The Imperium of Man is the greatest power in a galaxy wracked by endless war, locked in daily battle for survival against the most horrific and implacable enemies imaginable. Its destruction is held at bay by the might and courage of its inexhaustible armies, the brave soldiers that make up the ranks of the Imperial Guard. This mighty force is Mankind's primary and most numerous defence, numbering billions upon billions of soldiers raised as tens of thousands of regiments from all the myriad types of world found in the Imperium. Regiments vary enormously across the galaxy and include all manner of warriors, from disciplined ranks of infantry, glorious cavalry, whole regiments of tanks and artillery to the leviathan-like super-heavy tanks and titanic Capitol Imperialis. They are the Imperial Guard - the Hammer of the Emperor.
