As the keystone leadership manual for the United States Army, FM 6-22 establishes leadership doctrine, the fundamental principles by which Army leaders act to accomplish their mission and care for their people.FM 6-22 applies to officers, warrant officers, noncommissioned officers, and enlisted Soldiers of all Army components, and to Army civilians. From Soldiers in basic training to newly commissioned officers, new leaders learn how to lead with this manual as a basis. FM 6-22 is prepared under the direction of the Army Chief of Staff. It defines leadership, leadership roles and requirements, and how to develop leadership within the Army. It outlines the levels of leadership as direct, organizational, and strategic, and describes how to lead successfully at each level. It establishes and describes the core leader competencies that facilitate focused feedback, education, training, and development across all leadership levels. It reiterates the Army Values. FM 6-22 defines how the Warrior Ethos is an integral part of every Soldier's life. It incorporates the leadership qualities of self-awareness and adaptability and describes their critical impact on acquiring additional knowledge and improving in the core leader competencies while operating in constantly changing operational environments.In line with evolving Army doctrine, FM 6-22 directly supports the Army's capstone manuals, FM 1 and FM 3-0, as well as keystone manuals such as FM 5-0, FM 6-0, and FM 7-0. FM 6-22 connects Army doctrine to joint doctrine as expressed in the relevant joint doctrinal publications, JP 1 and JP 3-0. As outlined in FM 1, the Army uses the shorthand expression of BE-KNOW-DO to concentrate on key factors of leadership. What leaders DO emerges from who they are (BE) and what they KNOW. Leaders are prepared throughout their lifetimes with respect to BE-KNOW-DO so they will be able to act at a moment's notice and provide leadership for whatever challenge they may face.FM 6-22 expands on the principles in FM 1 and describes the character attributes and core competencies required of contemporary leaders. Character is based on the attributes central to a leader's make-up, and competence comes from how character combines with knowledge, skills, and behaviors to result in leadership. Inextricably linked to the inherent qualities of the Army leader, the concept of BE-KNOW-DO represents specified elements of character, knowledge, and behavior described here in FM 6-22.
