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

I've never known any 2LT's to be that disrespectful. They might disagree, but never be disrespectful. How about come up with a more realistic scenario?

I never knew any 2LT that would be that disrespectful. They might disagree but never have a response like that.

As a former 2LT, I always appreciated when anyone politely pointed out when I was not wearing the uniform properly.

Having dealt with this before, I will say that I have a boss for a reason. Now if no one is in immediate harm or potential loss of life then I am not about to lose my military bearing in the commissary. I have addressed the situation, if the Officer behaves in a way unbecoming of their rank then that is on them. But it will be addressed when I provide my boss (typically an O5 or above) with their name and a description of the transpired events. That Officer will be in front of someone that they cannot as easily blow off.

Try to inform his command."Doesn't apply ? lmao.

The Lt has mentors no matter how inexperienced he is or how young. His rank has a lot to do with his situation with the soldier. If he is in uniform on post or off post rules still apply. If he teaches his mentors and soldiers to do or act like he does he needs to practice what he teaches.

In addition to getting his or unit information I would ask where they earned that bar! Knowing that I would ask point blank if ANY of the officer of NCO instructors told them the rules don't apply to you? Sir or mam, I know this is new to you but it is the UNIFORM that says wether you can jam your tunes NOT wether you are "at work". I had the good fortune to serve under two STUNNING 2nd Lt.s (one OCS and one direct commission) who had a solid grasp of how things like that worked and when and just how hard to come down on screw ups. They also knew when and which NCOS to listen to hard and which ones were often a waste of time.

First of all, he would outrank me. I'd speak directly to his behavior and tell him that I'd find it very difficult to see him as a leader and worthy of my respect if he can't follow the same rules that I have to follow. I'd thank him for not being in my CoC and suggest he consider that SMs in his own line of leadership may feel the same as me. Those below him may not cooperate with his leadership and those above him may undercut him as a result of it. What if someone took a photo of him acting this way and sent it to his CoC? Not saying it would be me necessarily.

Tell him that he is a military officer, not a high school diva.

If he wants to play that game quote regulations, find out who is commanding officer is and tell them.

Do an article 138 on the LT
