pace Marines are humanity's finest warriors. Genetically tailored for their role and utterly loyal to the Emperor, the Space Marine Chapters represent mankind's greatest hope of victory in the unending wars for survival. A Space Marine is stronger and tougher than an ordinary human, with faster reflexes and superior co-ordination.

All Space Marines belong to a warrior cult. Space Marines are therefore spiritual brothers as well as brothers in arms. This dual role as physical and spiritual warriors is very important, and it is what makes the Space Marines so dedicated.
