For the US Army to succeed in the 21st Century, Soldiers of all ranks must understand and use Mission Command. Mission Command empowers leaders at all levels, allowing them to synchronize all warfighting functions and information systems to seize, retain, and exploit the initiative against a range of adversaries. This collection of historical vignettes seeks to sharpen our understanding of Mission Command philosophy and practice by providing examples from the past in which Mission Command principles played a decisive role. Some vignettes show junior officers following their commander's intent and exercising disciplined initiative in very chaotic combat operations. Others recount how field grade officers built cohesive teams that relied on mutual trust to achieve key operational objectives. Each historical account is complemented by an annotated explanation of how the six Mission Command principles shaped the action. For this reason, the collection is ideal for leader development in the Army school system as well as for unit and individual professional development. Mission Command places great responsibility on our Soldiers.

From the introduction: "In early 2013, the Combat Studies Institute became involved in this effort by writing a series of Mission Command case studies for use at the US Army's Joint Readiness Training Center (JRTC) at Fort Polk. Those case studies form the core of this collection. Each case includes a brief account of a military action followed by an explanatory section that demonstrates how the case illustrates Mission Command principles. This structure was designed for use in training and schools but is equally conducive for self-study programs. None of the 16 cases in this volume offer examples of leaders practicing Mission Command perfectly. Some of the actions described, in fact, come from early periods in which the lack of radio and other modern communications made any level of command and control very difficult to attain. The real value of these cases lies in their ability to clearly convey how past leaders employed principles such as the use of commander's intent and the exercise of disciplined initiative to seize, retain, and exploit the initiative. In this way, the past breathes life into current doctrine, making it more tangible and understandable. "

The book tells the story of the theory and history of the mission command approach (decentralized command) and the attempts by different armies to adopt and reform according to this approach.

In 1950, when he commissioned the first edition of The Armed Forces Officer, Secretary of Defense George C. Marshall told its author, S.L.A. Marshall, that "American military officers, of whatever service, should share common ground ethically and morally." In this new edition, the authors methodically explore that common ground, reflecting on the basics of the Profession of Arms, and the officer's special place and distinctive obligations within that profession and especially to the Constitution.
