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.

Dedicated to the Sailors and Marines who lost their lives on the final voyage of USS Indianapolis and to those who survived the torment at sea following its sinking. plus the crews that risked their lives in rescue ships. The USS Indianapolis (CA-35) was a decorated World War II warship that is primarily remembered for her worst 15 minutes. . This ship earned ten (10) battle stars for her service in World War II and was credited for shooting down nine (9) enemy planes. However, this fame was overshadowed by the first 15 minutes July 30, 1945, when she was struck by two (2) torpedoes from Japanese submarine I-58 and sent to the bottom of the Philippine Sea. The sinking of Indianapolis and the loss of 880 crew out of 1,196 --most deaths occurring in the 4-5 day wait for a rescue delayed --is a tragedy in U.S. naval history. This historical reference showcases primary source documents to tell the story of Indianapolis, the history of this tragedy from the U.S. Navy perspective. It recounts the sinking, rescue efforts, follow-up investigations, aftermath and continuing communications efforts. Included are deck logs to better understand the ship location when she sunk and testimony of survivors and participants.

Does the identification number 60 indicate a toxic substance or a flammable solid, in the molten state at an elevated temperature? Does the identification number 1035 indicate ethane or butane? What is the difference between natural gas transmission pipelines and natural gas distribution pipelines? If you came upon an overturned truck on the highway that was leaking, would you be able to identify if it was hazardous and know what steps to take? Questions like these and more are answered in the Emergency Response Guidebook. Learn how to identify symbols for and vehicles carrying toxic, flammable, explosive, radioactive, or otherwise harmful substances and how to respond once an incident involving those substances has been identified. Always be prepared in situations that are unfamiliar and dangerous and know how to rectify them. Keeping this guide around at all times will ensure that, if you were to come upon a transportation situation involving hazardous substances or dangerous goods, you will be able to help keep others and yourself out of danger. With color-coded pages for quick and easy reference, this is the official manual used by first responders in the United States and Canada for transportation incidents involving dangerous goods or hazardous materials.

Developed and expanded from the work presented at the New Energetic Materials and Propulsion Techniques for Space Exploration workshop in June 2014, this book contains new scientific results, up-to-date reviews, and inspiring perspectives in a number of areas related to the energetic aspects of chemical rocket propulsion. This collection covers the entire life of energetic materials from their conceptual formulation to practical manufacturing; it includes coverage of theoretical and experimental ballistics, performance properties, as well as laboratory-scale and full system-scale, handling, hazards, environment, ageing, and disposal. Chemical Rocket Propulsion is a unique work, where a selection of accomplished experts from the pioneering era of space propulsion and current technologists from the most advanced international laboratories discuss the future of chemical rocket propulsion for access to, and exploration of, space. It will be of interest to both postgraduate and final-year undergraduate students in aerospace engineering, and practicing aeronautical engineers and designers, especially those with an interest in propulsion, as well as researchers in energetic materials.

Engineering Metrology and Measurements is a textbook designed for students of mechanical, production and allied disciplines to facilitate learning of various shop-floor measurement techniques and also understand the basics of mechanical measurements.

Fought over the course of four years, the Civil War pitted countrymen against countrymen, North versus South, friend against friend, and brother against brother. The photographs within these pages document the war that united America as one. These rare shots were taken in the middle of the battlefield during the earliest days of photography. Selected from a collection of seven thousand original negatives, these historic photos capture nearly every aspect of Civil War life. Among these photos are images of camps sprawling across acres, soldiers at their battlements, firing of heavy artillery, the aftermath of battle, and the terror that these young men faced. See first-hand of Union and Confederate officers strategizing their next moves, and Abraham Lincoln addressing his Union commanders. Originally released from the private collection of Edward Bailey Eaton in 1907, this edition is a must have for any Civil War buff or historian. No collection can be considered complete without these photographs by Matthew Brady and Alexander Gardner, as well as the meticulous passages that put the images in illuminating context.
