X Division It is in the hands of X division, under the control of the executive officer, that a great deal of the ship's business rests.  In the ship's office, the yeomen handle the brunt of the paperwork gen- erated by the various departments on the ship, the personnelmen handle the entire job of service records and personnel transfers and orders, and together they share the tasks of compliling everything from seralized letters from the command to daily printing of the plan of the day.  Late hours, long days hovered over the typewriter, and much time spent in delving for the correct way to do things in a number of manuals - this is their job. In addition to running the ship's office, x division also includes the medical department ( composed of the hospital corpsmen), and the chief master-at arms (responsible for the ship's own police force).X division is essential to the operation of the ship.
