Section I-B of the intelligence estimate will take account of the factors as to intelligence and as to related matters which are noted in the Estimate Form (Chapter VI) for a basic estimate.

Section II will consider the possible procedures for obtaining information, i.e., for its collection, including reports from collecting agencies.

Section III will consider the capabilities of the enemy as to counter-intelligence measures.

Section IV will compare the various procedures open for the collection of information and for reports thereof.

Section V will include a decision as to the essential elements of information desired. The decision will be in sufficient detail to serve as a general plan (or a basis therefor), to be developed into a detailed plan for obtaining information and for converting it into intelligence.

A detailed intelligence plan will include appropriate information and a.s.sumptions. It will state the general plan for obtaining intelligence. This statement will include the essential elements of information desired. The plan will include appropriate tasks for information-collecting agencies, with times and destinations for reports of information. The task for each collecting agency will be based on the general plan (above); such task will also be synchronized with the projected operations prescribed for such agency in current Operation Orders (Chapter VIII). The agency's inherent capabilities--its limitations as well as its powers--will be given due consideration. Requests to be made on collecting agencies not under the commander's control will be noted in the information (as to own forces) given in the plan (see above).

Logistics arrangements will include, for example, provisions for handling prisoners of war, the disposition of captured doc.u.ments and other materials, and the supply of maps, charts, and photographs.

Counter intelligence measures will be specified where applicable.

These include such matters as censorship, press relations, camouflage, and propaganda. Finally, the plan will include provision for the rendition of routine and special reports, for special charts (or maps) accompanying or pertinent to such reports, and for any intelligence conferences.

The essential elements of information desired are frequently stated in question form. Each question deals with an enemy course of action or with one or more of the enemy operations pertaining to such a course (page 161).

The tasks a.s.signed to collecting agencies, or the requests made on collecting agencies not under the commander's control, will call for information (negative, if desired, as well as positive) as to specific indications of the enemy's action--past, present, or intended--and of the characteristics of the theater as related thereto. The indications to be sought for and reported are carefully determined by the commander in expectation that information obtained as to such matters will enable him to draw conclusions which will answer the questions posed by the essential elements of information.

For example, essential elements of information, with corresponding indications, may be as follows:

Essential Elements Indications

1. Will the enemy patrol the a. Presence or absence of enemy trade route from A to B? forces (number and types of vessels) between meridians--and--, as far north as--and as far south as--.

b. Times enemy forces observed in area noted.

c. Apparent activity of enemy forces so noted.

2. Will the enemy cover focal a. Presence or absence of enemy points M and N? forces (numbers and types of vessels) in (a specified area or areas).

b. Times enemy forces observed in areas noted in a, above.

c. Apparent activity of enemy so noted.

d. Has M or N been prepared as a naval base; an air base for seaplanes, for land planes?

Is M or N readily accessible to enemy battleships? What are the characteristics of the available entrances to sheltered anchorages? (Etc.)

Another type of subsidiary problem which may call for a separate subsidiary plan relates to logistics (page 162). This problem is particularly applicable to the planning stage, because the contingencies which it involves can, to a considerable degree, be foreseen. In this case the situation which the commander usually desires to bring about is adequate freedom of action with respect to supply and related matters. He wishes to solve this problem so completely during the present step that a logistics plan, concurrently executed with his basic plan, will require minimum subsequent attention.

A logistics estimate by the procedure distinctive of the first step will include in Section I-A a summary of the pertinent features of the existing strategical and tactical situation, and of contemplated strategical and tactical operations. It will also include a statement of the salient features of the existing logistics situation. The incentive, to be found in a previous decision of the commander, will be noted. The a.s.signed objective will be the making of adequate provision for logistics support. The mission will be:--

(Task) to make provision for adequate logistics support,

(Purpose) in order to contribute to freedom of action in the operations contemplated. (In each particular case the operations contemplated will be indicated by proper phraseology in the mission or by reference to the summary of the situation).

Section I-B of the estimate will take account of the logistics factors cited in the Estimate Form (Chapter VI) for a basic estimate, but will specify details to the further extent necessary.

