I am teaching English to a group of Navy personnel and they have asked me to list their naval ranks and what the English equivalents are.

I have searched the internet and have found only some of the equivalents (mainly for the officers).

Can sonmeone advise me of the equivalents in English of the NON-COMMISSIONED ranks, please?

E.g. oficial de mar, tecnico tercero, segundo & primero, tecnico supervisor segundo & primero

Thank you
