FM 17-98 SCOUT PLATOON

Redundancy. The platoon leader may task more than one element to observe a particular assigned NAI or avenue. He
does this based on the nature of the NAI or avenue in terms of size, terrain, or importance. For example, a very large
avenue may require multiple observation assets to ensure all aspects of the avenue are covered. Terrain that is very
broken or mixed with areas of thick vegetation may require more than one asset to ensure that adequate continuous
coverage is achieved. Finally, if a particular NAI is assigned significant priority by the commander, the scout platoon
leader may assign multiple elements to cover it. Redundancy not only ensures that an NAI or avenue is adequately
observed, but also enables the unit to accomplish the mission even if some assets are compromised by enemy forces.
Figure 4-3 illustrates redundancy of observation assets.

Cueing. Cueing is a technique the scout platoon leader can use to cover an NAI or avenue when assets are limited and
he lacks the capability for redundancy. He plans contingency tasks that will increase surveillance on a particular NAI;
his surveillance teams execute the tasks when "cued" by activity at that NAI.
The NAI or avenue is covered initially either by a single surveillance team or by a remote or electronic signaling
device such as a trip flare or the platoon early warning system (PEWS). When activity is detected, other teams move
into preselected positions to add their capabilities to the surveillance of the NAI or avenue. Refer to Figure 4-4.
