I’m vaguely recalling the Serbians jammed GPS during the Balkan wars of the 1990s.
Yep, the Russians have adapted steadily since Pristina Airport.
Yes.
Russian army guys put on Serb army uniforms and, as a group, had their picture taken in front of all kinds of outstanding military equipment.
Apparently the US got ahold of the pics and were worried about NATO attacking for awhile.
Yes, but next they will have flying robots, jammers to jam the jammers.
