When an E-4 calls me "hey" or "hey man" knowing that I am an officer, should I bother to correct him?

Yep, immediately and professionally. And then just as importantly have a quiet talk with their senior NCO; obviously individual needs some counseling by the enlisted leaders.

Absolutely make that on the spot correction immediately. Chances are that his NCOs are too lax in their discipline and most likely allow their soldiers to get too comfortable. While recruiting is hard and maintaining manpower is getting more difficult I would rather have a smaller well discerned unit than a large well manned undisciplined one.

We never had this problem in the Marines...even Junior NCO's are adressed by their "Entire Rank Title" and greeted with respect. An officer??? Shieet, that is the problem with Marine 2nd Lt. 's. They know their rank is Godlike and yet they don't know anything...

You definetly need to corrects this SPC. If you don't, all military courtesy is lost,

Are you sure you’re an officer? You absolutely should correct him. ASAP!

I think that you have to respect the officer's rank but not address him as hey or hey man.

Damn right you correct his butt. Stand him at attention and require him to address you according to your rank, with a Sir; Officer last name, then put him on report with his commanding officer or if in your unit, with fifty pushups and extra duties until he learns the correct way to address officers. He is not an officer's buddy, or wasnt when I was commissioned, but in todays military who knows what is custom; duty; regulation. No "red" cards in this issue.

Um. . . Yes. If you don't, you perpetuate a culture of substandard discipline and a lack of respect for your position.

When not in uniform, it still needs to be semi-professional, because he's treating you like he'd treat any other E4 he'd see out in town. Whenever I came across officers in town that I recognized, they were still greeted with a Sir or Ma'am. Didn't matter if they were a butter bar & I was the salty E6 closing on my retirement, they received the same level of respect.

If you don't correct him, or her, you don't deserve to be an officer.
