Designed in 2680, the Thor was built to fill the need for quick artillery response on a fluid battlefield. Weighing in at 55 tons and with a speed of 81 kph, the wheeled vehicle was created to carry the Thumper artillery piece into battle.
         Though the Thor carries a respectable 7.5 tons of ferro-fibrous armor and has Cellular Ammunition Storage Equipment to guard against internal shell explosions, the vehicle relies primarily on its speed for defense. Though it cannot fire when moving, setting up its firing station requires less than 60 seconds, and the vehicle can be on the move again in under half a minute.
         The Thumper artillery piece, though light, has excellent range and a fast rate of fire. Groups of Thumpers have been known to level a city block in a matter of minutes. The tank's trans-optical aiming system, which links the spotter to the artillery piece, contains some of the most advanced communications equipment in existence.
         The Thor also sports twin Magna LT medium lasers in its turret, giving some resistance if the enemy comes too close. The lasers provide some defensive capability, but not in a prolonged engagement. The crew of a Thor has a better chance of surviving if they put some distance between themselves and the enemy, allowing them to use the longer-range Thumper.
         The Cellular Ammunition Storage Equipment provides excellent crew protection in case of an ammunition explosion. The shell storage compartment is lined with ferro-fibrous plating on five sides, which channels the explosion toward the sixth side if a chamber rupture occurs. The explosion blows out the rear armor and cripples the vehicle, but the crew of the Thor usually survives.
