I still think it’s a group. So it could be all of them. But it’s definitely someone in close. Because when the anons have asked for confirmation. POTUS tweets. So it’s someone with clearance and very close to POTUS, Often Q uses the same verbiage as POTUS.
I’m with you. Our President is comfortable around military..(Possibly because of his early years in military school). The pictures in Japan and elsewhere leads me to believe there are others around the world and quite possibly using the Q post for other purposes too.