Section II will discuss the various possible procedures for affording appropriate logistics support of the various categories.

Section III will discuss enemy actions to hamper or prevent adequate logistics support.

Section IV will deal with selection of the best logistics procedure.

Section V will state the decision as to the essential elements of the logistics support to be afforded, in such detail as will const.i.tute a general plan (or a proper basis therefor) from which a detailed plan can be developed.

A detailed logistics plan, developed from the foregoing estimate, will a.s.semble the necessary information and a.s.sumptions. It will state the general plan for logistics support. It will then provide for appropriate action as to each type of logistics support, or will state proper tasks for the several subdivisions of the force concerned therewith. It will include, also, any coordinating measures. It will, finally, make provision for exercise of command with reference to logistics support, as well as for any necessary or desirable time elements and similar considerations.

From all of the foregoing discussions it is apparent that the numerous possible subsidiary problems are all related to the basic problem either directly or through an intervening subsidiary problem. The nature of this relationship is seen through the (subsidiary) purpose, determined for the particular (subsidiary) task; therefore, the understanding of the problem involves a statement or visualization of the (subsidiary) purpose in each case.

PART III

THE EXERCISE OF PROFESSIONAL JUDGMENT IN THE EXECUTION OF THE PLAN

CHAPTER VIII

THE INAUGURATION OF THE PLANNED ACTION

(The Third Step--The Formulation and Issue of Directives)

In the discussion which now follows, it is demonstrated that, if the second step (Chapter VII) has been carried through completely, the formulation of directives requires only the completion of details of the Order Form, which is explained.

The various types of naval plans and directives are also described.

Scope of the Third Step. As previously stated (in Chapter V, on page 107), the inauguration of the planned action (the third step) begins when the commander forms the intention of immediately promulgating, as one or more directives, his solution of the problem represented by the second step. The third step ends at the moment when the problem becomes one of supervising the planned action in the course of its execution.

Military Plans and Military Directives. A plan is a proposed scheme, procedure, or method of action for the attainment of an objective. It is one of the essential links between decision and action.

A directive, in the general sense, initiates or governs conduct or procedure. It is the means by which one's will or intent is made known to others. Sometimes the word is employed as a synonym for "order"; at others, it carries the significance of various instructions ranging from the simple to the complex; at still others, it denotes a plan formulated to be placed in effect in a particular contingency or when so directed. In all cases, a directive, to be suitable as a guide for others, has as its origin a plan.

The words plan and directive are used herein as follows:--A plan may exist only in the mind. Even if formulated and set down in writing, it may receive no distribution. A plan continues to be exclusively a plan so long as it concerns the originating commander alone, and it never loses its ident.i.ty as a proposed procedure or method of action. When, however, the commander forms the intent of promulgating the plan immediately, the plan becomes also a directive. At this point, as noted in the preceding paragraph ("Scope of the Third Step"), the execution phase begins, from the standpoint of the exercise of mental power, with the inauguration of the planned action.

A directive may therefore be (1) an order effective upon receipt, in which case it may be an order placing in effect a plan already issued; or a directive may be (2) a formulated plan which the commander intends to issue immediately to his subordinates.

Accordingly, certain written instruments prepared under the designation of plans are also included under the cla.s.sification of directives. In the use of these terms hereinafter, the distinction between a plan viewed as a basis for a directive, and a plan intended to be promulgated as a directive, will be indicated in the context.

Whether written or mental, the complete plan will cover the scope of the Decision, and will be the commander's method of procedure for his future conduct of operations. A commander may, or may not, formulate his complete plan in writing, or embody it in a formal directive which will provide for the execution, in full, of the Decision of his estimate. He may find that his plan divides into several parts, and he may make separate provision for the execution of each of these parts.

While the integrity of a plan depends upon the soundness of its essential details, the plan is properly formulated as a directive or directives projected in detail, only so far into the future as the commander's estimate of the situation a.s.sures him of reasonable freedom of action (see page 57).
