Which FM is associated with leadership in the Army?

The correct choice is associated with leadership in the Army because FM 6-22, also known as "Army Leadership," is specifically designed to address the concepts, principles, and responsibilities of leadership within the Army. This field manual focuses on how leaders can effectively motivate and guide their subordinates, develop strong teams, and uphold the Army’s core values and ethics. It provides a framework for understanding the attributes and competencies that are essential for effective leadership at all levels within the Army, making it an essential resource for leaders trying to improve their leadership capabilities and enhance unit performance.

In contrast, the other choices pertain to different topics within Army operations and regulations. For example, FM 3-25.26 deals with map reading and land navigation, while FM 350-1 focuses on Army Training and Leader Development. FM 27-10 is centered around the law of land warfare, outlining the legal and ethical considerations in military operations. These documents, while important, do not specifically address leadership principles and practices as FM 6-22 does.
