Marauder Tank

Marauders, also known as Enforcers are massive four-legged tanks which stride across the battlefield before assuming a more stable posture in order to fire. Their main armament is an array of mortar launchers mounted atop their hulls, which can bombard enemy emplacements, swiftly reducing them to ruin. However they are also equipped with a shorter range continuous beam to deter any attackers foolish enough to get close.

Transformers: Fall of Cybertron
In the closing days of the Great War between the Autobots and Decepticons, Marauders came into use. The Decepticons brought many with them when they assaulted the Ark in an attempt to prevent its launch. Optimus Prime found heavy artillery to be the best way to deal with them, though he had to fend off waves of them as they attacked the Ark. Vortex likewise encountered Autobot Marauders while trying to destroy a bridge, a few Autobot Marauders were seen on board of the Ark, trying to stop the attack of Bruticus.
