* Be positioned in areas which will not interfere with other friendly radars and supported unit missions.
* Accurately locating enemy activity is dependent upon how well the sensor is placed and directed.
Locations of GSRs, night observation devices (NODs), REMBASS, must be surveyed to the degree of
accuracy commensurate with the mission. GSR team survey support will not always be available. The
team leader must initially locate radars as accurately as time and equipment allow, using maps and
equipment organic to the team. As additional time, equipment, or location support becomes available,
accuracies can be improved.
Defensive Use. In the defense, surveillance equipment is employed primarily to maintain surveillance over enemy
avenues of approach, forward slopes of key terrain features, and to monitor possible enemy positions and
assembly areas for activity indicators. GSRs, and to some extent NODs, are generally deployed at the forward
line of own troops (FLOT), and forward to the combat outpost line with security elements providing observation
depth. In an economy of force role, GSRs cover gaps between units, monitor exposed flanks, guard possible
helicopter or parachute landing zones (LZs), and other critical battle zone areas. Alternate and supplementary
positions are established to provide maximum battle area coverage. Coverages are planned in conjunction with
barrages and final protective fires to determine when such fires can best be employed. They may also be used to
determine the optimum time for prepositioned munitions detonation.
Because the enemy may often attack at night, during limited visibility, or behind heavy smoke screens, GSRs are
of prime importance in defensive operations. GSR sighting information is integrated with all I&S means to
maintain current enemy status.
Patrol employment plans are closely coordinated with surveillance personnel. Prearranged signals and other
measures must be used so operators can distinguish between friendly and enemy elements. Such measures
may consist of friendly units following prescribed routes, swinging a canteen or helmet. Surveillance sections
employed to watch over an area in which friendly patrols are operating may locate enemy activity which may be
detrimental to the friendly patrol, and could alert the patrol to the enemy activity.
When employed during a mounted attack, GSRs may be vehicle-mounted and should move forward to overlook
the attacking force. However, GSRs do not operate effectively from moving vehicles. Upon objective seizure,
GSRs are displaced to the objective as soon as possible to provide enemy movement information while the
attacking unit is reorganizing.
