b. Time and date.
Any overlay should contain the latest possible
information. An overlay
received in time is very valuable to the planning
staff and may affect the
entire situation. An overlay that has been delayed
for any reason may be
of little use.
Therefore, the exact time the
information was obtained
aids the receivers in determining its reliability
and usefulness.
c. Map reference. The sheet name, sheet number, map series number, and
scale must be included. If the reader does not have the map used for the
overlay, this provides the reader the information necessary to obtain it.
d. Author.
The name, rank, and organization of the author,
supplemented with a date and time of preparation of the overlay, tells the
reader if there was time difference when the information was obtained and
when it was reported.
e. Legend.
If it is necessary to invent nonstandard symbols to show
the required information, the legend must show what these symbols mean.
f. Security classification.
This must correspond to the highest
classification of either the map or the information placed on the overlay.
If the information and map are classified, this will be so stated.
The
location of the classification notes are placed in the upper and lower
center of the overlay. See Figure 2-11.
