I had a drill sergeant roll with me on fire watch duty, one time in basic. I had trained under a Renzo Gracie brown belt for a while before joining and I smoked him. The agreement was, if I win and don’t tell anyone there would be no consequences. We both kept our word. I mean, I’m telling you now, but that doesn’t count. He just didn’t want to risk having to deal with any disrespect from other privates.
