(Purpose) in order to deny to the enemy the use of the only available base site in the area ABCD.
This mission is identical with the decision, linked to its purpose, of the preceding subsidiary problem.
Subsidiary problems relating to training ([page 160]), when solved by the procedure distinctive of the first step, involve estimates of the situation very similar to those explained previously (Chapter VI).
Section I-A of such a training estimate will include a summary of the salient features of the existing situation, from the strategical or tactical viewpoint, together with a statement of the salient features of the operations to be carried out for which the projected training is designed. The incentive will be found in a previous decision calling for the operations which require the training to be given. The assigned objective will be the making of adequate provision for training appropriate to the projected operations. The (subsidiary) mission will be:—
(Task) to provide appropriate training,
(Purpose) in order to contribute to freedom of action during the operations contemplated. (In each particular case the operations contemplated will be indicated by proper phraseology in the mission or by reference to the preceding summary of the situation.)
Section I-B of a training estimate will take account of the training factors cited in the Estimate Form (Chapter VI) for a basic problem, but will specify details with respect to both own and enemy forces. This section will also cover existing facilities for training, as well as the characteristics of the theater which have now or may have a bearing on the training to be given.
Section II will discuss the various possible procedures for affording the appropriate training.
Section III will deal with any measures which may be adopted by the enemy (through actual attack, through propaganda, or any other methods) to hinder or prevent the desired training.
