Then again, with a traditional analogue AM or FM radio it's trivial to triangulate the position (and possibly call in an artillery strike on said coordinates or whatever), as well as jamming it with a narrow-band jammer.
And without some hw/sw assisted crypto, communication becomes a lot slower. Or then you accept that the enemy can and will overhear what you say.
So for better or worse, complex radios based on digital technology is necessary for modern military use.
Though I wonder whether it would be that useful today, with the state of voice recognition and machine translation technology? Just because you throw away those fancy digital radios doesn't mean that your enemy will forgo modern tech. ;)
