the convoy has to slow down and is likely to bunch up. An ideal location would be a curving hill that
has high slopes on either side.
Mine Activity. Even in rear areas, mines pose a major threat to the lines of communication (LOC).
They are easily laid by saboteurs, sympathizers, or guerrillas. Great care should be exercised, and all
of your personnel should be reminded to keep a watch out for mines. Your patrol should also be alert
for sites the enemy might choose to mine in the future.
Areas of Cover/Concealment. All areas that you observe which provide the enemy with cover or
concealment should also be noted. These may or may not be good ambush sites. Areas of cover and
concealment may also provide areas in which the enemy can move undetected. Equally important,
such sites may also provide protection and concealment for friendly vehicles using the road.
NBC Contaminated Areas. Your mission order should have told you the likelihood of encountering
contaminated areas. Based on that information you should have determined whether and what type
NBC monitoring equipment the patrol should carry. Even in areas where the likelihood of contaminated
areas is low, you should always be alert for them.
The types of intelligence information that you should gather and record are limited only by time. Every
item has some value. When you are in doubt, record it.
Recording/Reporting Information
No matter how well you gather the information, it is of little use if it is not in a form to be used by others.
Additionally, it is impossible for you to remember all the information. As you proceed on the patrol, you
must keep an overlay.
A map overlay is a drawing of a route and its characteristics. A sample overlay is depicted at figure 2-
4. The overlay should be prepared on transparent paper when possible. Although clear acetate is
often used for overlays, markings on it can easily be rubbed off inadvertently. Markings on paper are
less likely to be inadvertently damaged. The overlay must be accurate, clear, and concise. Standard
military, topographic, and overlay symbols are used to ensure that route reconnaissance reports are
universally understood.
