As a transferee to the AMS I was surprised to find that it is common practise for Officers (and SNCOs) to fall in in the Ranks and be marched about by NCOs. I have pointed out that this is not really the done thing - for any number of reasons, but have been told to either come up with a regulation that says they should not, or wind my neck in. The only reference that I can find is in the Regs about officers wearing uniform when not on duty. It mentions that Remeberance Parades are suitable occations to wear uniform, but an officer in uniform must not march in the ranks on such occations. Can anybody come up with a quotable authority for why Officers should not 'fall in' in the ranks?
