SSG Brown,
In my mind, the "smoke session" has never really gotten the job done. A good leader doesn't need the power to cause their subordinates physical pain to get their point across. MG Schofield said it better than I can.
“The discipline which makes the soldiers of a free country reliable in battle is not to be gained by harsh or tyrannical treatment. On the contrary, such treatment is far more likely to destroy than to make an army. It is possible to impart instruction and to give commands in such a manner and such a tone of voice to inspire in the soldier no feeling but an intense desire to obey, while the opposite manner and tone of voice cannot fail to excite strong resentment and a desire to disobey. The one mode or the other of dealing with subordinates springs from a corresponding spirit in the breast of the commander. He who feels the respect which is due to others cannot fail to inspire in them regard for himself, while he who feels, and hence manifests, disrespect toward others, especially his inferiors, cannot fail to inspire hatred against himself.”

The smoke session is still an available tool in the NCOs kitbag. We must watch how we use it. Like many other things that tool will only work sometimes on some Soldiers. It is not a one tool fix all.
20 years ago the majority of my NCOs didn't care if I had a financial issue or family's problem. They focused on my fault and either smoked me or encouraged me by yelling at me. Today we are taught to identify the underlying problem and fix that.
I honestly believe you are a better leader if you talk to your Soldiers instead of smoking them, but understand that a smoke session can have a great impact if used properly and at the right moment.
I also think a lot of this has come around because of society. I got smacked as a kid and my butt would be black and blue for any mistakes I made. I can honestly say that does not work on my kids. I can get through to my kids more effectively by talking and giving them a verbal dress down. Times change and we must change with them.
Find out how to get through to your Soldiers and then use the right tool for the job. If a good ole fashioned smoke session is in order do it correctly and don't abuse it. I think you will find that just talking to the Soldier will yield better results. Like I always tell my NCOs - you have to be approachable to be an effective leader.
