This procedure may also have a certain psychological advantage, in that the commander may thereby avoid becoming unduly impressed by the potentialities of enemy action. Occasionally, prior consideration of enemy courses may tend to put the commander, unnecessarily, on the mental defensive. First consideration of his own courses of action is especially appropriate for a commander whose mission requires him to assume the initiative, particularly when the relative fighting strength indicates that he can compel enemy action to conform to his. This is frequently the case when enemy action will chiefly affect details rather than the general trend of the operations. These reflections indicate that first consideration of his own courses of action will very frequently be advantageous to the commander. Such a sequence is therefore indicated preferentially in the Estimate Form, and next discussed. However occasions may arise when consideration in the reverse order is preferable. Sometimes the prior consideration of enemy potentialities has the advantage of making the commander's estimate more complete with respect to the obstacles which he is to overcome. Furthermore, when the effectiveness of his future action is seen to depend chiefly upon what the enemy can do, or when the initiative lies manifestly with the enemy, and when the commander's mission requires him to frustrate enemy action, rather than to assume the initiative himself, the prior consideration of enemy courses of action may be indicated. The commander may therefore consider the subject matter of Sections II and III in the order hereinafter followed, or he may reverse that order. SECTION II DETERMINATION OF SUITABLE, FEASIBLE, AND ACCEPTABLE COURSES OF ACTION A. Analysis of the Assigned Objective. In order further to clarify the problem, consideration of the commander's courses of action may profitably commence with an analysis (page 53) of the assigned objective. Section I-A contained an appreciation of this objective on the basis of the salient features of the situation. A close examination is now possible in the light of the additional information furnished by the full details (Section I-B) as to the means available and opposed, and as to the characteristics of the theater (page 121). Accordingly, the mission (page 121), is now again stated, and is restudied. The task is thoughtfully examined anew, in view of the forces and positions now known. The purpose is scrutinized with equal care, because it indicates the further end in view for the common effort. Now, obstacles to success which, in Section I-A, could not fully be appreciated can be examined against the background afforded by visualization of the enemy's ability to oppose the attainment of the assigned objective.
