Space Marines

The Space Marines are one of the major forces available in the table-top wargame Warhammer 40,000. They are also known as the Adeptus Astartes and by the sobriquet "Angels of Death". They are the supersoldiers of the Imperium of Man. The Space Marines can be seen as the scalpel of the Imperium, as compared to the sledgehammer of the Imperial Guard.
They are elite soldiers, specially chosen for natural ability, and have their innate superiority enhanced further by a combination of extensive training, mental conditioning and genetic alteration. Their dedication and steadfastness is a product of this superiority and indoctrination. Their structure and cultures are monastic in nature although often display features of other strict martial orders and warriors cultures throughout history.
As befits such an elite force they are given equipment to match their abilities. They wear power armour to give them all-over protection and the ability to survive in hostile environments, and are equipped with superior weaponry as well, in the form of Bolters. Space Maries are also much taller than a standard human being, somewhere between eight and ten feet high when clad in ther power armour.
