Marine Corps punishes drill instructors and officers after hazing incidents
The cases, which have not previously been disclosed to the public, occurred in the 4th Recruit Training Battalion, a unit in which female drill instructors train female recruits. The investigations were opened as the service began considering more fully integrating male and female recruits during training, as in the other services.
The senior drill instructor later found the recruit on a bathroom bench at night writing to a former Reserve Officer Training Corps instructor, a sergeant major, about the incident. The recruit told an investigating officer the instructor confiscated several letters and asked other recruits the next day whether they would say she had abused them.

...to begin with, adequate physical exercise will insure that no one will be up in the middle of the night writing "snitch letters". Back in 1963 if the drill instructor caught ya anywhere but in your rack doing anything besides sleeping they would wake everybody in the barracks up exercise em for an hour, tell em who got them in trouble and then turn the lights out. Repeat offenders were not common.

Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
