Heck even in combat there are restrictions on blacked out ops. Only unit I know of that does it on a regular basis is 160th. To do blacked out ops, even covert lighting (IR) at a public airport with no NOTAM and no comms would be flat out hazardous.
As far as training at a civ airport, well...
Military does its own flight checks as well for tactical gear. Depends on how the system will operate. We had an FAA Flight Check for our ATC gear in Thailand because it was going to be used for IFR ops. We also had military Flight Check for small scale exercises for VFR only ops.
Actually flew...
I was just reading about Audie Murphy today. Never realized he died in a 680 crash in VA.

Taxiing out for take off but yeah doesn’t look like anyone in the back either. Taken right after my first flight in country. Heard the distinctive sound of a Prowler behind me and snapped a shot.
