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?

We just got a new Corporal who recently reclassed to mortars. He’s highly motivated (hooah), and during a training event, we had a disagreement over how to perform large deflections. He told me to "drop," but the fire mission he was calling would’ve put us outside the safety fan during a live fire and could have potentially caused injuries to other elements participating in the exercise.

Now, I understand and respect his rank, but I’ve been a mortarman longer and currently serve as the Gun 2 gunner. The fact is—he was wrong. He just became an 11C, and when he wouldn’t listen to correction or reason, I told him (admittedly out of frustration) to eat a bag of d***s.

I’m curious to hear what others think—especially when it comes to situations where rank clashes with experience and safety is on the line.
