I am applying to become a WS on the surface fleet coinciding with an application to become a Warfare Officer (Due to uncertainty of future eligibility for officer application to proceed). My query, that I hope someone can help with is; I have been granted clearance for WS however have been told by AFCO I will need to obtain clearance again for Warfare Officer. Does this mean the clearance level for officer is higher/harder to get than for a rating? Or is it simply due to the fact it is a separate application and therefore kept separate in all aspects? I did ask a careers adviser this on the phone however it was one of those conversations that didn't provide much clarity and I don't wish to phone up again asking the same question. After searching the old threads I'm hoping this isn't another repeated question regarding security clearances as I failed to find it. Many thanks.
