Which term refers to the adherence to moral and ethical principles?

The term that refers to the adherence to moral and ethical principles is integrity. Integrity embodies the concepts of honesty and strong moral values, suggesting that an individual acts in accordance with their beliefs and principles, even when faced with challenges or temptations to do otherwise. It reflects a consistency of actions, values, methods, measures, and principles, showcasing a person's commitment to doing what is right.

In the context of leadership and the Marine Corps, integrity is foundational as it builds trust among team members and fosters a culture where ethical decision-making is prioritized. This adherence to values not only develops personal character but also enhances unit cohesion and effectiveness. While compliance, discipline, and respect are all important aspects of military conduct and culture, they do not specifically capture the essence of moral and ethical adherence in the same way that integrity does.
