I’m telling you, the Russians are only following these drones so they can see what targets the drones might be flying over. It’s an old trick.
This is a prudent move on the part of the Russians. Those drones are armed and potentially flying very close to Russian troops. My guess is that the ROE would allow for the drone to be shot down if it got too close.
Interesting way the SU-34s were “inserted” in to Syria. Flying underneath Condor Flights (AN-124) with transponders turned off to avoid detection.
