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.

German defenses along the Normandy beaches were part of the larger Atlantic Wall fortifications designed to defend Fortress Europe. When Field Marshal Erwin Rommel took command of the invasion front in late 1943, he began a program to enhance fortifications along the Normandy coast as he believed that any Allied assault had to be stopped on the invasion beaches themselves. His most important contribution to the defenses was an extensive program of improvised beach obstructions to complicate any landing attempt. This book analyses these fortifications and describes how the Allied forces overcame them on the morning of June 6, 1944.

This manual provides guidance for the organization, planning, and conduct of the full range of military operations on urbanized terrain. This publication was prepared primarily for commanders, staffs, and subordinate leaders down to the squad and fire team level. It is written from a Marine air-ground task force perspective, with emphasis on the ground combat element as the most likely supported element in that environment. It provides the level of detailed information that supports the complexities of planning, preparing for, and executing small-unit combat operations on urbanized terrain. It also provides historical and environmental information that supports planning and training for combat in built-up areas
