Its been more than a decade since I got out, and I was only really trained in how to recognise hostile EW and take countermeasures. Mostly just switch frequencies. I know the good stuff is all spread-spectrum chirps picked up by satellite, but unless you're in DSD they don't tell you much more than how to use it.

Basically the military uses LoRa-but-better, and with a bird in the loop for unlimited range. How much better is anyone's guess.

I've heard Russia way outstrips us in EW technology, but IDK any details.
