The decision is taken in private, and when the two men come out, there is only one decision. They have amalgamated it; they share one mind with each other. Should the opinions have differed, in the evening of this happy day in a military marriage the two halves will no longer know who gave in. The outside world and military history will not have knowledge of a domestic quarrel. The competence of command and control is based on this fusion of the two personalities. It does not matter if the order bears the commander's signature, or if the Chief of Staff has signed it for the High Command (today 'For the commander') according to our old custom. The commander always issues his orders through his Chief of Staff, and even the most senior subordinate leader must submit himself to his orders without objection, because his orders will always be given on behalf of the supreme commander.
