Sound Military Decision. Naval War College
should in turn permit strategy to accomplish its further objective.
Consequently, every military situation has both strategical and tactical aspects. The nature of the objectives to be attained at a particular time, and the action to be taken to that end, may be governed chiefly by strategical, or chiefly by tactical, considerations. Whether an operation is distinctively strategical or tactical will depend, from the standpoint of the commander concerned, on the end which he has in view.
To attain its objective, strategy uses force (or threatens such use) (see page 8) as applied by tactics; tactics employed for a purpose other than that of contributing to the aims of strategy is unsound. Proper tactics, therefore, has a strategic background. Definition of tactics as the art of handling troops or ships in battle, or in the immediate presence of the enemy, is not all-inclusive. Such a view infers that the field of battle is the only province of tactics, or that strategy abdicates when tactics comes to the fore.
Actually, while tactical considerations may predominate during battle, their influence is not confined to the immediate presence of the enemy. Tactical dispositions are frequently adopted for convenience, for time saving, or for other reasons, long before entry into the immediate presence of the enemy. Nor do strategical considerations end when battle is joined. Tactics, unguided by strategy, might blindly make sacrifices merely to remain victor on a field of struggle. But strategy looks beyond, in order to make the gains of tactics accord with the strategic aim. Strategy and tactics are inseparable.
It is thus the duty of tactics to ensure that its results are appropriate to the strategic aim, and the duty of strategy to place at the disposal of tactics the power appropriate to the results demanded. The latter consideration imposes upon strategy the requirement that the prescribed aim be possible of attainment with the power that can be made available.
Consequently, while the attainment of the aims of strategy, generally depends upon the results gained by tactics, strategy is initially responsible for the success of tactics. It is therefore in the province of strategy to ensure that the attainment of tactical objectives furthers, exclusively, the aims of strategy, and also that the tactical struggle be initiated under conditions favorable for the attainment of the designated objectives.
Command of the Armed Forces. The initial requisite to the effective use of the armed forces is an agency authorized to direct them.
Command directs the armed forces. It is vitalized and personified in the commander, the human directing head, both of the whole and of organized groupings in descending scale of importance. Its responsibility, during peace, is the perfection of the armed forces to the point of readiness for war and, during the conflict, their effective employment.
Training for command, to be effective, is necessarily dependent upon an understanding of the position occupied by the commander, and of the role which he plays. Accordingly, this understanding is an essential in the study of that aspect of command training which has as its purpose the development of ability to reach sound decision.
The ideal of military command combines the best of human qualities with sound knowledge of the capabilities and limitations of the armed forces. It recognizes in war a form of human activity whose conduct, like that of all other human activities, is subject to natural law. It applies to the mastery of the problems of war, therefore, the natural mental processes of human thought (see Chapter II); it adapts these natural processes to a specific purpose, and consciously develops their use to the maximum degree for the attainment of this end. As command ascends the scale, its viewpoint broadens. Experience and added knowledge, with increasing authority and responsibility, lead to a concept of war more and more comprehensive, with the resultant growth in ability to evolve and put into effect a general plan for the effective control of collective effort.
Unity of Effort. An objective is best attained by effective application of properly directed effort, exerted by a single individual or by groups of individuals. Where individuals are collectively concerned, unity of effort is the most important single factor contributory to the common success. The basic condition to be sought by the armed forces is an harmonious whole, capable of putting forth combined effort, intensified in strength because of the collective feature, and rendered effective by its unity.
The Chain of Command. Within the limits of human capacity, an organization can exert its combined effort with greater effect the more closely the exercise of command represents the act of a single competent commander. To divide the supreme command in any locality, or to vest it in a body rather than in an individual, is necessarily to diffuse responsibility. In that degree there is then incurred the danger, through confusion of wills and ideas, of delaying decision and of creating corresponding diffusion of effort.
Realization of this danger has led the military profession to entrust command, subject to justifiable exceptions (see page 71), to a single head, while ensuring, by careful selection and training of personnel, that competent individuals are available for this duty. Although this method is in seeming conflict with the restriction imposed by recognized limitations of human capacity, the difficulty is effectively met through the chain of command, whereby responsibility is assigned and authority is transmitted without lessening of ultimate responsibility. Responsibility and authority, the latter properly apportioned to the former, are inseparably inherent in command, and may not justifiably be severed from one another.
In the abstract, the chain of command consists of a series of links, through which responsibility and authority are transmitted. The supreme commander is thus linked with his successively subordinate commanders, and all are disposed on, so to speak, a vertical series of levels, each constituting an echelon of command.
By means of the chain of command, a commander is enabled to require of his immediate subordinates an expenditure of effort which, in the aggregate, will ensure the attainment of his own objective (page 3). He thus assigns tasks to his immediate subordinates, whom he holds directly responsible for their execution without, however, divesting himself of any part of his initial responsibility. The accomplishment of each of these assigned tasks will involve the attainment of an objective, necessarily less in scope than that of the immediate superior but a contribution to the attainment of the latter.
The character and magnitude of the objective of the highest echelon involved will have considerable bearing upon the number of echelons required for its attainment. Whatever the number, a commander on a particular echelon occupies the position of an immediate subordinate to a commander on the next higher echelon, and that of an immediate superior with relation to a commander on the next lower echelon. Within these confines, authority is exercised and accomplishment exacted, both to the extent calculated to ensure unity of effort.
There may frequently be found two or more commanders occupying coordinate positions on the same echelon, all with the same immediate superior, and all charged with loyalty to him and to each other in the attainment of a common objective. In no case, however, will a commander be directly answerable to more than one immediate superior for the performance of the same duty. Thus is fulfilled the requirement that the command, although relatively narrower in scope as the scale is descended, be reposed in a single head.
The experience gained and the knowledge acquired during early service on the lower echelons provide a basis for later expansion of viewpoint, a better understanding of the position occupied by the subordinate and of the obligations of higher command, including its dependence on subordinates. As the echelons of command are ascended, the details involved become more and more numerous, because of the increased scope of the problems. On the higher echelons, therefore, staff assistance is provided so that the commander may be left free to consider matters in their major aspects. The staff of a commander is not, however, a part of the chain of command; its members, as such, exercise no independent authority.
A chain of command is not created by the subdivision of the officer corps into grades on a basis of relative rank. Such subdivision is for the purpose of classification from the standpoint of potential competency and capacity for responsibility, and carries no authority to command by virtue of rank alone. Organization, systematized connection for a specific purpose,
