He probably never will. The 7th Grp picture he pretends is his is an ODA from the mid-'80s. We've identified all men in the picture. It also looks like he added a Ranger Tab to his website. He's never before claimed Ranger so this is strange.

He and Mike Mika (President of SFA Ch 34) threatened to sue the SFA National if they didn't rescind the letter they sent us, give Rudi a formal apology, and re-instate him as a member in good standing. Of course SFA National refused and nothing came of his idle threat.

Mike Mika has twice, along with Rudi Gresham the fake Green Beret claimed that Rudi spent 12 years in the S.C. National Guard and that's where he attained the rank of LTC. Neither time were they able to produce records that baked up that statement.

I just looked at his personal website, and it still has a picture autographed by General Yarborough, and a statement that says he served as Yarborough’s Aide. When will this clown give it up? I took screen shots.

Rick Upton:

Why is he working for the VA?


First of all, thank you folks for what you do, what you’ve done, and what you’re willing to do.

Secondly, it is my hope that Mr Prouix owns up to his lies. I have been watching this story and it disgusts me that there are people who would assume to receive the accolades deserved, but never sought, by better, braver, stronger men.

Mr Prouix needs to be exposed. Well done.


This is almost unbelievable. This guy wanted to be a Green Beret so bad he faked it to the grave. It must have been awesome to him to take on a persona. Feeling like a hero, getting recognition, and being treated like a hero in addition to fellowship with real warriors was too much to pass up. It must have felt good. I'm sure he could have joined the military. He just didn't think it was worth it. He could have everything without dropping a single iota of blood, sweat, or tears. I feel sorry for his family. This guy is to me obviously mentally ill. I guess he never thought he would hurt and shame his family to the extent he ended up doing so. To any potential fakers. Let this guy be a lesson to you. If you want what we have, just join the military. Don't do this to your family and friends.


I just want to thank Guardians of the Green Beret. I had no idea this problem was so widespread. These phonies do a great disservice to all us real Green Berets. Yes, I am a Green Beret. They give a false representation of who we are, what we are, and what we represent. These phonies are almost always criminal otherwise in my opinion. Good job Guardians of the Green Beret. People probably don't realize what it would be like for me to ever actually meet a phony Green Beret. Offensive is not the word. I don't think there is a word for all the things that would go through my mind.


is that white shirt even a thing? i never knew that

Johnny O:

Ol' "Sarge" here talking all kinds of crap and stuff after he was exposed...LOL

Johnny O:

It's really pathetic that people try to get away with this type of stuff. I spent 23 years in the Army and retired in 2006 and although would have loved to to be a part of a Special Forces or Ranger unit and go through all of the training, never did it. And it just amazes me the lengths that people will go through to embellish military service.

Jacob Martin:

Question: There's a photo of him with two "fatboys" wearing berets, are either of them actually SF? The one in the middle sure doesn't wear his beret correctly (might be an officer)! lol
