Which of the following is NOT one of the three pillars of leader development?

The three pillars of leader development typically include operational assignments, self-development, and institutional training. Operational assignments provide real-world experiences where leaders can practice their skills and apply their knowledge in dynamic environments. Self-development encourages individuals to take responsibility for their own learning and growth outside of formal structures, fostering continuous improvement and adaptability. Institutional training consists of formal education and training programs provided by military institutions that aim to develop the competencies necessary for effective leadership.

Team building, while an important activity that enhances unit cohesion and operational effectiveness, is not classified as one of the primary pillars of leader development. Instead, it often falls under the broader applications of leadership skills developed through the other three pillars. Thus, recognizing that team building is not formally designated as a pillar is why that option stands out in this context.
