According to the Marine Corps Manual, an individual's responsibility for leadership is:

The emphasis on leadership being not dependent on authority highlights the Marine Corps' belief that effective leadership stems from personal qualities and actions rather than merely one's rank or official position. This perspective is critical in fostering a culture where everyone, regardless of their job title or grade, takes on leadership roles and responsibilities.

In the Marine Corps, true leadership is demonstrated through influence, integrity, and the ability to motivate others, which can be exhibited by individuals at any rank. This principle encourages Marines to step up and lead regardless of their authority, instilling a sense of ownership and accountability among all members of the team. Leadership is viewed as a shared responsibility, which enhances teamwork and unit cohesion, essential factors for maritime effectiveness and success in operations.

While rank, experience, and seniority can certainly play a role in a person's leadership style and approach, the fundamental idea is that anyone can lead and inspire others based on their character and actions, reinforcing the notion that leadership is more about actions and influence than title.
