With the growing severity of ork weapons, the Fourth Ork Assault was marked by the discovery of true ork war machines. The local forces immediately went about deploying armoured regiments of tanks and their own war machines to launch a full counter-attack. For the first time since the wars start, the people of Olicana were able to bring about retribution as one of the orks greatest strongholds, Hevy Casol, was destroyed by the combined might of the Olicanan Guard and the Torlan Hammers.
