Yes, he was RFS'd while in one of the battalions. IIRC, he never went to Ranger school, just RIP when he was enlisted. And since he deployed with one of the battalions, he is entitled to wear the scroll. Keep in mind that Ranger units deployed on ad hoc short term basis, meaning week(s) to a couple months. Not year long, like Big Army units.
It's also my understanding that he used his combat scroll to deflect criticism and that he traded on that scroll to get his appointment.
Either way he had 5 years of info on his FB page, so it wasn't in his senior year that he suddenly converted. He should have been booted long ago..
