Can anyone explain if this guy I know is pretending to be a LTC?

Yeah he is full of bs. 101ST Airborne is Active duty.

1) 101st is an active duty unit...not Army Reserve.
2) The only Nurse Corps Billets in an Infantry Division are Brigade Nurses (CPT Slot). Unless he's an NP then maybe a drug deal was cut for a BAS, but I doubt it.
3) With a BSN he is almost certainly coming in as a 2LT. He would never be a LTC with a BSN. A Master's Degree is a discriminator for people who worked their way through the ranks. For someone off the street, it's not happening.
Sara, I hate to tell you, but your old friend is FOS.

Let's critically analyze this knowing that AMEDD does bring in people and give them constructive credit on rank... sometimes even up to COL... based on civilian education and experience in that field.

First, he's a nurse. Constructive credit is given to nurses. I went through OBC (now BOLC) with some nurses who were given the rank of O4 based on constructive credit, and they achieved O5 shortly after OBC.

Next, the word "just". That is not a well defined term regarding timeframes. Just could be a day ago, a week ago, even up to a year ago. The question is, how long ago did he join?

A BSN. Frankly, with the Reserve you could be a LTC with just a BSN. Compo 1 looks more at MSN RNs for LTC. But a BSN in the Reserve is possible, along with constructive credit work history, to be a LTC.

Additionally, what kind of RN? Is he a run of the mill 66H, or is he more specialized as a 66E, 66F, etc.? Those AOCs only require additional certification. If he is a specialized RN, he could be a LTC as long as he has the constructive credit. It actually makes it more likely that he was given constructive credit.

Yes, the 101st is a Compo 1 unit by command. However, there are Army Reserve units which support specific Compo 1 units and, therefore, also wear that patch. So this is still a possibility.

Finally, not on AKO or Enterprise. That's where I get suspect. AKO and Enterprise are a requirement. This could also help define the timeframes of "just", as stated above.

Do this, tell him you think you have an opportunity for him and would like to get his name over to your S1 for consideration. Give him your enterprise email address and tell him that you can only discuss this opportunity with him through official government channels, that a response from him can only come from another mail.mil account. Sometimes it takes a little bit to get enterprise email established for new Soldiers. He may surprise you and actually send that email. If he does, ask basic questions like his AOC, BOLC grad date, etc. Tell him you are passing the info to your S1, and then give it to the S1 to see if there is an opportunity. If there is none, say that there isn't at this time, but if there is one then you just helped a Soldier out.

If he sends you information over any other email, then you can be pretty certain he's lying and you can call him out on it.

Ask to see his ID card. Simple. If he doesn’t have one it’s BS.

Friend of mine is a Veterarian. Direct commission as a Major ( the Army is hurting for Vets). I would say BS on his story. She’s a DVM, he’s a nurse.......

That would be an insult to fish. I do believe he has a BS in more than nursing, ask to see his ID card for the reserves they use to be red with exploration date and rank.

The is no 101st reservist that I know of, and the highest he can come in with a BS in Nursing is 1st LT., unless he has a high specialty which may warrent Captain... But that's it.

He’s a no-go. If he were in the USAR, he’d be listed in the AKO white pages. Also, direct commissioning as a LTC? I don’t think so.

Why do posers pretend to have any MOS, Rank, Badge, or Award?
Just my opinion but they are either suffering from Dementia or they are trying to make up for a shortccomming in the life.
Did I get every assignment I wanted in the Army? No, but I served when others didn't.

Quite simple, say to him "Prove It."
