Which leadership principle helps Marines perform better, take ownership, and demonstrate high levels of morale?

• A. Lead by example
• B. Train until perfect
• C. Communicate frequently
• D. Keep your Marine informed

Answer: (D)

Leading by example is the most influential way a leader shapes a unit. When a leader models the standards, work ethic, and commitment they expect, Marines are more likely to perform to those standards, take ownership of their responsibilities, and stay motivated, which in turn boosts morale. This visible consistency between what is preached and what is practiced builds trust and shows that the leader earns the right to lead, encouraging others to embody the same behaviors. While clear communication and keeping Marines informed support performance, they work best when tied to a leader’s demonstrated actions, making leading by example the strongest driver of better performance, ownership, and morale.
