Reinforced Ram

From Lexicanum

A Reinforced Ram is similar to a Big Grabber, Wrecker Ball and Boarding Plank in that it is a device used in close combat, with enemy vehicles, by Ork vehicles. It is part of the vehicle upgrades list for the Orks and is effectively a large pointed object used to ram and disable enemy vehicles, especially destroying tracks. It is however, quite cumbersome and as such is useless against anything which can move out of the way fast enough.
