This UAV actually doesn't use the military M-code, doesn't need to.

The military one usually have a pilot.

Nope, they use the same daylight camera (and it is a vis-light model). The commercial and mil-spec radios are different, but mainly in power and freqs.

This UAV usually has a pilot controlling it, not an autopilot.

ScanEagles crash, and this one likely did in the water (no prop damage). I can assure you they didn't "trick" it to land as it requires a closed loop data stream to catch its arresting wire correctly. The UAV does have the ability to return to base unless GPS signal is lost.

The only difference between commercial and military is the radios, no way to tell externally.
