Nothing so warms the heart of a superior as that, on giving an order, he sees his subordinate salute, say "Yes sir," then about face and proceed to carry it out to the hilt, without faltering or looking back. This is the kind of man that a commander will choose to have with him every time, and that he will recommend first for advancement. On the other hand, clarification of the object is not only a right but a duty, and it cuts both ways. Orders are not always clear, and no superior is on firm ground when he is impatient of questions which are to the point, or resentful of the man who asks them. But it is natural that he will be doubtful of the man whose words show either that he hasn't heard or is concerned mainly with irrelevencies. The cultivation of the habit of careful, concentrated listening, and of collected thought in reading into any problem, is a principal portal to successful officership. To say that promptness and positiveness in the execution of a mission are at all times major virtues does not imply that the good man, like an old fire horse, moves out instantly at the clang of a bell. Soundness of action involves a sense of timing. Thoroughness is the way of duty, rather than a speed which goes off half-cocked. There is frequently a time for waiting; there is always time for acute reflection. The brain which works "like a steel trap" exists only in fiction. Even such men as General Eisenhower, or Admiral Nimitz, or for that matter, Gen. U. S. Grant, have at times deferred decision temporarily while waiting for a change in tide or circumstance to help them make up their minds. This is normal in the rational individual; it is not a sign of weakness. Rather than to cultivate a belief in one's own infallibility, the mature outlook for the military man is best expressed in the injunction of the Apostle Paul: "_Let all things be done decently and in order._" Grant, wrote of the early stage of his advance on Richmond: "At this time I was not entirely decided as to how I should move my Army." From the pen of General Eisenhower come these words: "The commander's success will be measured more by his ability to lead than by his adherence to fixed notions." Thus, in the conduct of operations not less than in the execution of orders, it is necessary that the mind remain plastic and impressionable. Within military organization, to refuse an order is unthinkable, though to muster a case showing why some other order would serve in its place is not undutiful in an individual subordinate, any more than in a staff. By the same rule, insistence that an order be carried out undeviatingly, simply because it has been given, does not of itself win respect for the authority uttering it. Its modification, however, should never be in consequence of untempered pressure from below. To change or rescind is justified only when reestimate of all of the available facts indicates that some other order will serve the general purpose more efficiently.
