The USS Crommelin, like many US Navy ships, are sectioned and managed through various departments. This allows for efficient team-building, as well as maintaining its focus on the ship's overall objectives. Access to the list of DEPARTMENTS can be found on the navigation column to the right of this page.

Navy Ranks and Rates

BM1The US Navy rating structure is confusing to most people outside the organization. Two similar sounding terms are used to describe Navy enlisted status - rate and rating. The term rank used among enlisted sailors is incorrect. Instead, it is their rate that equates to military paygrade, while rating is one's occupational specialty. The image to the right identifies the enlisted sailor as a petty officer first class (PO1), which is their rate. The marking located between the crow and the chevrons indicates the individual's occupation. In this image, Boatswain (pronounced bo' sun) Mate is their rating. Used in combination, Boatswain Mate First Class (BM1), defines both the rate, petty officer first class (E-6), and rating Boatswain Mate.

Navy Officers wear their rank devices in different places on their uniforms, depending upon the uniform. The three basic uniforms and the type of rank devices are: khakis (a working uniform) - pins on the collar; whites - stripes on the shoulder boards; and, blues - stripes sewn on the lower sleeve. Shoulder boards are also worn on bridge coats and reefers.

Officers in the Navy are either Line Officers or Staff Corps. Among these are also Limited Duty Officers and Commissioned Warrant Officers. Staff Corps and Commission Warrant Officers wear insignia in place of the Line Officer's star.
