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

In my day the 60's take him out back of the barracks and have a serious conversation about the head and shoulders with my fists, however that is not acceptable any longer

Re-affirm and direct, where did an E-2 get the idea that they had an opinion? If there is an issue with an order subordinates must understand the protocols for dealing with it. It's open defiance, the E-2 has already earned the Article 15 they can debate the lawfulness of the order with command. If upon redirection the E-2 continues to refuse they are removed from the formation (publicly) and held by the MA until I've finished with my routines...Then we'll discuss bearing and protocol.

Dog 'em out. Tell him who I am and what he is supposed to be, while he is doing push-ups from here to eternity or at least until i get tired. He gets all the shit detail all week.

I would light his ass up so that the rest of the division didn't think I was a push over and I would give him every single miserable crap job that no one wants to do until he requested TAD orders out of my division. I would have that dude cleaning bilges, scrubbing deck plates, mandatory berthing head cleaning three times a day, not to mention a report chit and a trip to the chief's mess. This is the military, if you singed up to be a problem you will be dealt with accordingly. Luckily for the rest of us who joined the military for the right reasons, the people like the guy in this example usually end up getting themselves either kicked out, or restricted to the point where they no longer hinder the rest of the division.

Simply inform smart ass that what you have told them should be considered a lawful order. If they keep up the smart ass routine, and refuse to do the work, Article 15 for failing to obey a lawful order and insubordination.

If it continues, process ass-eyes for a discharge.

As it's an Order, the E2 must explain why it can't preform the Order..usually, from the front leaning rest position....

would never happen telling a sgt your not gonna do it or give it to someone else.

If i was the E5 I would drop everyone pt them for an hour still give private orders let the other disipline the pvt on there own time

Time for some combatives training

Drop the entire company except the Big mouth e2 mash them and then let them sort shit out
