World thrasher

World thrasher was a massive armored vehicle developed by the Eternal Empire of Zakuul. Capable of uprooting or incinerating trees, smashing boulders, flattening hills, and even burrowing through mountains, World Thrashers were used to clear a path for incoming ground troops during the planetary invasion. Though slow and ponderous, they were nevertheless extremely effective at their job. A large number of World Trashers were deployed during the Assault on Odessen in 3631 BBY.
