Where can one find the Army definition of leadership?

The Army definition of leadership can be found in ADP 6-22, which stands for Army Doctrine Publication. This publication outlines the Army's leadership philosophy and serves as the foundation for how Army leaders are expected to operate. It provides a comprehensive overview of the principles of leadership within the Army context, addressing the importance of values, ethics, and the responsibility of leaders to inspire and influence others. ADP 6-22 emphasizes that leadership is about people, emphasizing that leaders should be mission-oriented while remaining focused on the needs and development of their subordinates.

Other documents mentioned, such as FM 1-0, AR 600-100, and ATP 6-22.1, each have specific functionalities and focus areas within military operations and personnel management, but ADP 6-22 is the primary source for defining what leadership entails in the Army framework.
