I'm an E-6 SH, I currently have a TS but that's just due to my Rate (You Army folks call that an MOS) and some of my Collateral Duties. I'm an Operations Specialist, and deal with Part Intel, Part Operations, Part Communications.

Everyone on board a Navy Ship requires at least Confidential Clearance. When the ship is currently underway, its position is Classified.
