The Astra Militarum is the implacable military arm of the Imperium, and one of the largest forces in the galaxy. On thousands of battlefields scattered throughout the galaxy, the soldiers of the Astra Militarum march to war. They are the Hammer of the Emperor, who with faith, fury and sheer weight of numbers crush heretics and xenos alike beneath their boots. Massed ranks of Guardsmen unleash concentrated salvoes of las-blasts while officers bellow orders over the thunderous roar of tank and artillery fire.
