In this study the commander will often find it necessary to divide
some of the more extensive operations into component parts, suitable
for later assignment as tasks for subordinates. Fundamentally, there
is no difference between an operation and a task, except that the
latter includes also the idea of imposing on another person, or
assigning to him, a definite amount of work or duty (page 84). At this
stage, then, the commander deals with components suitable for
performance by available weapons, in the usual units, or combinations
of units, in which they are effective. Of course, when an operation
meets this requirement without subdivision into components, it need
not be subdivided.

These component parts are not yet actually tasks, because the
commander does not plan to assign them at this time to any one for
execution. However, the components are visualized as clearly, and are
formulated as definitely, as is possible at this point. The
requirement is that they be acts that available forces can perform.

The method of breaking down an operation into component parts is one
of analysis and deduction. Having visualized the manner whereby the
operation can contribute to the accomplishment of the effort, the
commander has now to determine the means to be employed to this end.
Experience and knowledge tell him what numbers and types of ships,
aircraft, and other weapons, if properly employed, will attain the
effect desired.

Each component part will indicate both the action and the physical
objectives of the action. For each component, the commander estimates
what forces are required. He knows the extent of the armed forces
available, and he can, if his total force is adequate, adjust matters
to allow each component a force capable of carrying it out.

For example, a component operation might call for a search by
destroyers, but the commander might find that his destroyers were in
such poor relative position as to prevent them from reaching the point
of origin in time. Therefore he would be unable to conduct the search
by using destroyers alone. He might now consider a search by aircraft.
A study of this proposal might indicate that it could be carried out
in part by aircraft, but that available aircraft were inadequate to
carry it out in its entirety. In such event, consideration would be in
order of the possibility of conducting this search by use of other
forces also, e.g., submarines and cruisers.
