A manual of United States Army ordnance.

A collection of drawings, tables, and descriptions of artillery, artillery supplies, and ordnance available to the U.S. Army in its land service.

This paper focuses on the formulation of doctrine since World War II. In no comparable period in history have the dimensions of the battlefield been so altered by rapid technological changes. The need for the tactical doctrines of the Army to remain correspondingly abreast of these changes is thus more pressing than ever before. Future conflicts are not likely to develop in the leisurely fashions of the past where tactical doctrines could be refined on the battlefield itself. It is, therefore, imperative that we apprehend future problems with as much accuracy as possible. One means of doing so is to pay particular attention to the business of how the Army's doctrine has developed historically, with a view to improving methods of future development.

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.

In the seventy years that have passed since the tank first appeared, antitank combat has presented one of the greatest challenges in land warfare. Dramatic improvements in tank technology and doctrine over the years have precipitated equally innovative developments in the antitank field. One cycle in this ongoing arms race occurred during the early years of World War II when the U.S. Army sought desperately to find an antidote to the vaunted German blitzkrieg. This Leavenworth Paper analyzes the origins of the tank destroyer concept, evaluates the doctrine and equipment with which tank destroyer units fought, and assesses the effectiveness of the tank destroyer in battle.

George C. Marshall once called him "the brains of the army." And yet General Lesley J. McNair (1883-1944), a man so instrumental to America's military preparedness and Army modernization, remains little known today, his papers purportedly lost, destroyed by his wife in her grief at his death in Normandy. This book, the product of an abiding interest and painstaking research, restores the general Army Magazine calls one of "Marshall's forgotten men" to his rightful place in American military history. Because McNair contributed so substantially to America's war preparedness, this first complete account of his extensive and varied career also leads to a reevaluation of U.S. Army effectiveness during WWII. Born halfway between the Civil War and the dawn of the 20th century, Lesley McNair–"Whitey" by his classmates for his blond hair–graduated 11th of 124 in West Point's class of 1904 and rose slowly through the ranks like all officers in the early twentieth century. He was 31 when World War I erupted, 34 and a junior officer when American troops prepared to join the fight. It was during this time, and in the interwar period that followed the end of the First World War, that McNair's considerable influence on Army doctrine and training, equipment development, unit organization, and combined arms fighting methods developed. By looking at the whole of McNair's career–not just his service in WWII as chief of staff, General Headquarters, 1940-1942, and then as commander, Army Ground Forces, 1942-1944–Calhoun reassesses the evolution and extent of that influence during the war, as well as McNair's, and the Army's, wartime performance. This in-depth study tracks the significantly positive impact of McNair's efforts in several critical areas: advanced officer education; modernization, military innovation, and technological development; the field-testing of doctrine; streamlining and pooling of assets for necessary efficiency; arduous and realistic combat training; combined arms tactics; and an increasingly mechanized and mobile force. Because McNair served primarily in staff roles throughout his career and did not command combat formations during WWII, his contribution has never received the attention given to more public–and publicized–military exploits. In its detail and scope, this first full military biography reveals the unique and valuable perspective McNair's generalship offers for the serious student of military history and leadership.
