This Starfleet line rank is inferior to a Lieutenant Commander, and superior to a Lieutenant Junior Grade.
Officers at this rank typically have some command experience, and are occasionally appointed department heads on starships. Typically they are shift commanders in a department under a Lieutenant Commander; for example, a Lieutenant Commander will be chief of engineering and will also be commander of A shift, and there will be a B and a C shift, each under a lieutenant.
Officers at this rank typically have a minimum of 2-5 years of experience, or have completed advanced training in their fields.
