During retrograde operations, the surveillance section provides significant enemy information which enables the
commander to decide the best method of withdrawal and the time to start the retrograde operation. During
retrograde operations, the decision to displace sensor equipment involves consideration of several key factors.
Secrecy is a primary consideration in most retrograde operations. GSR emissions may be detected by the enemy
so any withdrawal of GSR equipment from its location might compromise this secrecy. The commander must
weigh the requirement for maintaining surveillance equipment at positions as long as practical. GSR information
may aid in timely unit withdrawal by detecting the enemy advance and allow friendly units to withdraw without
becoming decisively engaged.
During movement to the rear, the GSR section may be used with the rear guard to assist in maintaining enemy
contact and determining enemy pursuit aggressiveness.
GSRs are generally employed on high ground to make maximum use of their range capability. Care must be
taken to cover the forward slopes in front of each GSR site.
Offensive use. The flexibility and maneuverability of the GSR section, coupled with its search and monitor
capabilities, make it a valuable offensive tool. During the attack, locations will often be determined from map
inspection and compass direction.
Properly and adequately employed, GSRs can assist in close combat by finding the enemy for the infantry. Local
security can be enhanced by using sensors to monitor enemy movement during and after the attack to give
warning of an enemy counterattack. GSRs may be employed to enhance all attack phases.
When GSRs are used with dismounted troops, they are normally operated from ground mounts. However,
vehicles should be used to transport the equipment as near to the selected site as terrain will permit. GSRs
should normally be employed in pairs to facilitate leapfrogging as the attack progresses to ensure complete and
continuous coverage within the attacking unit zone of operations.
During enemy counterattack, GSR teams continue to report information on enemy activity. By priority
arrangement, designated rear teams may be tasked to establish the location of friendly units on the periphery of
an enemy penetration. This unit identification and location may be a critical element in considering friendly
