But what I'm saying is that you move sufficient numbers across from CHF and these become your SMEs initially. Over the passage of time and with sufficient embarkations, the experience breeds across to the RAF and in the future the tradition and skillset is back up to the necessary levels. If the RAF made littoral move one of it's roles then over time they would make it work in the same way that knowledge and experience gets passed on to new personnel through training in every branch of the armed forces.
