This is a list of naval officer designators in the United States Navy. In the United States Navy, all active and reserve component officers are assigned to one of four officer communities, based on their education, training, and assignments: Line Officers (divided into Unrestricted Line or URL, Restricted Line or RL, and Restricted Line Special Duty or RL SD), Staff Corps Officers, Limited Duty Officers (LDO), or Warrant Officers (WO/CWO). Each community is further subdivided by primary occupation. Each occupation is identified by a designator.
Definition
The officer billet designator codes are four-digit numbers used to identify the primary naval specialty qualifications required of the billet incumbent and to administratively categorize officer billets for proper management and identification. They serve as a manpower management tool when used in conjunction with the officer designator codes. These codes are entered in the Manpower Authorizations (OPNAV Form 1000/2) to indicate the categories of officers required for the billets.
There is no distinction between USN and USNR officers, no matter what the commissioning source. All hold the same ranks, have the same responsibilities and authority, and enjoy the same privileges. As part of the U.S. Navy's Active–Reserve Integration (ARI) initiative that "operationalized" the Navy's Reserve component, the term "U.S. Naval Reserve" was superseded by "U.S. Navy Reserve", and the term USNR was discontinued as a matter of Total Force policy in 2005. All officers in the U.S. Navy now use the term USN with their rank titles.
As used above, Training and Administration of the Reserve (TAR) program officers are reserve officers serving on either fixed or indefinite periods of active duty, while remaining reserve officers, under the authority of 10 USC 12310. The Training and Administration of the Reserve program exists to provide TAR for training, administration, recruiting, organization, and equipping the reserve components.
