Were you in a known "Robin Sage" area?
I don't think so since I did not think Robin Sage was done that far east. But it could have been. Since it was a Cobra it was more likely the Marines were out and about. I think the army had gotten rid of their Cobras by then and moved to Apaches.
Robin Sage is in the area we live. Pretty sure we have seen aircraft that had to be in a exercise and likely Robin Sage. One night I heard some aircraft coming in fast, low and loud. Got outside just in time to see two or three aircraft flying tree top height and hauling a...s. They were flying in train, and while I could not really see details, based on the size, what I could see, and engine sound, I think they were Osprey's.
For those that do not know, Robin Sage is a capstone exercise for soldiers training to be in the Army Special Forces, aka, Green Berets. The exercise takes place over quite a few counties around Fort Bragg. There have been at least two this year including one that is going right now.
I have recent heard/seen some copters flying a route that is unusual so maybe they are in Robin Sage. I heard some more copters in the wee hours of the morning but I was not getting out of bed to check on them.
The army announces the exercise so people, and especially law enforcement, know what is going on. Years back a deputy rolled up on a pick up truck with Robin Sage participants, who were armed. The participants thought the deputy was part of the exercise and two soldiers ended up getting shot by the deputy. One died.
