e of issue: that is, the month, day, year, and
hour; for example, July 12, 1935; 1100.

In the upper left-hand corner in the following sequence:

(e) The file notations and classification: SECRET or
CONFIDENTIAL, the classification being underlined and
spelled with capitals. This classification is repeated on
succeeding pages,

(f) The type and serial number of the directive, such as
Operation Plan No. 5, the words Operation Plan being
underlined. This is repeated on succeeding pages.

The Body. The task organization, which consists of a tabular
enumeration of task forces or task groups, the composition of each,
and the rank and name of its commander, is the beginning of the body
of the directive. It is customary to omit the name of the issuing
officer from any task force or task group commanded by him. Any unit
included in a force named in the task organization is, by virtue of
that fact, directed to act under the command of the commander of the
specified force.

When so desired for additional ready identification, task forces and
their subdivisions may be numbered. In our naval service, systematic
methods for such numerical designation are indicated from time to time
by proper authority. Numerals for this purpose are entered in the task
organization to the left of the title of each appropriate task force
or subdivision thereof. The numerals may be placed in parentheses.

The directive is addressed for action solely to the commanders of the
task forces or task groups listed in the task organization.

Train vessels assigned exclusively to particular combatant task forces
are listed among the units of those forces in the task organization.
If the directive is to be used for assigning tasks involving
strategical or tactical movement directly to the Train, or to any
Train units, such units are grouped together to form a separate task
force. If instructions to the Train are to be issued in another
directive, the Train need not appear as a separate force in the task
organization. As a matter of general custom, the Train is usually not
included as a task force unless it is to accompany, or act in tactical
concert with, some one or more of the combatant task forces listed.

Each task force named in this table, together with its numerical
designation, is preceded by a separate letter, (a), (b), (c), etc.,
and its assigned task is set forth in a similarly lettered
