TriviaEdit

• Preston Cole was likely a Lieutenant, Junior Grade when he was aboard the UNSC Las Vegas during the Callisto Incident. Though he is referred to as a "Second Lieutenant," that is not a Navy rank, therefore he was most likely a Lieutenant, Junior Grade, or the Navy equivalent to 2nd Lieutenant, Ensign.
• Jacob Keyes was this rank when he first traveled with Catherine Elizabeth Halsey on the shuttle, Han, to seek out potential SPARTAN-II candidates.
