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

Smoke their assets for the reminder of the day!

I'd pull him aside and explain to him that he was going to do exactly what I asked him to or I'd write him up for disobeying a direct order and then I'd have doing a bunch of s*** That he hated just to let him know who his boss is !

Throat punch

I'd probably start yelling things like "who the hell do you think you are?" And let them know real fast to get out of my face and do as they were told or there'd be hell to pay.

"Do you want to be a Marine"? If Yes, then "marines are humble and respectful, do you want to show your brothers that you are serious about keeping their lives safe?" If yes (and it should be) then "well then act like a Marine and cut the shit"

This is the whole reason I left the military.I and another NCO were in the armory talking while a few privates and specialist were cleaning weapons.A female SPC walks in and yells "Ok everyone shut the F up".I told her "there are NCO's in this room and there are more respectful ways to be heard".My platoon sgt (E-6) called me into his office and told me I needed to respect that E-4 and didn't need to say anything to her in front of people.Two weeks later when time to reenlist came up,I didn't.If I had done what she did when I was a pvt or spc I wouldn't have walked out of the armory.

Outside mister!!

Smack the the taste out of his mouth.

That has happened and after everyone else departed, the E2 and I left for a dark space outside of the hangar. No more problems!!

I guess kicking them in the nuts is no longer acceptable?

Straight Wack to put back in Track.

Never had a PFC that stupid..........

rigorous physical training

I would surely make an example of this Boot Marines conduct, and it would not go unpunished, VI's disobeying a lawful order charges, or platoon discipline via extra duty, and all the other shit can job I could find. These job would make the one he refuse to do so impossible, he would request transfer to another unit.

Take him and his squad leader into office. Restate the order. An explanation as to why it needs done (mellenials need that) shouldn't be given as order must be maintained and enforcement if not followed without question. If he still is defiant Ar15 and maybe even unsay him out.

We would have words later. It wouldn't be a good thing to have animosity within the ranks. If that didn't work I would let my squad leader deal with him.

Ensure that bitch gets the GI virus and take him for a 6 mile run

A disciplinary action is in order. The E2 is blatantly refusing an order. 20 push-ups or sit-ups is a reasonable disciplinary action. But perhaps not harsh enough. I just took the time to read 3 responses. As for myself, I scored a 97 on the ASVAB, but couldn't pass the Physical due to nerve damage. The responses I read were right on the money, and in my opinion, a better option than potentially crushing an E2's throat. My father came out of Officer's Basic and was stationed at Ft Carson as a Drill Sargent. During gas mask training, a fresh recruit refused to put on his gas mask. My father took the steps of his training to encourage the recruit to follow through with the orders. No good. My father broke down and cussed and swore at the recruit at high volume. The stupid kid still refused to follow orders. To my knowledge, striking a subordinate was not an option. He got himself transferred into the Army and earned his wings flying helicopters

Beat his ass

Give them some good old military structure. Up in the face tell him to get down on his face. Respect. Who does this E2 think he is lol
