Navy Legalman LN
The Navy details the path to the Legalman (LN) rating, a role that is not open to direct enlistment for non-prior service applicants. Eligibility requires under 10 years of service, at least 24 months in the current rating, and being within 12 months of the projected rotation date.
Those selected attend the Legalman class “A” school, roughly 11 weeks long, at the Naval Justice School in Newport, Rhode Island. The rating carries a four-year enlistment obligation.
