And sorry for the reflexive newbie comment. LOL. I’ve been hardwired with skepticism lately.
I think is is entirely possible, and even likely to be assigned to the 75th Rangers without being a Ranger. This would make it proper to wear the 75th patch without the Ranger tab above it. So far as I can see, Hunter has not claimed to have been a Ranger, but mentioning his duty in 75th caused many (myself included) to assume he was. The Ranger units have need for non-grunt/Ranger MOS’s, and I doubt that guys that earned the tab would be very enthusiastic about working as a supply sgt, LOL.
