Bottom line, you can strangle the ADS-B functionality when necessary, just like you're likely to strangle M3 over hostile territory. If the FAA ever goes to a no-radar, ADS-B tracking system, DOD will have to figure out a better way of filtering what gets broadcast other than position info. What's funny is that one of our aircraft shows up as an Air Force plane via ADS-B because nobody changed the registration info when the USAF transferred it to the Navy. What shows up on Flight Tracker Apps depends on what info is provided to the FAA.
