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

Me: Front leaning rest position, move, E2 Shit-for-brains does not want to follow his order. You will do pushups till I get tired of counting! I can count for a long time, with out tiring. Four count push up position move, one two three four, one, one two three four, two....! Platoon leader, you and the rest of the platoon will need to explain to E2 Shit-for-brains why he will follow orders without hesitation and without question, is that clear? One two three four, twenty,...! If not, they have a fine place to rest at Ft. Leavenworth for E2 Shit-for-brains to fulfill his obligation to Uncle Sam!

Put him in a push up position and tell him to stay there till I was done lol

Smoke the whole squad. Twice. If one person messes up, you all mess up. The military is not a place for an "Individual". Everything that you do will take some sort of team effort, and that starts from the moment you step off the bus and meet your battle buddy. Point blank, if you are lower ranking then someone, you have no reason to open your mouth unless it's to say "Yes sir", "No sir", or to be kissing ass. I'm not myself in the military, only a JROTC cadet, but even in my school my Colonel and Master Sargent believe in and practice the same. This isn't high school anymore, no one cares about your feelings. You made a decision to be there, so deal with your own problems on your own time.

Hand him or her the Sunday employment ads, inform them the military is not for them and then smash them in the face with a fucking boot. Oh, wait, this is a kinder, gentler, lamer military... uhhhh then escort them to the commander and begin the process of administrative discharge.

Decide they would rather do PT all day and assign them that.

I was a seasoned E4 Specialist, numerous Bradley Gunnerys, Border Tours at OP Alpha and time with Recce Troop Blues and Royals Squadron Her Majesty's Royal Army.... on a early Sat morning aN NCO came into my barracks room woke us up and told us to "look alive, our Country needs you"... i responded "aww come on Sarge its a big Country, cant you find someone else......" not only did he not think my joke was funny he lit me up..... so a shitbird E2 with no time in nothing needs to be severely disciplined!!! especially since he had the balls and disrespect to do it in formation......

Release all except him and take him to the sawdust pit for corrective action. After 15 minutes, it will correct the problem fast.

Let my pen do the talking....

That's fine son. We'll move that down to your second assignment. Keep it in your pocket. After I dismiss these fine men, your first assignment will be to report with me to the first Sargent to be reassigned. You're outa here.
Turn and ask, anyone else have a problem?

If you are a senior E5 Marine and you don't know what to do...perhaps you should switch jobs with the Grunt
