This question already has an answer here:
In the process of world-building my space opera's allied navy, I realized I really need to know more about what the functional roles of some of the officers aboard ship are; you know, not just their position's description, but what they actually DO. Sure, I've done a decent amount of research on real-world navies and how they are organized, but I've found very little about what some of the day to day tasks are for these people. Obviously some things a person can fudge, because its a future-era SPACEship after all, not everything works the same, but other things it would be nice to know more about without actually having to join the navy XD Anyone have any experience/knowledge about this stuff? For instance, what is the tactical officer's job when they aren't fighting anybody or running simulations? I'm assuming he/she doesn't just sit around on their butt... And what would your average ensign or midshipman be doing from day to day?
