Ensign Rank Insignia
The most junior Starfleet line rank and is immediately inferior to Lieutenant Junior Grade.
It is the rank bestowed on newly-commissioned officers when they graduate from Starfleet Academy. Ensigns typically begin their careers as the most junior officers in the department of their chosen specialty. Ensigns who have strongly distinguished themselves in their academy class or on duty may sometimes be given posts as main-shift bridge officers (for example Ensign Harry Kim).
