The true strength of the Emperor’s largest military force lies not in their artillery, trenches, and tanks, but in the courage of the ordinary men and women of the Astra Militarum. Against the countless foes of the Imperium, Guardsmen stand together. They fight to live and die not only for the glory of the God-Emperor, but for their fellow soldier. To survive against the Ruinous Powers and the overwhelming xenos tide, the trust and bravery of daring Catachan jungle fighters, indomitable Cadians, stoic Kriegsmen, and more will be tested to the limits.
