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

Get up in the privates face, with raised voice tell him he's not at home any more and mommy can't protect him anymore, tell him he will do the task and inform him or her that he or she will get the crap details until they learn to respect their superiors.

"You're right. This task odd beneath you. On the other hand, the heads/latrine could use anther cleaning. Supplies are in closet. Get to it."

What the he'll is a senior e-5? Was he smart-mouthin' ya cause you called yourself a senior e-5? Does senior e-5 mean you aren't a junior e-6?

You can’t speak at Parade Rest. If you chose to ignore protocol, I would explained the rank structure in the United States Army and how it pertains to you in this particular situation. At this point, reinforcement training (D&C, Customs & Courtiers) may take up some of this PVT’s spare time. If you still didn’t grasp the concept, forfeiture of pay, extra duties and confined to barracks (as outlined by UCMJ). This is not a fucking Democracy.

Demise the rest of the group. Make them stand there for an hour at attention, go in there and tell him again to do as told. If he refuses again white him up, and give him extra duty. Take away his liberties. And give him more extra duties.

Have them all run. After a brisk 5 mile jog make them go into the showers and have them do mountain climbers. Then explain that it's all about the weakest link in the chain. If one starts to rust the others will soon follow. You'll earn respect, and yes they might hate you but they'll hate the incompetent POS more

P.T. a whole funfest of P.T.

I would make an example out of PFC Fucktard and his team leader, in private, which would immediately alert everyone else to what is going on. I would then proceed to make PFC Soup-Sandwich my personal project for the rest of their assignment.

Smoke that ass!!!!

hmm he blatantly refused, lmao skip the LOC(letter of counseling) n go strait to a LOR(Letter of reprimand)! I had to do that once to another female Airman, She was told to report to me the next day in BDU's and instead showed up in dress blues, said she didn't want that training she preferred to work in an office. lmao. so thought if she was in dress blues we wouldn't make her go out into the field for training, I made her do it in her blues!!!

I believe this is a scenario that most E-5 and above encounter at some point. I would have private shit stain stand fast and clear the room. Then I would give him the opportunity to explain his insubordination. Maybe, just maybe, he has something happening personally that has him out of sorts. If no reasonable explanation is forthcoming I would shove a round of WP up his ass and AR15 him. I believe we need to try to remember the human element without allowing that to undermine our authority.

You have that shitbag and his squad leader stand by after formation, you smoke the dog shit out of both while explaining to the squad leader that his leadership style sucks ass and that he better unfuck the situation! If it happens again its a beat down!

I had a situation like this once in a multi-service school. I was the Student Platoon Sergeant and a newbie Air Force E-2 openly defied my authority. I ordered him to do push-ups and he had the nerve to say that I couldn't make him. Wrong answer. I grabbed him by his hair, kicked his feet out from under him and began pounding his face into the sidewalk until he decided that it would be wise to obey me. Of course, within 2 hours I found myself in front of the Air Force full bird Colonel who ran the school. He attempted to tell me that I couldn't treat Air Force personell like that. I countered with the fact that UCMJ applies to all service branches, and that I was willing to let the entire thing go as a case of successful wall to wall counselling. Otherwise, he would need to start up the Article 15 process for his dumbass airman, if he wished to press the matter further. That was the end of the matter.

Verbal Reprimand Immediately providing him with the alternatives to his continued misbehaviour.

make him stand a attention and drop everyone for push ups forever

I was in the Army from 81-84 and I saw this occur one time....only one time... The platoon was dismissed and dipshit stayed behind. Sgt came strolling by a little later and dipshit was out cold. NEVER happened again....I had no problem with that. I'm from the old school...if we had a problem...we took care of the problem.

Rip his ass out of formation and kick his ass teach him a lesson of respect

Let him know where he stands and who is in charge here .

I suspect it's handled much differently than it would have been dealt with back when I was in...in the 70's that E2 would have had a private training/motivational session with the E-5, behind closed doors

I had two PV2s in my squad who got into a fight in town early one morning. Of course, I got called into the CSM's office at O'dark thirty and got my ass reamed for not training my troops better. Two days later these two decided not to fall out for morning formation on-time. I went into the barracks and found them sleeping in their bunks (both on top bunks directly across from each other). I yelled for them to fall out and they simply rolled over so I grabbed each mattress and proceeded to drag them mattress and all off the rack and onto the floor into a heap. One jumped up and wanted to take a swing but thought better of it. Those two ended up in a very cold place later that day; monitoring a radio relay station on a mountain top for a week with nothing but their authorized clothing, no personal items, shelter halves, water, C-rats and a Soldiers Manual. They finally and reluctantly got their attitudes adjusted but were eventually transferred out of the unit.
