Can a corporal in a team leader position have me do corrective action (“smoke” me)? And was I wrong to tell him to eat a bag of dicks?

There is a respectful way to let him know he is wrong. Being disrespectful is not the way.

Actually, yes. Because He is an NCO. Nevertheless, all new NCO"s should learn more about Their soldiers who is under the leadership.

Regardless of rank and his inept perception of his newly appointed duties being a service member requires one to have discipline enough to corral their immediate thoughts. Or otherwise don’t let your mouth write a check you can’t cash.
Having been an NCO I would of first pulled you aside and verbally reprimanded you. If the verbal abuse then continued, then I guess we would of walked it up the ladder. We all know in the military when a soldier is given a promotion it will be their opportunity to show their newly given responsibility to their subordinates.

In a word, yes. You are fortunate he did not write you up and get an Article 15 going.

Long before my time, there were SPC5 thru SPC9. Even then an NCO out ranked them all. Yes, even a lowly CORPORAL.

This guy is clearly trying to pull everyone's leg! Don't fall for this ridiculous post!

Wrong is wrong and two wrong makes no one right. There is a chain of command and it dictates have business is done in the military. It doesn't say anything about who came first, who knows the most about the position or even who will be the last man standing in that position when all the chips fall. It's about rank and respect. Plain and simple and all wrapped up in a nutshell. You know you owe him a very humble (please don't take my rank and kick me out) apology. If the military is where you want to be, you most definitely need to know your place, know your rank and follow the chain of command. Teach instead of being disrespectful and you will go far.

When I was in, we were taught to follow your last order, then bring to someone's attention. Also, as a young corporal, I was taught, that sometimes you have to do that, to make the separation to a leadership position. Maybe under the context, it was wrong, but respect the rank, if you don't respect the man.

YOU ARE DEAD WRONG. You should feel very lucky that you were not one of my soldiers. I would have had a strip taken from you if the UCMJ allowed it.

As a SPC you should just know Better, an NCO is an NCO even if he is new to the position. What would you have done if you had the 2 Chevrons and a SPC told you to eat a bag of Dicks? There are always better ways to deal with situations, if you plan on being promoted and taking a leadership position you need to think about that, even still as a SPC you still need to lead by example for the privates in your team, squad platoon and HELL all the privates in the whole unit that may see or hear you, don't let them believe that shit is ok. I became a team leader as a PFC and for about a month or 2 had to be acting squad leader in weapons squad as a 240 gunner, then was promoted to SPC after we got a squad leader, While I held that position even as a PFC my squad respected me as if I was an NCO, and that is the way it should be especially in any infantry unit
