The foregoing considerations as to advantageous relative positions are applicable, not only in the realm of the commander's decisions as to his own action, but also to his judgments rendered when higher authority calls for recommendations (see page 42). Apportionment of Fighting Strength Fundamental Considerations. The assignment of a task may be expected to carry with it availability of fighting strength deemed adequate by higher authority for accomplishment of the operation involved. In appropriate instances, the higher command may call for recommendations as to the amount and character of the means deemed adequate by the subordinate for performance of the task with which he is, or is to be, charged (page 42). In any case, means having been made available, it remains for a commander to whom an objective has been assigned to apportion these available resources in such manner as to provide the requisite strength at points likely to be decisive, without unduly weakening other points. In effect, he is charged with a practical adjustment of means to ends. This responsibility is discharged by the effective utilization of means and prevention of waste nicely balanced through full consideration of all essential elements of a favorable military operation. The procedure involved has been indicated (see the corollary Principle for the determination of the Proper Means to be Made Available--page 34). The relation between the strength to be brought to bear in dealing with a selected physical objective, the tactical concern of the moment, and that necessary to the attainment of the strategical aim (see pages 9 and 10), constitutes a fundamental consideration in effecting such a balance. In making a correct apportionment, there will be involved not only the physical elements of fighting strength, but the mental and moral as well. With respect to mental and moral factors, the capabilities of particular commanders and organizations may be an important factor in apportioning forces to tasks. In the physical field, numbers and types occupy a prominent position, each however, requiring consideration from the standpoint of the existing situation. Thus, forces composed of appropriate types and suitably equipped and trained may exercise greater effect than numerically larger forces not so well adjusted to the requirements of the situation. On the other hand, numerical considerations become predominant under conditions otherwise substantially equal. These considerations, viewed in the light of the relationship of naval operations to land areas (page 63), indicate the importance which may attach to immediate availability, with a naval force, in addition to its own air strength, of a proper complement of land forces (with appropriate air strength) which are organized, equipped, and trained for amphibious operations.
