A Dreadnought is a cybernetic combat walker of intermediate size used by the Chapters of the Adeptus Astartes as heavy infantry support for their Space Marine companies. The most common form of Dreadnought deployed in the late 41st Millennium is officially designated a Castraferrum Pattern Dreadnought. Even the superhuman Space Marines are still mortal and can fall in battle despite legends to the contrary amongst the common people of the Imperium of Man. Dreadnoughts are war incarnate, towering machines that advance forwards with thunderous strides, fiery death roaring from the myriad of heavy weapons mounted on their hulls. They are terrifying foes, fighting with all the skill and ferocity of a Space Marine, but combined with the durability and firepower of a battle tank.
