Each book studies the organization, actions and strength of a major unit in battle, describing elements of doctrine, training, tactics, equipment and deployment. Detailed orders of battle, tables of organization and equipment, maps and diagrams support each text.

Battle Orders break down military units into their constituent parts, revealing how individual fighting strength, combat missions and command decisions combine to determine the course of major battles and wars. The scope of each book ranges from armies to divisions or battalions, and from wars to theatres of war and campaigns.
