Principia Belicosa
The 'Principia Belicosa' or 'Principia Bellicosa' was an ancient military text dated from the Roman Era on the planet Terra, from which the Emperor drew inspiration to create the template for the organisation for the Space Marines Legions, during the Great Crusade.[3] It succeeded the Hexagrammaton formations of the early Astartes during the Unification Wars[1], and was succeeded after the Horus Heresy by the Codex Astartes.[2]
Excerpts
Martial vigour and ferocity are virtues, to be sure. But do not throw your force blindly into battle and say that this is vigour. It is not. Before committing your forces, examine the situation. Review your own strength, and that of your enemy. Remember your own objectives, and try to anticipate those of your opponent. He who fights without understanding the battle places himself at the disadvantage.[4b]
Superiority of force is key and the key to superiority is above all, structure. With structure comes order, with order the ability to carry out purpose, and only through clear purpose can victory be perceived[4a]
