“”A present ungraciously given is ungraciously received; an order badly given is badly executed.” [“L’Ame du Soldat”] “The crisp, calculated, and forceful way of giving an order should produce a forceful way of executing it.” [“L’Ame du Soldat”]
In giving an order we should first consider the object; secondly, calculate the means; for it is worse than useless to give an order, either in the field or on training, which cannot be carried out, for such an order simply creates confusion. Thirdly, once an order has been given, leave the method of its execution to the recipient, for, if he is not man enough to carry it out, he should never have been placed in a position to receive orders at all.”
