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

As fishy as a 4 day old dead carp on a 100 degree day...

This story more than smell fishy. It is a big pile of male bovine excrement. The 101 is not a reserve unit.

Just saw the pic above. He’s about as fake as it gets. All I had to do was take a quick look at his awards. That’s usually the dead giveaway.

I’m going throw the bulllshit flag here. Even if he has a BS in nursing, he wouldn’t direct commission higher than O-3 at the most. Second, only way he would be Reserve and be assigned there would be as an IMA Soldier since there are no Army Reserve Engagement Cells (ARECs) At Division level. Not to throw down a gauntlet, but I would get Stolen Valor to check if it really concerns you. Better to have them find out before he jams himself up.

Im pretty sure the cutoff for joining is 34.

Usually advanced officer rank would be granted for the more advanced degrees, for example I think my mom got a similar offer as an OBGYN doctor. But to answer, if it's a "new" situation, it may take a bit to catch up. Does he have a CAC yet? Just saw a good catch from others, yeah 101st Airborne is an Active Duty unit. I was in 101st Engineers (a National Guard unit) so it didn't set off the alarms at first. I'm calling BS.

Call MEDCOM and ask your question. At first glance it seems dubious. But, MEDCOM and JAG are their own animals. He could indeed be a Reservist on Active Duty and stay on orders for several years. It depends upon the needs of the Army.

If nothing else, always remember this quote from Yours Truly:
"Absolutely nothing in today's Army is absolute!"

Fake news

Smells fishier than a 3 week late to port tuna boat

Fake, get on his butt and put him in his place because you have a gazillion brothers watching your back.
