Looking a little further, I found this:
snip only....very informative page:
Training was a combat misson for volunteers. Volunteers were assigned, not accepted in the various Ranger Compannies, until, after a series of patrols, the volunteer had passed the acid test of a Ranger, Combat, and was accepted by his peers. Following the peer acceptance, the volunteer was allowed to wear the black beret and wear the Red, White and Black scroll shoulder sleeve insignia bearing his Ranger Company identity. All Long Range Patrol Companies and 75th Ranger Companies were authorized Parachute pay.

also, from further on down the page, I see that it was Co. F, 52nd Infantry (LRP) that I am remembering present when I was there, as “Co I (Ranger),75th Infantry/1st Infantry Division/1 Feb. 1969 - 7 Apr. 1970” is after my personal frame of reference (July 67-Jul 68). BTW, this page talks about “black berets”.......I don’t recall any black berets until shortly before I got out Jun 1975......I DID see a few worn at Camp Casey about then.
I was with F/51 (LRP) from Sept of ‘67 until the company was split up to make room for D/151, an Indiana National Guard LRP company, when I went to O/75, with the 3rd Bde of the 82nd, in February of ‘69. At that time, we went from being LERPs to being Rangers though nothing changed in our mission and we weren't officially authorized the black beret. I don’t know any LRRP/LRP/Rangers who wear the tab without having gone to Ranger School, but you never know these days.
I’m curious as to whether he served on a team but, at this point, I don’t see any real alternatives to Duncan Hunter and I support him.
