Training days 66-69 make up Marine Week; this is the last and final week of Recruit Training.
Marine Week is a period of time where the new Marines learn to operate in a more decentralized environment. After eleven weeks of being told what to do almost every waking moment, this is a chance for them to show their drill instructors what they have learned about small unit leadership, ethics, and core values.
They are not recruits any more, they are allowed to wear a watch, to move about the Depot as small units, and are now addressed by their rank and last name, or simply as “Marine.”
Drill instructors make a transition as well, serving more as mentors, and the new Marines call them by their rank and last name.
There is also an important moment when Marines, past and present, come visit and “Share the Legacy,” passing along their experiences, and telling the new Marines how the Corps’ core values have shaped their lives.
