Both requirements have to do with the factors of relative fighting strength. Fighting strength is derived from the means available as influenced by the characteristics of the theater. Relative fighting strength is determined by a weighing of these factors against the means opposed, as influenced also by the characteristics of the theater. These are the factors, then, which are next studied in the Estimate. They are studied in order to complete the establishment of the basis for the solution of the problem. * * * * * The factor of consequences, as listed in the Fundamental Military Principle, is related to the factors pertinent to feasibility. This is true because consequences are assessed, in the Estimate, on the basis of the envisaged results of proposed actions. These results are necessarily predicated on the grounds established by consideration of the factors of relative fighting strength. The study of relative fighting strength thus provides not only a sound basis for the determination, later, of the feasibility of courses of action, but also of their acceptability with respect to consequences as to costs. Particular emphasis is placed on the conclusion as to relative fighting strength, to the end that specific advantages may be ascertained. Such a study is primarily concerned with information:--its collection, its analysis, its evaluation, and its interpretation so as to convert it into military (naval) intelligence (page 76), with a view to its use by the commander in the solution of his problem. Information as to forces present and as to their positions is of course prerequisite to a clear comprehension of the possibilities as to physical objectives, as to relative positions, as to apportionment of fighting strength, and as to freedom of action. The commander may choose whether he shall, in his estimate, first consider the means available and opposed, or reverse the order and give priority to the characteristics of the theater. In a particular situation, the significance of these characteristics is frequently determined by the capabilities and limitations of the means available and opposed. For this reason, these means are first discussed in this treatment, which thereafter includes the analysis of the characteristics of the theater. The capabilities and limitations of the means, and the significance of the characteristics of the theater, may be expressed in terms of certain specific factors (page 25). Each of these factors may influence, or be influenced by, any or all of the others. Situations occur in which certain factors exert little or no influence. Yet, in other situations, these same factors have a paramount effect. The classification of factors utilized in the following treatment is applicable to most military problems.
