How would you react to an E2 who "smart mouths" you in formation?

Call him in "AFTER" dismissed... then have a calm discussion about "REALITY"....!

Very nicely show introduce his face to my knee

Laugh and give extra duty and if it continues article 15

This is a simple one:
ALWAYS USE THE CHAIN OF COMMAND. And so, first, order said offender to report to your office, when summoned. This is done immediately in front of witnesses to avoid and confusion when said individuals may be called by a convening board for testimony if needed. Arrange for you supervisor to attend the planned counseling session with said offender. Document said offense to obey a lawful order, in writing, on an LOC (Letter of Counseling). Stick to the facts and remain completely objective when said subordinate is ultimately summoned to your office. When military member appears before you inform them why they are receiving a LOC and that their signature on said document is required in accordance with Military policies, procedures and the UCMJ. If need be, consult with 1st Sgt. and /or staff Judge Advocate for any legal guidance regarding UCMJ and MCM. During said LOC session with offender allow them to read the LOC narrative you've prepared, have them sign it (required) which merely shows acknowledgement of the documents existence and advise that individual they have to the right to provide, in writing, and mitigating circumstances that would explain their failure to comply with military customs, courtesy's, traditions and lawful orders. There's so much more. Basically, as this person's supervisor, you've taken the first step toward separating this person from Military service under less than honorable conditions. Their screwed....

I was a Senior NCO during my stint with the Army. If a Soldier had decided to disrespect me--especially in formation, he or she would be formally counseled. Also, there would be some "corrective action/training" going on. I would definitely write him or her up and when the time for the Soldier to be promoted, I'd ensure that he or she didn't get promoted. For the most part, whenever my Soldiers weren't acting like themselves, I would generally want to know what the underlying issue is prior to taking action. I would have to find out what was up with this Soldier for him or her to disrespect me. No doubt about it, I still would want to find out what the deal is prior to taking SERIOUS actions.

I was one of those arrogant pfc's . I learned my lesson by being sent to corrective custody and forature of pay.

Reassign the duty to someone else, then have the E2 do so much exercise and other things he would wish he had obeyed the first duty.

Suit up dip shit your the next one to go overboard and this is not a drill.

This is all these millineum generations. The way I see it he opens his mouth to upper NCO then he needs to get throat punched just for beING disrespectful. Didn't realize we have baby in the military now. You think if you were a POW that your captives wouldnt beat the sh!t out of you. If you don't follow a order. All I'm going to say the military is not a democracy it is dictatorship. The rules come from the top they need to be followed.

Smoke his ass!
