Hi Just finished my application for Communications apprentice. Was hoping someone here could give me more information on the communications branch. What different roles are there and what ranks perform these roles? How many communications ratings are usually on board? although I appreciate this may depend on size of ship. I have read that there is a communications officer, are they promotes from within amd what do they do? I have soent lots of time searching and can find general information on what communications do but not specific roles, do they have specific roles or do you cover all possible tasks? Thanks for any information.
