Quite a catch-all sort of offence. Also known as Section 69. If you're going to get your knob out on parade, call The Queen an old cow, piss all over the CO's flower bed, have oral sex with your RAF Police Dog, puke all over the Squadron Mascot and you find that the rest of the Queen's Regulations don't cover your crime then section 69 will. It always does. I know, I was that RAF Police Dog.
