the walkers arms were able to clear any obstacles large enough to cause hinderance. The arm ends were equipped with various large scale landscaping tools, including rock saws, bucket wheels, suction mechanisms to disperse sand, grit or water and enormous flame jets to burn forests. The hands of the Terrex Titans also sported tractor beams

Armament
Terrex Titans sported almost as much weaponry as star destroyers, they were so powerful they could pose a threat to capital ships flying in the atmosphere, and even those in orbit. They also possessed weapons against fighters and aircraft, as well as against ground and water based forces. The walkers' arms themselves were incredibly powerful and able to move with great speed and accuracy, allowing the walker to grab on to enemy warships and and throw them off course, as well as to pick up large vehicles, weapons systems and buildings from the ground. Environment altering tools such as rock saws and flame throwers could and would often be used as weapons as well. In addition to these, the Terrex Titans sported a total of three octople barbette turbolaser systems, one on each hand and one in the head, as well as another 20 heavy turbolaser batteries, up to 40 regular turbolasers, 18 heavy ion cannons and 3 tractor beam projectors, one in each hand and one in the head.
