Lieutenant is a junior commissioned officer rank in the UNSC Navy, equal in rank to Captain in the UNSC Marine Corps, the UNSC Air Force, and in the UNSC Army.

TitleEdit

This rank is sometimes referred to as "Full Lieutenant" to distinguish it from the subordinate rank of Lieutenant, Junior Grade. Informally, Lieutenants are often addressed as "L.T." or "El Tee"^[1].

While Lieutenant is a rank specific to the UNSC Navy, the title "Lieutenant" is often used to refer to several ranks in the UNSC Defense Force:

Navy

• Lieutenant
• Lieutenant, Junior Grade

Marine Corps, Air Force, and Army

• First Lieutenant
• Second Lieutenant
