"They shall be my finest warriors, these men who give of themselves
to me.
Like clay I shall mould them and in the furnace of war
I shall forge them.
They shall be of iron will and steely sinew.
In great armour I shall clad them and with the mightiest weapons shall they be armed.
They will be untouched by plague or disease; no sickness shall blight them.
They shall have such tactics, strategies and machines that no foe will best them in battle.
They are my bulwark against the Terror.
They are the Defenders of Humanity.
They are my Space Marines
...and they shall know no fear.
— The Emperor of Mankind

The Space Marines or Adeptus Astartes are foremost amongst the defenders of humanity, the greatest of the Emperor of Mankind's warriors. They are barely human at all, but superhuman; having been made superior in all respects to a normal man by a harsh regime of genetic modification, psycho-conditioning and rigorous training. Space Marines are untouched by plague or any natural disease and can suffer wounds that would kill a lesser being several times over, and live to fight again. Clad in ancient Power Armour and wielding the most potent weapons known to Man, the Space Marines are terrifying foes and their devotion to the Emperor and the Imperium of Man is unyielding. They are the God-Emperor's Angels of Death, and they know no fear.
