The Deff Rolla is a more powerful version of the Reinforced Ram - a great metal cylinder lined with spikes and barbs that brings the weight of the vehicle to bear on anything on its way. It is tremendously effective, allowing the vehicle to crush infantry and even other vehicles under it. It is often attached to the front of larger Ork vehicles, such as Battlewagons and Battlefortresses.
