These tests may frequently be of a routine nature, by reason of the previous painstaking tests of the several operations involved. However, such final tests cannot be omitted without incurring the danger of selecting incorrect objectives for subordinates to attain. The Assembly of Measures for Freedom of Action Having completed the classification of his tasks, the commander next assembles the measures determined upon as necessary for ensuring adequate freedom of action. When the subject matter is not too bulky, these measures are incorporated in their proper place in the basic plan. Otherwise, instructions as to these matters will be issued as annexes. The various measures are assembled under the classification shown below: (a) Measures required for security, for cooperation, and for intelligence activities. (b) Measures for logistics support. These cover provision for procurement and replenishment of supplies, disposition and replacement of ineffective personnel, satisfactory material maintenance, sanitation, battle casualties, and the like. (c) Measures for the exercise of command. These include provision for communications, location of rendezvous, zone time to be used, and the location of the commander. This classification corresponds to that used in the Order Form (page 193). Experience has indicated that such a classification facilitates the transmission of instructions to subordinate commanders. If desired, the material which will be required to be incorporated in paragraph (1) of the Order Form (see pages 190, 191, 219 and 221) may be also assembled at this point. The Preparation of Subsidiary Plans As previously noted (page 106), certain subsidiary problems require the preparation of subsidiary plans to be included with the directive as annexes. In broad strategical estimates, the solution of such subsidiary problems involves a vast amount of mental effort; even in restricted estimates, these problems may require most intensive thought. It is therefore appropriate at this point to discuss, in some detail, the nature of these subsidiary problems. During the solution of his basic problem and later, during the process of evolving his basic plan, the commander may become aware of the need for further action of a supporting nature with respect to his basic mission, distinct from that which he intends to assign as tasks to subordinate commanders. If the nature of this action involves perplexity, he will be confronted with new problems to be solved. When he recognizes that such problems exist and are to be solved by himself, this awareness is a recognition of the incentive. For example, one of these problems may involve a battle in which the entire force will participate, or perhaps a sortie requiring coordination of the several subdivisions of his force. Others will be concerned with measures recognized as necessary for ensuring freedom of action.
