What do you do when a soldier refuses to listen to your directions?

It is funny, if they want to wear that why be in the military, might as well be a civilian. Don't they know what the oath is, you are suppose to obey people that are your commanders, DI, officer etc. They are disobeying a direct order, i looked it up on a goggle search it is an Article 92 in the UCMJ.

In the sunglass example. Ask if he has a med.pass for the glasses in not why he chose to wear them in formation. Then ask if he thought he was better then the rest why he didn't want too be part of a unit. AND give the formation extra PT but not him. If he refuses To remove them. All this is told in front of the formation. Your reasoning is he is exempt and doesn't have to have extra PT. Then let him know if it happens again he gets an article 15. Or just give the article 15 after repeated orders too take the off. your call.

spank him

There are regulation for wearing sunglasses with a uniform for each branch. As a NCO if you put you hands on the person this big trouble for your self What need to be done is if the person does not follow instructions they do have a name tag on there uniform, find there command that address the issue that way I guarantee once there comand finds out about this it will be address right away

I've been out for a while, but can't you just drop him until his desire to challenge you goes away? My humble suggestion is to tell that fucker to meet you after closing formation with 2 full canteens and have him do sprints and then chug the entire bottle and repeat for a while. That may fix his hearing.

Assuming you've done your homework to find out if there is something seriously wrong with the Soldier (depression, maritial issues, etc) that needs to be addressed, and since you can't physically hurt Soldiers anymore, you have to hit them the only two other places it hurts more...their time and money. If that doesn't work, kick them out right? Wrong. Everyone can be useful in the military, even if they only serve as an example of what happens when you don't so the right thing. By all means, make their process out of the military as long and excruciating as possible. It's the least they can do on their way out.

I would remove the sunglasses for him, then mangle them in front of the squad or whoever is present. I would use it as an example of what happens when and order is disobeyed. If he or she wants to repeat it then go for insubordination.

I would take his sunglasses off for him and mangle them in front of the squad or whoever is present so that it will serve as an example for the others. If he repeats it then go for insubordination.

Doesn’t this simply fall under failure to obey a lawful order? Forgive me for not knowing the regulation but I know that’s a thing.

In my professional opinion as a former Non-Commission Officer of the United States Marine Corps, it wouldn’t have happened, especially in formation. In over 21 years in the Marine Corps I have never had a problem with any of my Marines in formation. Per say, whatever a leader does or doesn’t do will definitely reflect the character relationship of his people. Discipline is a must and cannot be overlooked by a simple infraction.
