What characterizes a Marine devoted to leading 24/7 according to the Horizontal Themes?

A Marine devoted to leading 24/7 embodies the principle of operational readiness at all times. This means that leadership is not confined to designated hours or formal events; instead, it reflects a continuous commitment to being prepared and responsive in any situation. This characteristic illustrates the idea that true leadership involves being proactive, ensuring that one is always capable of leading, mentoring, and influencing others, regardless of time or circumstance.

In contrast, the other options do not encapsulate the essence of 24/7 leadership. Conducting training twice a month may indicate a structured approach to development, but it does not convey the ongoing readiness expected of a Marine leader. Participation in community service events, while valuable for building relationships and representing the Marine Corps positively, also doesn't reflect a consistent leadership commitment throughout all hours. Leading only during official hours inherently contradicts the concept of continuous leadership, as it limits a Marine’s influence and availability to their peers and subordinates outside of those times. Therefore, operational readiness at all times best characterizes a Marine devoted to leading 24/7.
