Woe to the person who accidentally punched in the wrong pin number more than twice in a row. You would all of a sudden have four or five young Air Force security police officers pointing weapons at you, and you would be commanded to put your hands in the air and not move. In some instances, they would make you get face down on the ground (eating dirt), or up against a chain link fence. This procedure was fondly known as getting "jacked up", and yes, it happened to me once.
We used to get quite a hoot out of it when it would happen to one of the more obnoxious department honchos, because the entire complex would go on lockdown, and you could see the hapless "jackee" on the security monitors all over the place.
While in Basic Training, at Fort Leonard Wood, Missouri, we were on our first bivouwac. The Deputy Commander of the Post had just come from the O Club, and decided to check on his troops. When he was told to advance and be recognized, the guard didn't have the slightest idea who he was, and he had no ID on his person. He sputtered for a while, and the guard said, 'Well, General or Catpain or Sergeant, you're going to go for a walk with me.' The guard had just changed, and the good general walked ahead of the private for nearly two hours.
Our CO recognized the troop at an assembly the next day, and told us he had held a US Army type general at gunpoint for two hours the night before.
