Should the Army bring back "old school" leadership?

I know that this topic has been discussed numerous times and as long as I have been in (Since 2004) the Army has gotten soft on it's discipline. For instance, when I first arrived to this unit and I was in processing, a PFC was joking around with me like I was his best friend.  And the first thought to cross my mind was "this soldier lacks discipline."  Coming from Fort Hood, which is a very disciplined post and coming to Fort Leavenworth, the transition was very hard for me - I can't be that "relaxed" NCO that everyone wants me to be. Soldiers and officers walking around with their hands in their pockets, smoking and walking, and amongst other things that make me want to be that "**shole" NCO.  I miss the soldiers standing at parade rest for NCOs and I miss seeing the E-6s standing at parade rest for the E-7s.  At my last unit, if there were two E-6s and one went to SLC and the other one didnt, the one that didn't stood at parade rest for the other one. If I come across another E-5 that has been to ALC (because I haven't) - I'm going to stand at parade rest for that other E-5.  You can all see where I am going with this.. Input would be greatly appreciated. Thank you..
