Forged through forgotten science and strengthened by duty and training, they are the Angels of Death - the Space Marines - and they were made for battle. By their heroics does Humanity endure. They are few - there are but a thousand Chapters, numbering a thousand each - yet through bravery, consummate skill and unceasing dedication, they are sufficient. Space Marines launch thunderbolt strikes into the heart of the foe, battling constantly against overwhelming odds to ensure the continued survival of Mankind itself.
