The nature of such corollaries may best be shown by an example. It is supposed, for instance, that the commander has made the Decision "to guard the Eastern Caribbean barrier against enemy penetration". During the course of his estimate of the situation, he has come to the conclusion that his operations to carry out this Decision will extend into the area limited by Port X on the north, and Port Y on the south. This conclusion is a deduction, which immediately assumes importance when the Decision is made. The commander states this deduced conclusion here, in connection with the Decision, for future guidance in resolving the Decision into detailed operations, as well as for later use in his directives to limit the action of his subordinates. No particular form is specified for such corollaries. It is satisfactory to list them as Corollary I, Corollary II, etc. They do not constitute a part of the Decision. Relation of the Decision to the Detailed Plan and Directives. The Decision is the basis for the commander's plan of action for his entire force. This plan is promulgated in one or more directives. The Decision, as it appears in the Estimate, is not yet the concern of subordinate commanders. It does not become their concern until it is used in directives. As incorporated in the commander's detailed plan and in his directives, the Decision, whether further developed or not, constitutes the commander's general plan and is referred to in those terms. The Decision, as it appears in the Estimate, is not bound by any rigid specifications as to form. Later (Chapter VII), when the commander prepares for the inauguration of planned action by the formulation and issue of directives, he assumes the obligation of conveying the substance of his Decision to his subordinates in clear language. At that time he will again have to subject its expression to scrutiny, and may find that he has to make modifications solely for clarification. CHAPTER VII THE RESOLUTION OF THE REQUIRED ACTION INTO DETAILED OPERATIONS (The Second Step--The Solution of Subsidiary Problems) The problem of the second step may be stated in question form as follows: "What action should I take for the attainment of my objective as selected in the first step?" [Sidenote: For convenience a tabular form, inserted in the appendix, page 224, gives page references to the principal subdivisions of this Chapter.] Having arrived at his basic Decision, the commander, if he wishes to put it into effect, will proceed to formulate a plan of action which can be cast into the forms of directives for execution. In making such a plan, he provides for operations in the detail proper for his situation. He thereby expands the general plan, indicated in or developed from his basic Decision, into a complete plan which can readily be placed in the Order Form (Chapter VIII) as a directive or directives for the guidance of his subordinates.
