Lieutenant

A lieutenant was a rank in a Navy.

Imperial Navy
On a smaller to medium sized vessel, a lieutenant may be a senior officer, possibly the vessel's executive officer. On a larger sized vessel, such as a Star Destroyer, a lieutenant is not high enough to command, but is usually in charge of a section of a vessel's operations. A lieutenant can also be an aid to a senior officer.

A lieutenant is usually still green (compared to field grade officers) but has more experience than a Lieutenant Junior Grade and demonstrates further tactical thinking and leadership.
