FIGURE 6. ZONE RECONNAISSANCE.
NBC reconnaissance elements should return from the objective area using a different route to avoid
ambush or observation (figure 7 on page 15).
Reconnaissance at Night and
During Other Periods of Reduced Visibility
NBC reconnaissance elements conduct operations at night just as they do during the day. The rate
of coverage is less, however, than one during the day. This is due to an increase in navigational
difficulties; a reduction in visual observation: and during sustained operations, a decline in human
endurance. As a general rule, routes can be searched just as well at night as in the day, although not
as quickly. When conducting a zone reconnaissance, zones should be narrowed since command and
control is more difficult at night. When performing an area reconnaissance at night or during other
periods of reduced visibility, the commander should also allow more time to accomplish the
