That this procedure may be successfully and repeatedly applied in the fast-moving events of the decisive tactical engagement is, more particularly, the goal of mental preparation for the exercise of command. PART II THE EXERCISE OF PROFESSIONAL JUDGMENT IN PLANNING CHAPTER VI THE SELECTION OF A CORRECT OBJECTIVE (Including the Determination, in Proper Detail, of the Action Required for its Attainment) The First Step--The Solution of a Basic Problem (The Estimate of the Situation) The type of problem distinctive of the first step, now to be discussed, is a basic problem. It is the most likely type when an organized chain of command is in effective operation, the incentive for solution being derived from a directive issued by higher authority (Chapter V). The problem of the first step is described by the question, "What objective should I select, and what action (in outline) should I take for its attainment, in order to achieve the objective assigned to me by higher authority?" The procedure for solution of the type of problem distinctive of the first step is that already indicated as applicable to all military problems, i.e., a specialized employment of the natural mental processes (Chapter II) through the application of the Fundamental Military Principle. The studied application of the Principle is assisted through the Estimate Form which provides a more detailed guide. The fundamentals of the Estimate Form have already been discussed (Chapter V). Except for emphasis, or to afford a basis for further detailed discussion, the basic matters previously dealt with are not repeated in the present chapter. It is therefore advisable, before studying the details applicable to the first step, to make an adequate review of the pertinent portions of the preceding chapter. With the necessary background thus provided, the Estimate Form can be followed with a minimum of distraction caused by reference to related subjects. For special emphasis, it is repeated here (see also page 110) that the Estimate Form is a flexible guide. The commander is of course at liberty to vary the procedure according to his particular needs and the nature of his problem; however, he will bear in mind that errors of commission or of omission arising by reason of departure from the essential features of the procedure may disrupt orderly reasoning. The Estimate Form is divided into sections and sub-sections, each of which presents a subject for consideration. The Form follows, sequentially, the salient features of the natural mental process described in Chapter II. It will be seen, from an examination of the section headings listed below, that Section I has to do with establishing the basis for solution of the problem; Sections II, III, and IV relate to the actual process of solution through consideration of various courses of action; while Section V states the conclusion reached.
