my son is doing his basic at Raleigh and discovered he can't pop his ears. He is gutted having set his heart on being a submariner - he doesn't know what to do for the best now as he is unsure that he want to be in the branch he chose on the surface, any advice welcome.It seems he will be sent on the submariner training anyway and wont be re tested untill a few weeks into that - if he then fails the navy will allocate a different trade, would he be better trying to change now it doesn't seem clear whether thats an option or not.
