Rockpicker, most such traffic would be secure, true, but once they leave VHF/UHF or get away from the SINCGARS radios you can never tell. As I said, I have heard a surprising amount of it in the clear. When you jump back to secondary networks or resources things often change drastically, including the application of encryption keys and who has what key.
cmradio, yes 6010 kHz is a BC freq, but I often run across other comms scattered in this band, as well as several other BC bands.
