Do not fail your Brothers. Though their bodies die, their spirit must return to the Chapter. That is your charge.

Adeptus Astartes
"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 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
