As far as I am aware, a radio signal is basically just shouting into the void, and anyone who is tuned to the correct channel can hear you clear as day, like a car radio. So, how do militaries keep their radio signals from being over heard by the enemy? Do they have special radios, or are the communications sent over radios just not that important strategically?

One, the data of the signal is encrypted. Two, the radio signal jumps around on different frequencies seemingly randomly, hard to get the whole signal. Military radio operators “key up” at regular intervals so their radio knows the correct encryption and frequencies.
