PontiusNavigator,
Your USAF Air Police friend was well qualified to fit in with the 'Rocks' and their war like scenarios, whereas he would have been completely out of his depth big time in the RAFP, where the specialists are on a par with the USAF OSI, as the following link will show you. I and many, many, colleages have considerable 'shared experiences' with OSI, in UK and across NATO, much of it very enjoyable.
