clude that the
capture of Y island would not constitute a sufficient contribution to
warrant its adoption as an operation at this time. Therefore, he might
omit this operation, or he might defer it to a later stage.
A feasible operation may similarly be rejected or deferred out of
preference for another which can more readily be accomplished.
The tests may also reveal important facts as to the relative
consequences with respect to costs. For example, two operations might
both be acceptable as to this factor, but one might be less acceptable
than the other. Accordingly, the less acceptable operation might be
omitted, or might be deferred for the time being.
Upon the completion of the tests, all operations retained are listed
for further development.
The Formulation of Tasks
The correct resolution of the Decision into the detailed operations
required is further ensured by the visualization of these operations
as tasks. Tasks so formulated (page 162), become a basis for the
preparation of directives.
To prepare a plan as a basis for directives, or for use as such, the
commander first finds it desirable to formulate and assemble the
various tasks. The tasks are formulated as a result of his study of
(1) those operations which do not require to be broken down, and which
may now be rewritten as tasks, and of (2) the component parts of the
more extensive operations (See page 162, bottom).
Each of the tasks, as now listed, is tested for suitability, for
feasibility, and for acceptability with respect to the consequences as
to costs. In view of the fact that the operations have all been
thoroughly tested, this process now becomes not a formal analysis but
merely a check.
The Organization of Task Forces and Task Groups
The commander now classifies the tasks on the basis of their
suitability for accomplishment by appropriate task forces or
subdivisions thereof, i.e., task groups. In so doing he endeavors to
avoid forming any more classifications than are necessary for the
accomplishment of the full effort.
Note: In the remainder of this work, the term Task Group, except as
may otherwise be indicated, will be understood in the inclusive sense
of either "task force" or "task group".
Tasks are assigned to task groups on the basis of such factors as the
nature and geographical location of physical objectives, the existing
disposition of the several units, their capabilities, and their
freedom of action. T
