PLB Targets
PLB batteries are designed to have a 24 hour transmission life; so, if used for targeting it may be worthwhile repositioning them to the other side by counter drone, provided they are not booby trapped.
Large scale deployment of transmitting PLBs may saturate satellite and ground station capabilities; so perhaps better to turn off if not booby trapped.
The other effect of mass PLB deployment is saturation of 121.5 and 243.0. Is this RF intention, or unintended consequence?
Many PLBs transmit GPS location, but most drones already have that capability. Ultimately I am unsure how scattering of PLBs helps the orcs.
Speculation: The orcs could be collecting target GPS coordinates and using that to target missiles.
