 Larger UAVs, which could be under the operational control of the SR team, could use additional sensors including portable acoustic and electro-optical systems.If there is a ground SIGINT requirement deep behind enemy lines, an appropriate technical detachment may be attached to the SR element.For SIGINT operations, the basic augmentation to United States Marine Corps Force Reconnaissance (Force Recon) is a 6-man detachment from a Radio Reconnaissance Platoon.
