Common Courtesy?

I would say general military authority applies here....on the spot corrections with reenforcing corrective training can be administered by anyone senior to another individual. The only acception would be if the on the sport corrective training interfers with something the individual's first line supervisor has this doing (e.g. mission accomplishment). Other wise, you are correct.

I would also go further to ask, did you pull the two NCOs aside and discuss being professional in a building where others can see them arguing? The first line of the NCO creed comes to mind....

SFC Butler,

I will say this; Two NCO's shouldn't be arguing out like this. They should have done this behind closed doors. It's considered unprofessional and shouldn't be done in front of Soldiers. For the case of corrective training, if it was me and this Soldier disrespected me or did something out of regulations or context, I would make that Soldier stand at parade rest and correct him on his deficiencies. Then I would get his first line and inform him of the situation and let him handle it. If his first line or no one was around in his chain of command, then I would handle the situation with corrective training and inform his first line immediately when I saw him.

If it was something very serious, I would call him immediately. Now if this NCO wants to get in a yelling match with me because he felt my standards are not up to part with his, then I would bring this matter up to my Platoon Sergeant. Speaking from experience as I've had this happen to me with another NCO correcting one of my Soldiers and me corrective another NCO's Soldier, I've never had a yelling match about standards nor minded if another NCO corrected my Soldier. As long as the corrective training is in direct relations with what that Soldier did then I believe that NCO is in the right. 

I feel that "our" Army has taken a turn for a more undisciplined force. NCO's power has been stripped and we are not supported by our senior NCOs. Don't get me wrong, we still have a few out there that are still instilled with the "old school ways", but not many. Gosh forbid if you raise your voice to a soldier, or force a soldier to do extra physical training. What happened to NCO's being respected and NCO's actually earning their rank and not just have it handed to them? Why is it so hard to get good quality NCO's who all share the same beliefs and values? If a Soldier, no matter the rank, is wrong then he or she should be corrected without it being wrong. As a courtesy, inform the CoC then carry on. If our NCO's were doing their job the right way, their Soldier's will have discipline and accept the corrections then move out.
