Similar to the E-2 question, how would you react to a young 2LT who is being unprofessional with a strong sense of entitlement?

Same way I'd deal with anyone, delete everything they ever had done from MEDPROS!!!! I kid! I would remain professional find out who their commander was and inform them of what happened.

As it was previously stated general military authority gives the right to make corrections to anyone. Professionals will accept it, fix the issue and drive on. I have noticed a 1SG who had some craziness happen, they thanked me for letting him know and took care of it.

Chances are, in the commissary, there will be someone of higher rank than him. As soon as I spot that person, I would let them know what transpired and then point the way. Then I would probably get some popcorn and watch the show from the side.

Sir, if we're taking your example, you could pull him aside and remind him--backed up by your rank--that he is in the wrong. I on the other hand can respectfully (keyword folks!) point out the correction to be made, and either the officer will do the right thing or they will not. Either way, as enlisted, I have done not only what I should do, but what I can do.

I never had any reservations about making uniform/appearance corrections, even to our battalion commander! Back then it was actually a kind of game to see who could correct the highest enlisted and officer rank. Sure our motivations may have been a little questionable, but we were not "wrong" for doing it; and it caused us to tighten up our own appearance, because the last thing a guy wants to do us correct someone who outranks them only to have that person turn the tables and point out that THEY are wrong!

I give the my name and unit and request the same. Then I tell them I will be in touch with their commander, and if they want to, please contact mine- but I will be briefing mine the second I leave that 2LT.

I've been in something of a similar situation.......
While at a special event to present the colors, our assignment was to have each team member in a different uniform BDU, DCU, ACU, Class A dress greens, and the Ceremonial dress blues.
A 2nd LT. apparently he didn't like that idea, he kept telling me that it wasn't authorized by regulation, so I politely asked to which reg he was referring to, and it came as no surprise that the LT said that he didn't know and that he just knew it wasn't allowed for 5 different uniforms to stand together.
I then politely told him AR670-1 said that there will be no mixing and matching of parts of one uniform with another uniform, I also told him that does not include 5 different uniforms with 5 different soldiers wearing them.
Needless to say he refused to listen to an NCO who had been doing Honor Guard for more than a dozen years when the LT had only 2 years in prior to being commissioned.
So it be came a stand off with the LT pitching a fit over it, the LT made several phone calls to Senior NCO's who were in admin and they all told him the best person to ask was the NCOIC who was at the event because he knew the reg and was certified at the P.E.C. Honor Guard Course.
The LT after the 6th or 7th call and getting the same answer had an adverse reaction and looked at me and said they all gave me the same answer to ask you.......
The LT then said that he would therefore counterman me and make the final say so. Big mistake for him, I then told the LT since it was now his word and order not to allow the team to perform at the event he would be the one to explain to the requester why the team did not perform.
Later that night the requestor and the State Governor asked me what happened and I respectfully told them please ask the LT he gave the order.
The next day my NCOIC and 1stSGT called me in and told me that the requestor and the State Governor called and made a complaint and the CSM was extremely livid and wanted heads to roll so I explained to the 1stSGT and CSM what happened and I was sent on my way later I found out the LT had had his butt handed back to him along with his butter bars on a silver platter by the Battalion Commander and the CSM with a formal reprimand on his record at the request of the Governor.
Moral of this story is NCO's should always lead the way and train the new butter bars to listen and follow the experienced NCO's and learn other wise those I know everything butter bar know it all's will get sent back with the small children and delinquents who think the same way just because they wanted to jump in over there head and get that bar which doesn't guarantee them to be all knowing once it gets pinned on. NCO'S lead from the front and teach your new LT's so the don't end up like the LT that got himself in over his head with the Battalion Command and a Governor. And please no matter how much it hurts you to be to the one who knows the regs because your supposed to doesn't mean your gonna be able to stop a new LT or a pvt2 from shooting themselves in the foot perverbelial way cause there gonna do it anyway just because they have to test the waters for them selves to learn it may take a few times and may take a cranky CSM and Battalion Commander to set them straight and when that happens short leashes come to mind to help correct the problem along with a cork under the nose to help the learning and training process.
NCO's lead the way and know they are more professional and knowledgeable.
If a correction has to be made on the spot make it quick, direct, and to the point and quietly and not embarrass anyone in front of others be polite be professional and they will follow while you the NCO leads the way and set the example but if they are still bent on going and doing a thinking they are above the S.O.P. or policies and you did you job to try and correct the problem you have done your job and it is now their failure for not complying with policy.

Sadly, not all 2LTs are that sharp. However, at some point his troops are going to do "exactly" what he tells them to do, which will probably not turn out the way he wanted. Karma will nip him in the pants, so as an enlisted soldier, learn from his poor example, and know that he's going to need the support of the people he thinks he's above to succeed. Hopefully he'll change his ways. OR -- if he's "your" LT, have a talk with the 1SG. They have shaped many a wayward LT in the past, and will do so many times to come.

I was at pilot graduation for my son at Ft Rucker. His stick buddies dad was a BG and wore his uniform to the graduation. We had met before at a couple of activities during the 11 month course. Our kids were taking some advance training. After wing pinning etc we retired to dining room for lunch and the Bg was sitting across from me. I looked at him carefully and something was looking funny. Closer checking reveals' one of his ribbons has slipped off his rack. I pointed. it out for him. we looked and couldn't find it close to where he was. He was embarrassed but no one else all day told him his class A uniform was messed up. Even his sons and daughter noticed his problem all were military officers . He fussed at them for not pointing out his GIG. He bought me a extra desert.

First, I would forcefully explain to the 2LT that by doing what he/she was doing, he/she was making it impossible for him/her to be an effective leader. Second, I would emphasize to the 2LT how difficult it would be for him/her to succeed in the unit without the support of the SNCO's and NCO's, and that ignoring their sound counsel and mentorship was the fastest way of losing said support. And finally, if he/she did not immediately remove the headphones, I would ensure that the COC was duly informed that the 2LT was of the opinion that the rules didn't apply to him/her.

I like what 1stSgt Glenn Brackin had to offer but the a-hole side of me still want to say "Okay, sir." and let him continue on his way because I have no doubt that he'll run into someone like a 1SG, CPT, or higher and then get his butt handed to him/her. Maybe that will be the lesson he/she needs to realize that input comes in all forms and sometimes it's better to listen than to speak.

I was a 1LT and asked by a Captain (also a doctor) why I didn't salute him. We were standing in the middle of the street in our compound and he has no hat on. I told him that I would treat him like an officer when he started acting like one and walked off.
Not just 2LTs who feel entitled.
