Identification Information.
Certain information must always be included on the overlay.
Without
that information, the overlay is useless. Most of it can be placed on the
overlay before the patrol begins.
a.
Grid References.
There are two main reasons for including grid references on an
overlay. First, it allows you to orient your overlay on the map the same
way every time you use it. It does little good to plot the location of an
ambush site if the map doesn't indicate where it really is.
Second, when
someone else needs to use your overlay, the grid reference allows them to
place it on the map the same way that you did.
A grid reference on the overlay is represented by a +.
It is
created by laying the overlay paper over the map.
In diagonally opposite
corners of the map, trace where two of the grid lines intersect. Both the
vertical and horizontal inside arm should indicate the grid line. Magnetic
north should also be entered.
b.
Title Block.
In an available corner of the overlay, additional identifying
information should be entered.
You should enter your name, social security number, and
organization.
Should there be any questions about the overlay, or should
additional information be required, this allows the user to identify who to
ask.
You will have done so well that you will take pride in your work
anyway.
The date that the overlay was made should also be noted.
This
allows others to know how current the information is.
The final items of identification are the map reference and
scale.
These allow the user to be certain of the map being used for the
overlay.
c.
Overlay Data.
Now that you have completed the identification data, you must
place the overlay over the map and trace the route that you will
reconnoiter.
The start and end points are indicated by a "V," with the
point indicating the location. You also enter the total length of the route
in kilometers.
The last item of information that you will enter on the
overlay is the route classification formula. This is because it cannot be
determined until the recon is completed.
d.
A critical point is any part of the roadway that causes limits to
its use.
This would include road width, overhead clearance, or vehicle load
