Space Marines are organised into Chapters, each consisting of one thousand battle-brothers and possessed of their own armouries, fighting vehicles, space fleets and towering fortress monasteries. Though there is less than one warrior of the Adeptus Astartes for every planet in the Imperium, it is a testament to their sheer might and heroism that this number is still sufficient to hurl back the enemies of Humanity upon every front.
Space Marines are genetically engineered super-human warriors. Armed and armoured with the best equipment the Imperium can provide, they are the Emperor’s most elite fighting forces. To the Space Marines fall the most desperate and vital of the Imperium’s battles, holding the line where all others have fallen, or striking like the Emperor’s own blade to bring death to xenos warlords and daemonic abominations alike.
