Remote Control and Military application

I don't think you understand the whole magnitude of radio channel vunerability. There's no such thing as reliable radio channel whatsoever, it doesn't takes sophisticated equipment to completely shut radiocommunications - which is why russian radiojammers from 70's are still in use: because they're still very effecient. Modern radiostations can not only selectively jam enemy transmissions, they can also destroy/disengage enemy raido equipment with targeted EMPs, and they can intercept radio transmissions, and even fake out transmissions to sabotage enemy communications even worse. During my short military service I've been an operator of such device, which was a combination of laptop, amplifier and antenna. It was more of a scouting device that was capable of detecting and locating signal as weak as civilian cell phone (or even wi-fi signal) within several miles radius, precisely enough to target an air strike. Truck-based radio stations having working radius of several tens of miles and higher, and accordingly higher power. Like those things in Red Alert game, except for real.

In case it wasn't obvious, these devices can sabotage ANYTHING that radio-controlled, ranging from cell phones and radios to guided missiles.

And wired channels are subject to sabotage since forever.
