If you have been in similar training circumstances, and enviroments you will understand. Ja sure, making beds does nothing for combat training, but it instill discipline, something which is essential in contact and patrol. The jokes made on troops/trainees are just that, jokes, and those are the things being remembered. And most of the times, trainees/troops get back at their trainer, in a joke. Then obviously opfk will follow, but during time off, they socialize and have a drink together. When it's work, work hard, when it's play time, play hard.
