In any action in which the several services are joined, any American officer may expect the same measure of respect from the ranks of any other service as from his own, provided he conducts himself with a dignity and manner becoming an American officer. For all officers, due reflection on these points, relating to the character of our men in war, is not more important than a continuing study of how they may be applied to all aspects of training, toward the end that we may further strengthen our own system. This is the grand object in all military studies. That service is most perfect which best holds itself, at all times and at all levels, in a state of readiness to move against and destroy any declared enemy of the United States.
