When I was swotting up for my sift interview, I made notes on the 6 Defence Missions of the RN. As this was what I found on the Navy's website when reading up on the role of the RN. However, I am again swotting up, this time for my AIB, but now on the website, it doesn't have the 8 Defence Missions, but instead 'Defend, Deter and Defeat' Obviously the principles are exactly the same, but if asked something along the lines of 'What is the RN's role?' Can I still refer to the 8DMs? Or am I making mountains out of molehills, and as long as I get across that the Navy aims to provide security for the UK, its citizens and interests, I'll be okay?
