This book looks at several troop categories based on primary function and analyzes the ratio between these categories to develop a general historical ratio. This ratio is called the Tooth-to-Tail Ratio. McGrath's study finds that this ratio, among types of deployed US forces, has steadily declined since World War II, just as the nature of warfare itself has changed. At the same time, the percentage of deployed forces devoted to logistics functions and to base and life support functions have increased, especially with the advent of the large-scale of use of civilian contractors. This work provides a unique analysis of the size and composition of military forces as found in historical patterns. Extensively illustrated with charts, diagrams, and tables.

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.
