Following three successful editions, the fourth edition of this book provides concise, updated guidance and procedures for providing logistical support to a deployed army on 21st-century battlefields.

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.
