Since the particular character of each salient feature of a situation, or of an operation, is determined by the influence, exerted by the identical factors (as noted), there is a resulting interdependency, important though indirect, among the several features. This interdependency is explained hereafter. (Chapter IV). The Fundamental Military Principle. The Fundamental Principle for the Attainment of an End in human affairs (page 32) has invited attention to the factors, pertinent to suitability, feasibility, and acceptability, seen to be applicable, as well, to any military effort (page 35). As also noted, a military effort will necessarily consist of military operations, whose salient features depend upon the same factors. The factors, in turn, have been observed (page 32 and following) to be interdependent. [Illustration: THE FUNDAMENTAL MILITARY PRINCIPLE (diagram)] These considerations lead to the formulation of a derivative of the Fundamental Principle for the Attainment of an End in human affairs, in the form of The Fundamental Military Principle The attainment of a military objective (the creation or maintenance of a favorable military situation) depends on effective operations involving the salient features of Effective action with relation to correct physical objectives, Projection of action from advantageous relative positions, Proper apportionment of fighting strength, and Ensurance of adequate freedom of action, each fulfilling the requirements of Suitability, as determined by the factor of the appropriate effect desired, Feasibility, by reason of relative fighting strength as determined by the factors of the means available and opposed, influenced by the factor of the characteristics of the theater of operations, and Acceptability, as determined by the factor of the consequences as to costs, which factors are in turn dependent on each other.
