As much as I'd like to say this is something, it is not. These Aircraft are common occurrence at FHU, and can be seen every week. FHU is a Training Base for many things MI related, and the area the Aircraft is flying in now, and an area to the north of FHU, Benson, AZ, are Training routes. I have seen these Aircraft (real time, Eyes on) flying from FHU and sometimes they are NOT using these Call Signs, or on rare occasion, they are not even able to be seen on ADSB.
Remember, if they don't want to be seen, MIL Aircraft can turn off the ADSB portion of their Transponder/IFF, unlike CIV Aircraft, which have to have it turned on.
Pic is a recent CAP of one that was on a Route, just north of Benson. The roads there are I-10, here it intersects with SR 90, which heads south to FHU and Sierra Vista, and further south.
Interesting CAPTCHA for this post, KEK.
