Space Marines, also known as the Adeptus Astartes or the Angels of Death, are the elite fighting force of the Imperium. They are far fewer in number than Imperial Guard, but are superior to the regular soldier in every way. Selected at an early age, a Space Marine is bio-genetically engineered, surgically enhanced, hypnotised, indoctrinated and trained to be the toughest warrior in the galaxy. They are deployed on the most dangerous missions in the harshest envrionments. They are bred with unflinching loyalty to the Emperor, and exist to serve the Imperium until their last dying breath.
