Could anyone tell me what promotion opportunities are like serving in the Submarine Service? Only from a ratings point of view that is. My 1st choice branch is Warfare Specialist, and any specific information on that branches promotion opportunities would be great. What could I expect in 10 years time? Is retiring after 22 years as a WO1 or 2 a real possibility? Also is junior rate promotion based on experience? Or do you actually have to prove merit to gain advancement? Thanks to anyone answering my annoying questions.
