They won't have a hard time, no trade ever does they'll just go down the list until somebody takes it... not saying it's right or great for experience etc... but it's what happens. Offer it to some young SAC who is keen and he'll take it; because with the career averaged pensions quicker you are up the ranks the better for you. We have a guy getting promoted to WO off one single SJAR so it's not difficult to imagine it happening at any rank if slots really need to be filled.
