Capabilities and Limitations. Although radar energy can penetrate light foliage and camouflage, smoke, haze,
rain, snow, darkness, it will not normally penetrate dense undergrowth, trees, and heavy foliage.
Heavy rain and snow will restrict radar detection capabilities. GSRs are generally ineffective against aerial targets
unless they are flying low enough that background clutter is provided by trees and terrain. GSRs are vulnerable
to jamming and other deception measures, and are limited in they must have area(s) of interest LOS.
GSR employment must be closely coordinated with REMBASS, patrols, listening post (LP), observation post
(OP), and with infrared (IR) light intensification, and aerial sensor devices to be completely effective. By using
GSRs, the field commander can increase fire support effectiveness and maneuver means.
The primary advantage of radar equipment is its ability to detect targets with accuracy when other surveillance
means cannot. While radar is primarily used at night or under poor visibility conditions, it may be effectively
employed during good visibility periods. The employment of this equipment should not be restricted to a certain
type of terrain, a rigid set of conditions, or a few functional operations.
GSRs can be employed in all types of tactical situations. GSR search and monitoring capabilities can be used for
a variety of tasks. These include--
* Searching avenues of approach, possible enemy attack positions, and assembly areas within the radar
sector for enemy activity on a time schedule.
* Monitoring point targets such as bridges, buildings, and road junctions for enemy activity.
* Monitoring and searching final protective fire or barrage areas to permit timely firing.
* Confirming targets developed by other such means as REMBASS or OPs.
* Extending patrol observation capabilities by enabling them to survey distant points or special interest
* Assisting unit visual observation during daylight hours by making initial target detection at great distances
which are obscured by haze or fog.
* Assisting in unit control during limited visibility operations. This might include vectoring friendly patrols
and warning them of enemy activity near their present position or along their route.
