r adapt the form to
his particular needs. In so doing, however, he bears in mind that
departure from orderly processes of reasoning, on which the form is
based, tends, through possible neglect of fundamental considerations,
to lead to the omission of essential features of the analysis.

On the other hand, a rigid following of the form may frequently cause
much repetition. This may be avoided, unless desired for emphasis or
other appropriate reasons, by reference back to preceding portions of
the estimate. It is also to be noted, however, that the Estimate Form
is adapted to a progressive procedure. Very frequently the earlier
consideration of some aspect of the problem can later be expanded both
in scope and in proper detail by reason of additional information
which has become available during the intervening stages of the
procedure.

The distinction between certain strategical and tactical problems
(page 83) may introduce variations in the handling of the Estimate
Form, and may affect the weight to be given the various factors. The
use of the Estimate Form, as described in Chapter VI, applies in full
to problems which embrace the complete scope of broad strategical
concepts. It is suitable also for problems of limited scope, for which
certain modifications or abbreviations are required. When applied to
problems of a detailed tactical nature, the emphasis on the factors of
fighting strength is somewhat different from that for strategical
problems. For certain subsidiary problems (page 106), the Form may be
closely applicable or may require considerable adaptation. In no case
is it difficult to modify the Form to suit the requirements of the
problem.

An estimate of a relatively broad strategical situation may normally
be reduced to writing, because time is usually available. On the other
hand, an estimate of a localized tactical situation frequently
requires almost instantaneous decision. Except in the preparation of
plans to meet contingencies, such an estimate can rarely be given the
elaborate form frequent in estimates of situations which are broadly
strategical in nature. When such tactical plans are prepared well in
advance of the event, the commander bases the estimate upon various
assumptions as to the circumstances of a probable situation.

The written solution of tactical situations under various assumptions
is a valuable feature of training to this end.

During the second step, i.e., the resolution of th
