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

If no personal issues (i.e., family death) the EMI that bitch to death. If that don't work send him to the pad.

I'd tell him or her, to fucking bad do what I tell ya. Then in private put the fear of God in their eyes.

As a Platoon SGT (E7) it is my job to politic for the betterment of my Platoon and than he Company. When confronted with said individual I dismissed everyone except the Asst PLT SGT his Squad Leaser and said soldier. Informed the NCOs of my expectations on the matter and instructed them to handle the situation the best way they seem fit. If they fail in correcting the situation than I would from punishing the individual to punishing the masses. Than I take money give extra shit details and than reduction in rank. And than when all else fails Discharged with othe than honorable conditions.

Set the example for all to see quick and decisive. Then make sure you take the time to council the Marine.

I would make an example of the E2 in front of the platoon/company and process formal charges under the UCMJ.

Bring the smoke.

Snapping knife hand and re adjusting said boot with an even worse job than he had that I shall supervise until properly completed

Make them change into pt gear. And pt their ass until they can't take it anymore. It's called training a young Marine. Giving them an education.

Um most of my family are marine or navy and back in there day if you got mouthy they put there hands on ya ! My uncle got him mouth busted open with the butt of a gun for not following a order

I would continue on with what I'm doing and then pull that Soldier out and have a "discussion "with them. You give them a choose, do the assignment or get written up. Also knowing me, I would want to know why they did what they did as well....Some times there's a reason why someone is acting out and I would like to dig deeper before I could possibly ruin someone's career. If this Soldier truly has an attitude problem then he or she gets written up in my book. I can't have Soldiers hurting my Platoon and moral.

Get the kill hat so he can do some damage

This would depend,on weather this person was part of permanent cadre, or he was under my command as a trainee..How I would react.In both cases,I would be hard pressed not to react with force.althought I know hands on would be wrong and illegal.??

Knock him out

What I would do in the seventies and what I would do today are two totally different answers. The reality is your actions depend on what the command expectations are for insubordination to an NCO.

Yea I agree with whoever posted throat punch...

I would simply tell them that they have failed at the art of communication and that he/she will not speak to me as such and an order was given. I will now contact my supervisor for review and they can return to their barracks until told to leave that area of face incarceration for failure to listen to a direct order.

Knowing that smacking the dog-shit out of him is not allowed any longer, I would find some extra duty for all of his shipmates say for the next week, or until his shipmates convinced him to change his ways. When I retired back in 94, the dirtbag would have had an upclose and personal session with me.

For starters let me say that my Marine Corps grunt mind CAN'T even imagine something like this to happen, and to bring it up for discussion and opinions! It's hard for me to comprehend that level of 1)Disrespect especially to that degree and telling him to find someone else!?!
2)Disobeying a lawful order from an NCO.

This isn't a babysitter "asking you to take out the trash"!!! This a superior giving an "ORDER" to carry out certain tasks. End of story. End of debate. Hello UCMJ!!!
The lame "having a bad day or bad news from home" does allow for this behavior active duty means 24/7 365. "Mommy" coddling is BS in the military. If these kinds of situations happen in the Army,Navy,AF,CG and even the Corps than they have FAILED in producing properly trained and disciplined military personnel.
Tact is important BUT this is an extreme situation that requires very extreme measures for these reasons
1)Such behavior is NEVER acceptable and will ALWAYS be dealt with quickly and firmly
2)The other personnel get a clear message as to the consequences of such behavior.

It is also important to have an All Hands meeting to stress that certain behaviors are never acceptable or tolerated.
It's not acceptable behavior from my children, and it DEFINITELY isn't acceptable in the military.
Military codes and qualities are Honor,Discipline,Duty. TOLERANCE IS NOT ONE OF THEM!!!
Are they spoiled children or are they Professional Military Personnel under contractual obligation to do what they're ordered to do!!??!!

Have everyone in there plank position, and have him explain his self, if you can't get no where get out there ruck sacks and ready a road March

Is there a opportunity to explain insubordination in combat when the heat is on ! No! Train as you fight! I ain't trying to write no counseling while the mortar rounds coming in
