(1) Summary of the Enemy's Situation. Frequently it may happen that the enemy does not have certain significant information. The fact of such lack of information may have been established by the conclusions drawn as to relative fighting strength (Section I-B). If this be the case, notation of the fact is made at this point in the commander's estimate of the enemy's situation. If doubt exists as to the extent and accuracy of the enemy's information, it will be desirable to credit the enemy with any knowledge which it would be dangerous for the commander to conclude was not available to his opponent. In summarizing the enemy's situation, the commander may brief the procedure by indicating those significant features of his own situation, as summarized in Section I-A and as particularized in Section I-B, which he does not consider are known to the enemy. The commander will also indicate here any items of important information as to which he has only a suggestion or an inkling, but which he considers may be known in greater detail to the enemy. (2) Analysis of the Effect Desired by the Enemy. It may appear on first thought that the best basis for determining the pertinent enemy courses of action is to make a deduction of the enemy's mission. Sometimes, undoubtedly, this is the case. However, it is not always possible to deduce the enemy's mission correctly. If the deduction is incorrect the remainder of the estimate will be on an unsound basis. If, as may happen, the enemy's plan has been captured, or if, by some other method, conclusive information has been obtained, it may be possible to state the enemy's mission. Even then, however, the enemy's mission may sometimes be changed. It is thus evident that the commander, by restricting his thought, may frequently fail to consider all of the enemy capabilities which may materially influence his own course of action. With this precaution in mind, the commander, at this point in his Estimate, proceeds to analyze the effect desired by the enemy. The commander intends to use his deductions, if such use appears to be sound, to narrow the field of consideration as to enemy courses of action. However, he reminds himself that such restriction will be dangerous unless it is established on sound grounds. The first mental act toward determining the effect desired by the enemy is to form a reasoned opinion as to the situation which the enemy wishes to maintain or to create. The maintenance or creation of this situation, existent or to be brought about, is an enemy objective.
