Deficiencies in technical training are capable of imposing grave restrictions upon freedom of action. Material equipment, even though it may represent the acme of perfection in design and construction, will not surely function unless skillfully operated and maintained. Even though mobility and endurance be otherwise assured, the capacity which they represent is not susceptible of effective employment unless the methods of movement, i.e., of effecting change in relative position (page 59), are intelligently planned and are developed to a point which assures facility of operation when in the hands of skilled personnel. Tactical training, not omitting that required for joint operations (page 67), is one of the vital factors of fighting strength, with respect, more especially, to its contributions to freedom of action. A state of high and stable morale (page 9), founded upon sound discipline, is an invaluable characteristic of fighting strength. An understanding of the human being is therefore an important feature of the science of war. Discipline, in its basic meaning, is the treatment suitable to a disciple. The objective of discipline is therefore the creation and maintenance of the spirit of willingness to follow where the commander leads. The exercise of leadership is not restricted, however, to those occasions when the commander can be physically present. The exigencies of war and the requirements of control prevent the commander from being always, personally, in the forefront of action. These restrictions as to considerations of space however, impose no limitations on leadership in terms of time. The influence of the competent commander is a factor always acting to shape the situation according to his will (page 47), though the necessities of the moment may compel his presence elsewhere. The ability to create and maintain a faithful following who will execute the commander's will wherever he may be (page 15) is, accordingly, a primary attribute of command. With this objective in mind, the true disciplinarian runs no risk of confusing harshness with the exercise of justice. He understands the difference between an overbearing arrogance, arising from unconscious ignorance, and the pride which springs from a justified self-respect. He appreciates the distinction between mere stubbornness, which would alienate his followers, and the necessary firmness which binds the bonds between the leader and the led. He realizes that comradeship, without presumptuous familiarity, is the firmest foundation for mutual loyalty (page 14). He knows that kindness and consideration, without suggestion of pampering, will not be mistaken for weakness by any subordinate worthy of the name.
