Keep browsing in the Navy forum long enough, and you will stumble across explanations.
Here’s a crash course.
Navy officers go into a specialty area after commissioning, that can be called their warfare community or their designator (each community has a 4-digit designation).
- There are some major groups of these communities.
- Each community will have a career path taking the officer through various assignments and qualifications across the arc of their career. There will be some tours of duty (assignments) all must do in the community, and then some other assignments not everyone does. A good example is a Blue Angels Navy pilot. That pilot has followed a path from initial flight training, alternating shore and sea/operational duty tours. Then there is an opportunity to apply for an Angels slot, or a White House Fellowship or some other assignment.
- Back to communities.
-
Unrestricted line (URL). The term is likely drawn from the Royal Navy back in the day, when “ships of the line” were the major battle platforms, distinguishing them from supply ships and other support ships. The URL communities are surface warfare, submarines, aviation (pilot), aviation (NFO), SEAL, EOD, etc. They are unrestricted because these officers may command in their warfare community as well as ashore. If a SWO, they could command a ship or perhaps a training command ashore. USNA and NROTC are geared to produce officers going to URL communities, usually the most populous. These officers do the primary warfare missions, working closely with other officer communities.
-
Restricted Line (RL). These officers may command in their own community, but not outside it. There is an array of smaller communities whose officers are technical experts in their field: intel, cyber, meteorology, and many others. They may be the only member of their community assigned to a unit, such as an intel officer with a deployed aviation squadron, or they may be at a command dedicated to their specialty area or assigned to a big staff to contribute in their specialty area. These communities are pretty much non-existent opportunities for NROTC and in small handfuls out of USNA. Often URL officers competitively apply for lateral transfer and redesignation into an RL community later on in their career. Some may become NPQ in their URL community and are offered a spot in an RL community.
-
Staff Corps. These are your “professions” - Medical Corps, Nurse Corps, Dental Corps, Medical Service Corps, JAG Corps, Chaplain Corps, Supply Corps, Civil Engineering Corps, etc. They serve in their own community and may command in their community. USNA allows about 15 grads to go Med Corps or Dental Corps each year. NROTC does not have a formal program to apply for a Corps role. Again, you might see a USNA midshipman go into CEC if they had received a color blind waiver to get into USNA, and were allowed to go RL or URL.
- There are other officer communities such as Chief Warrant Officer (CWO) or Limited Duty Officer (LDO). Those are for enlisted later in their careers.
Some links to illustrate:
Every year, USNA publishes where new ensigns are headed, and you can see the majority go URL. You can also see the relative few going RL or Staff Corps.

Each and every Navy officer community has a community manager who oversees the career path. Here’s an example from the MyNavyHR website, where you find detailed descriptions of each family of communities, career paths, how to transfer in, etc. Here’s a typical detailer (assignment counselor) slide deck used for briefings to community members and others. This is for the 1310 (pilot designator) and 1320 (naval flight officer designator) in the VFA (fighter-attack community. Enjoy the call signs. Pay attention to the options for sea shore rotation and the timelines. Where it says USNA or NROTC, that means staff assignment at USNA or a NROTC unit.
There will be an open notes pop quiz later.
