Sergeant Sparkson is the third shift (0000-0800) Signal Intelligence Operator (SIO) aboard the Sabrosa. As third shift SIO on a training boat, Sparkson spends most of his time looking busy, trying to look busy, taking extended bathroom breaks or doing crossword puzzles. He's lucky if he logs more than sixty hours of Real Work during a cruise. It's a boring, boring job, but hey- SigInt is a pay grade above SigComms, dammit. And despite the tedium, it looks great on a resume.
