What is one of the capstone doctrine manuals for the Army?

The capstone doctrine manuals for the Army establish overarching principles and key strategic guidance for Army operations, and among them, ADP 3-0 is fundamental. This manual outlines the Army's operational concept and describes how the Army supports national security objectives through its mission. It integrates the principles of unified land operations, emphasizing the importance of combined arms and joint operations, while also addressing the need for adaptability in response to the changing nature of warfare.

The distinction of ADP 3-0 lies in its role as a comprehensive framework for understanding and conducting operations, which is essential for Army leaders at all levels. Its focus on a holistic approach to military operations makes it the appropriate selection as a capstone doctrine manual, guiding all other doctrine and operations within the Army.
