While my unit was training for our deployment to Iraq, we were stationed at Camp Shelby, Miss. While we were there, the rule about females in the male barracks, and so forth, was treated a little loosely.
The general rule was, no one of the opposite sex in barracks after 9pm. If someone of the opposite sex wanted to enter the barracks, they’d have to call “_____, on the floor!”, and wait for an “all clear”.
We had a female SGT who generally didn’t wait for the “all clear” before coming into the barracks, and a few of my roomies complained about it. Nothing was ever done about it, so one of my buddies decided to take matters into his own hands.
