Brother Coa's video: Cadians - Imperial Guard finest

The Cadian Shock Troopers are Imperial Guard regiments from the fortress world of Cadia. Cadia is located at the edge of the Eye of Terror and so forms the first line of defence against Chaos incursions, such as the Black Crusades. Because of this, Cadia is regarded as one of the most strategically important planets in the Galaxy. Cadian regiments have been involved in many wars, campaigns and battles off-world. Because of this, the Cadians are widely regarded as the best troops in the Imperium, short of the Space Marines themselves.9,20 With the coming of Abaddon's 13th Black Crusade, they were forced to fight on their own soil. In the early stages of the Black Crusade, they confronted and destroyed the Volscani Cataphracts (a renegade Imperial Guard army) at the Battle of Tyrok Fields on Cadia itself. They were eventually successful at securing the Cadia system, although at a heavy price to human life and resources. Cadians were also among the forces that fought in the Third War for Armageddon. Due to its location, Cadia and its surrounding neighbours are some of the most militarised and fortified worlds in the Imperium. On Cadia (during the 13th Black Crusade), they are led by the formidable Lord Castellan Ursarkar E. Creed. Background song: Europa by Globus
