This United States Army War College, School of Strategic Landpower, Department of Command, Leadership, and Management manuscript, Responsible Command: Primer for Senior Leaders, is divided into three parts. Part I provides two chapters with two distinctly different purposes. Chapter 1 details the issues and concerns about the conflation of command with leadership in military education and the historical origins of responsible command in the laws of land warfare. Chapter 2 is a case study in responsible dissent by prominent military historian Con Crane who tells the story of General Matthew Ridgway and his opposition to the "New Look" strategy by President Eisenhower. The case study illustrates the meaning of responsibility extending beyond that of command positions and the commanders that hold them. Part II is the study of responsible command itself. Part III provides the implications for leader development.
