Warhammer 40000
All of the worlds of the Imperium shall look to their own defense. They shall also look to the defense of the Imperium, and the prosecution of such wars as the Emperor in His wisdom shall decree. Therefore, each populated planet shall raise and maintain its own planetary defense force, and from the ranks of this defense force it shall provide the best of its troops for recruitment into the Imperial Guard, according to such requirements as shall be imposed by the Administratum.
