When you have E-8s who are not in compliance with the regulations, is it OK to correct them on their appearance?

I come back from whichever school and tell Top that this certain thing is part of his job now, and he says "OK, I'll check it out"
I come back from whichever school and tell Top that this is no longer your privilidge; now I'm in deep shit!

When I was a young specialist, I would make corrections on anyone. I had Senior NCOs that would actually thank me. But the key is to do it tactfully and outside of everyone else's earshot

Yeah, I don't see anything wrong with it, but caution and tact is important when correcting someone. Privates rarely have the knowledge base to make any corrections like that, but it shouldn't be left to a PVT to make the correction. Hopefully that individuals peers correct his/hers discrepancy first. If done correctly that PVT shows personnel courage by helping a fellow soldier out especially if that soldier is a high rank.

It's not your place. You'll be on fire watch all weekend. If you have enough time to evaluate what someone that far above your pay grade is doing, then you don't have enough to do.

There is plenty of dirt to weed eat, and morning dew on the grass to mop over the weekend.

STOP BEING A MILLENNIAL

I have learned the hard about command retaliation, just leave them alone and let them collect the retirement they are chasing because your career isnt shit to them, they just want your to re-up because higher reenlistment numbers look good on them. If high up is fucked up its because they have stopped giving a fuck.

Totally depends on the person. This is basically Russian Roulette. Even if your lower enlisted of the year most people that outrank you by that much will have a chip on their shoulder. I spent 7 years in the Army/National Guard and I've only seen shit roll down hill. Reading your post I came to 3 possibilities. #1 They have something against you personally. #2 They have your basic power hungry NCO complex. #3 Your jacked up. Not saying there are not more options but these were the first in my mind. But if any of these three are the reason then correcting them will not be pleasant no matter how you go about it.

Lol. You may be a Pvt, but try to think like a General and pick your battles. A sharp Pvt notices things that need corrected. A brave Pvt addresses issues without regard to circumstance. A wise Pvt keeps his noob pie hole shut, makes positive things happen when possible, and doesn't get offended by every little thing he sees.
If you feel you must address the issue, I recommend you use a tone that shows how dissappointed you are with an SNCO who lets a Pvt down. "Why the fuq are your boots so jacked up!!?" is a good start. Do it publicly in front of as many other junior enlisted as possible. That way he will recognize you as a leader among Privates. He will be impressed by your combat ready attitude, and he will react loudly at first to test your courage and resolve. When this happens, show that you command respect by demanding that he apologize and salute you. Most importantly, have someone get video of the confrontation so other privates can learn how it's done. Good luck!

As long as you preface with, "with all due respect" you can say whatever you want! But for real, I never had a problem nonchalantly making a comment, "Chief, your laces are untucked." Of course make sure you're squared away before you comment on someone else... especially to someone that outranks you by quite a bit

If you see an NCO not in correct uniform or wearing a jacked up uniform, yes you can correct them, but remember your military bearing. Don't be a smart ass about it, but be careful and above all make sure you are right before you make the correction.
