Sorry if I'm cluttering up the wrong forum, but I have a hypothetical question, if I may... From what I understand, the minimum age to join the officer ranks of the Royal Navy is 17. Let's say there's some genius who has earned their master's degree (or even a PhD) in nuclear engineering by age 16. For reasons unknown, this brainiac prodigy wants to join the service and become a submariner rather than work in a civilian laboratory. Given his higher degree, would he skip some/any of the lower ranks upon signing up, or would he still start as a midshipman? If he did start as a midshipman, would he advance any faster in rank than normal? For instance, would it be possible for him to reach the rank of full Lieutenant before age 21? Any insight would be much appreciated. Thank you!
