Correct appreciation of this objective, in its relationship to the further effect to be produced, is thus the principal consideration in reaching an understanding of the appropriate effect desired. It is, to repeat, through an understanding of this factor and of the factors of relative fighting strength that the commander establishes the basis for the solution of his problem. (See Section I of Chapter VI, page 118). The Solution of a Military Problem. When the commander has thus obtained an understanding of the basis of his problem, the actual procedure of solution is undertaken through the consideration of the factors involved in their influence on the various plans for the attainment of the appropriate effect desired, as thus established. The best plan, selected and embodied in outline in the decision, can then be further developed, if necessary, into a general plan for the commander's force and, finally, into a detailed plan, as the solution of the problem. (See page 22.) The Major Components of a Military Problem. Each plan considered by the commander will involve (page 21) two major considerations: namely--an effect to be produced and the action required to produce it; or, in military terms, a correct military objective (or objectives) and effective operations for its attainment. The selection of correct military objectives and the determination of effective operations for their attainment are therefore the two major components of a military problem, because they are the principal considerations on which depends the soundness of military decision. To meet these requirements is a prime function of command, one which demands professional judgment of the highest order. The major components of a military problem are of course intimately connected, because a purposeful action, accomplished, is equivalent to an objective, attained. Furthermore, the attainment of an objective involves the accomplishment of effective operations. Because of the importance of the subject, the relationship between these two major components deserves very careful analysis. As has been observed (page 30), the action to be taken depends, in the first instance, on the effect to be produced. Therefore, the objective is, as compared to the action to attain it, the paramount matter. Moreover, there is necessarily included, in the procedure of selecting a correct objective, a consideration as to whether the action to that end will be feasible and as to whether the consequences involved will be acceptable on the basis of the costs which will be exacted. If, then, the objective has been correctly selected in any situation, this procedure will have included, as a necessary incidental, the determination also, in the proper detail, of the operations required for its attainment.
