A friend of mine spent some time in charge of the motor pool at an army post in Germany. The general procedure at the time was to bring a vehicle in when it became unusable and put it back on the road when it was working. The book said they should bring a vehicle in when anything was wrong with it and not put it back in service until it was in perfect condition. They got a new commanding officer who had spent his entire military career in the Pentagon. He decided that they would run things by the book. My friend obeyed and had the whole base shut down in a week by having no legally running vehicles.
