6996 USB has been used for Red Cross nets in the past, but I don't know why they would have an authenticated net.  The net procedure had a definite NATO flair to it, but they're clearly not professional operators.

The digital mode sounds like MIL-STD 188-110A which would make me lean toward this being CFARS (given the "Q" callsigns) or possibly MARS, but doesn't sound like any MARS net I've heard.

0155 - heard callsign "Red Dragon Romeo", so maybe CAP? "Red Dragon" is the callsign for the New Jersey wing of Civil Air Patrol.
0201 - operators speaking over each other and an ALE sounding

This was a US Army MARS low power (QRPX) exercise.
