Krourk Ogryn Auxilia
In close quarters fighting they are brutal even for Ogryns and considered little better than Orks. Because of their feral, indiscriminate savagery, they are only rarely used in large formations and always with devastating consequences. Though little can stand against the destructive fury of several thousand berserk Ogryns, their inability to distinguish between friend and foe results in collateral damage often outweighing the advantages of large formations. Many officers in the Imperial Guard consider the Ogryns of Krourk to be a primitive weapon of mass destruction when deployed en-masse.
Recruitment & Training
Krourk is a high-gravity steppe world of little use to the Imperium other than its population of Ogryns. The Ogryns of this world live harsh lives and the Imperium has left them to develop on their own. As such the Ogryn of Krourk have developed a highly competitive and violent tribal society. In times of crisis, Departmento Munitorum recruiting forces will descend to the surface and capture a few tribes to be taken to the stars for use in the Imperial Guard.
The Krourk are used for their brutally effective close combat ability. They are considered too stupid and uncontrollable to be taught even the simple workings of the Ogryn Ripper Gun. Instead, they are armed with heavy close combat weapons and sent en-masse at the enemy. Once in battle the Ogryns of Krourk are completely uncontrollable until they have destroyed everything in sight. As such they are rarely used as a complete force, instead being attached a squad at a time to other units.
