Correcting Indisciplines in the Senior ranks

I never knew what a "indiscipline" was until one of my First Sergeants told the unit. We need to correct all the indiscipline's in the unit. He explained they are the little regulations we choose not to follow because they have become the norm or don't really hurt anyone or anything. I immediately went to AR 670-1 and printed out several copies where it states..Hands will only be placed in the pockets momentarily to place or retrieve items. (doing that after I attempted to make several corrections on senior enlisted and was shrugged off) I posted these all over the hanger until the first sergeant asked who did it. I told him I had because I had tried to correct the indiscipline's I saw and was ignored. Well he was a violator at the time, but after that I never saw his hands in his pockets again. Should it have came to that or just been handled with a on the spot correction? any way, my point to this is. These indiscipline's we fail to correct are a learned behavior. I feel we as senior NCO's, Officers, and Warrant's should take a hard look at these and correct it. It has ran ramped from hands in the pockets, glasses on the head, the wrong sun glasses, keys hanging off the belt loops, to the many other. And the seniors are the biggest violators. What are your opinions?
