Britain’s Royal United Services Institute and the US’s Pentagon have acknowledged that Russian electronic warfare is reducing the accuracy of American guided weapons, including JDAMs and HIMARS rockets:
In particular, Withington pointed to the Russian Army’s R-330Zh Zhitel, a mobile truck-mounted jamming system specifically designed to disrupt GPS and satellite communications in the 100 MHz to 2 GHz wavebands. “Signals from the U.S. GPS satellites which JDAM kits use are transmitted on wavebands from 1.164 GHz to 1.575 GHz,” according to Worthington. “These fall squarely within the R-330Zh’s catchment area.”
Worthington claims to have seen official documents that put the R-330Zh range at 18.6 miles, with a 10kW-strong jamming signal. This is “notably stronger than the strength of the GPS signal arriving from space,” he noted. “Moreover, the closer the GPS receiver is to the R-330Zh’s jamming antenna, the stronger the jamming signal becomes.”
In theory, the Selective Availability Anti-Spoofing Module upgrade to JDAM in the early 2000s should ensure that JDAM will only respond to authorized M-Code encrypted military GPS signals. However, Russian jammers may still be able to disrupt the signals through “sheer brute force” jamming beams, Withington said.
Russia could also intercept M-Code signals and retransmit them with slight alterations to a JDAM, causing the bomb to miss. Efforts to bypassing Russian interference by using signals from multiple GPS satellites could in turn be countered by employing multiple jammers.
Russia’s counter-GPS efforts are part of a massive electronic-warfare campaign that has also disrupted Ukrainian radio communications and drone operations.
Russian forces “now employ approximately one major EW system per 10 kilometers [6.2 miles] of frontage, usually situated approximately 7 kilometers [4.3 miles] from the frontline,” according a recent RUSI report on Russian tactics. This jamming has contributed to a Ukrainian drone loss rate that RUSI estimates to be as high as 10,000 UAVs per month.

Nonetheless, Russian electronic warfare has limitations. Emitting jamming beams discloses a jammer’s location, and Ukraine appears to have located and destroyed Russian systems such as the R-330Zh. Ironically, smothering the airwaves with powerful jamming beams may also be disrupting Russian GPS and radio communications.
None of that has really changed in 40 years, except that now jamming is even more effective due to the dependence on GPS and drones. The Russians have believed in both active and passive EW all across the battle space for a long, long time.
If only this were known before!
Like say 2018 exactly Karber at modern war institute go to 36:50 for EW.

Also known, CYBER is an annoyance, really a JOKE.
The Western money went into CYBER $$ and EW went away for us, because like people got scammed or hacked at TARGET and like that’s war, also Finance pays more, and you gotta always work for the next job [never the job you have]…
Not jamming artillery rounds’ electronic fuses 400 meters from impact.
Not 10x10x10 drills.
10 minutes to acquire
10 mins to fire
10 mins to displace.
