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.

With the centennial of the First World War rapidly approaching, historian and bibliographer James T. Controvich offers in The United States in World War I: A Bibliographic Guide the most comprehensive, up-to-date reference bibliography yet published. Organized by subject, this bibliography includes the full range of sources: vintage publications of the time, books, pamphlets, periodical titles, theses, dissertations, and archival sources held by federal and state organizations, as well as those in public and private hands, including historical societies and museums. As Controvich’s bibliographic accounting makes clear, there were many facets of World War I that remain virtually unknown to this day. Throughout, Controvich’s bibliography tracks the primary sources that tell each of these stories—and many others besides—during this tense period in American history. Each entry lists the author, title, place of publication, publisher, date of publication, and page count as well as descriptive information concerning illustrations, plates, ports, maps, diagrams, and plans. The armed forces section carries additional information on rosters, awards, citations, and killed and wounded in action lists. The United States in World War I: A Bibliographic Guide is an ideal research tool for students and scholars of World War I and American history.
