eplenishment 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.

These problems give rise to the subsidiary plans previously referred
to (page 106). They are not necessarily subsidiary in importance; even
the Battle Plan, the basis for the culmination of tactical effort, may
result from the solution of a subsidiary problem. The word
"subsidiary", as here used, merely indicates that the problem has its
origin in the commander's own Decision.
