They are definitely not blasting gamma rays to bring down drones lol. “radio” is a specific range of frequencies so “high frequency radio” is just frequencies at the higher end of that specific range.
Gamma rays are insanely dangerous. I’m too lazy to do calculations/research to back this up but I suspect that gamma rays intense enough to reliably drop a drone would also give cancer/radiation poisoning to anyone remotely downrange (and also the operators). Furthermore, I don’t think we have a way to produce gamma rays in any high intensity in the lab. matter-antimatter annihilation and fusion bombs are the only way I know of for humans to produce gamma rays. The former can only be done at atomic scale in the lab and the latter is, well, I guess that also destroys drones (and everything else within 100km)
I said this years ago after J6: if liberals wanted to maintain liberal democracy, they had to literally hang Trump after J6 and the false electors scheme. Instead he faced 0 consequences, so he (and the fascists around him) decided they could just keep trying different coup strategies until they found the one that works. Liberals let them iteratively test coup strategies.
