In Hawaii, shortly after a change of command we had a new order drafted, signed off on by JAG, and the commander had the 1SG read it aloud to the company at the end of day formation on a Thursday before a long weekend. They then distributed copies to every Soldier to post in their rooms on the back of the door. They also told everyone that they would be checking on this in the very near future and not to take this warning lightly. The 1SG even did the left foot stomp three times and hinted that Tuesday would be an early morning for the company (even though there was nothing on the training schedule that morning).
At the end of the long weekend, we had a health and welfare. We caught no less then six Soldiers sharing rooms/beds with others. Some were NCO-Junior Enlisted.
Now, I'll agree with you that people will do what people do and issuing orders like this are often counter-productive to their intent. But, in this case, I lay all blame on the Soldiers that were caught, honestly. The commander ordered the health and welfare hoping people would be smart and take the warning, at least for that weekend, and then she'd let sleeping dogs (haha) lie. She figured she'd probably catch one pair of idiots at the most, but not six pairs.
If you take an obvious warning and piss on it, you deserve what you get.
On a side note, this little episode did let the company know that there was a new sheriff in town and not to take her lightly. She did turn out to be a good commander and officer, if a little opinionated on the "not in my barracks" policy.
That reminds me of 1SG Kalbrenner - "What are you going to do this weekend Alpha Company?"
Entire company in gleeful amusement - "Wrap that rascal, 1SG!"
1SG - "Not in my barracks!"
