Russia began to use wired UAVs, invulnerable to Ukrainian electronic warfare - NATO general
Russia has begun using experimental wired drones at the front. Their advantage is that the image from such UAVs is much clearer and they are not afraid of interference from Ukrainian electronic warfare stations.
Retired NATO General Erhard Bühler stated this on the air of the MDR Mitteldeutscher Rundfunk video blog, reports a PolitNavigator correspondent.

“Image quality should be much better for wired reconnaissance drones, which are apparently currently being used by the Russians in the experimental stage. For example, live video broadcast. I think this makes sense - such drones already exist, which are used by the Russians at the experimental stage...
It has advantages - in addition to the high quality you can expect, these wired devices have much less interference. That is, interference that could affect the RC drone's signals or even image quality,” Bullen said.
