Though regulations state no hands in your pockets in uniform, what are your thoughts on those who hold their belt buckle or waistline?

Either way I never saw any problems with it. However, if your hands are in your pockets you can’t be productive. But the rules are the rules.

At times it should be ok, but rare

Negative

It's called "discipline", something this younger generation has no concept of...

Hands in pockets does look slouchy in Garrison, but when you are in the field and it is freezing cold, it shoulden't matter. Eisenhower and Bradley both often were foto'd with hands in pockets. About the only one who wasn't was Patton.

I had a CSM once tell me the Army issues you gloves if your hands are cold use them...good times

What about belt loops?

Chesty can do whatever he wants.

Technically you shouldn’t do it because it can be considered framing which I don’t care for really but there are some sharp shooters out there that’ll make it a big deal and the soldier in question may get I trouble for something so small

A lot of silly rules the army has is not for pissing soldiers off, it is done for discipline, if you don't have the discipline to do something as minor as keep your hands out of your pockets then you won't have the discipline to follow the big rules that does matter, then again I am old school military.
