What MOS/rating (marines or navy)would this be?

So when ever I see a movie, either in one a ship or on land, I see people sitting in a really dark room with big computer screens with maps and fast scrolling text on them, they all are talking into headsets to different commands (imagine the opening scene where that admiral is in that room with the videos of the village). I know it has to do something in intel. but what MOS is this, also what Rating in the Navy would closely resemble this. I know it all COD, and I know that I seem ingorant but remember I am not in the miltary, so please keep your answer respectful. thanks
