Available in PDF, EPUB and Kindle. Book excerpt: This book is part of the Army historical community's commemoration of the fiftieth anniversary of World War II. American victory in that conflict was brought about not only by the valor of our fighting men and the immensity of our productive capacity, but also by the availability of superb military intelligence. Much of this intelligence came from the ability of our armed forces to intercept and decipher the most secret communications of their adversaries. For many years security considerations prevented any public mention of these successes in the office histories. Now much of the story can be told. To preserve the memory of the Army's role in this intelligence war, a collection of documents on Army signals intelligence in World War II Signal II were published. This book is intended both for an Army audience and for the general public - including those World War II veterans who participated in the signals intelligence war and who for so many years were constrained to keep their contributions secret. The security barriers have now been lifted, and the Army is proud to acknowledge those contributions.

Book excerpt: This study traces the development of American radio intelligence at the operational and tactical levels from its beginnings in World War I through the end of World War II. It shows that signals intelligence is useful to the tactical and operational level commander. The study recommends the Army rethink signal intelligence support to the various echelons, primarily through changes to tables of organization and equipment. The thesis covers the initial appearance of radio intelligence units on the battlefields of France in the first world war, identifying specific instances where radio intelligence played a role in a command decision. It also looks at training and doctrine in the period between the two world wars. The thesis also covers the organization, doctrine, and training of radio intelligence units as they prepared for combat. It provides a glimpse into the intelligence support provided to the corps, army, and army group commanders during World War II through examination of actual intercept operations. Where possible the study compares and contrasts German radio intelligence units and operations with their American counterparts.

How was radio intelligence used at the operational and tactical levels during World War II? How did American radio intelligence compare to German units and operations? What lessons did we learn, and what is the effect of those lessons on today's forces? At every echelon, division, corps, and theater army, there are military intelligence (MI) units with the sole purpose of providing signals intelligence support to the commander. One Combat Electronic Warfare and Intelligence (CEWI) battalion directly supports a division; two MI battalions (the Technical Exploitation and the Aerial Exploitation) support a corps; and two MI Battalions (SIGINT) support theater armies worldwide. The roots of these units can be found in the radio intelligence and signal service companies from World War II. No classified material was used in the thesis. While simplifying research, classification problems arose in an unexpected arena. It appears that few operational records (those with actual intercept logs, message contents, etc.) were saved after the war. Two units, after writing their after action reports, destroyed their operational logs because of security reasons, but also to reduce the amount of baggage to take home. This created a gap in tracing how any intercepted material became intelligence briefed to a commander.

Book excerpt: SIGNALS INTELLIGENCE, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War.In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty’s famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers."SIGINT is a fascinating account of what Allied investigators learned postwar about the Nazi equivalent of Bletchley Park. Turns out, 60,000 crptographers, analysts and linguists achieved considerable success in solving intercepted traffic, and even broke the Swiss Enigma! Based on recently declassifed NSA document, this is a great contribution to the literature." THE ST ERMIN'S HOTEL INTELLIGENCE BOOK OF THE YEAR AWARD 2014.

Book excerpt: "...a comprehensive reprint of the Intelligence doctrine that supported the American drive to victory on numerous fronts against a wide range of enemies and environments. It is worth the read to reinforce the basics of what we still do today." — The Vanguard: Journal of the Military Intelligence Corps Association On December 7, 1941, an imperial Japanese carrier strike force attacked the US Pacific Fleet at Pearl Harbor, taking advantage of what was one of the most profound intelligence failures in US history. Galvanized into action, the branches of the U.S. military subsequently developed one of the greatest, albeit imperfect, intelligence-gathering and analysis networks of the combatant nations, opening an invaluable window onto the intentions of their enemies. The picture of U.S. military intelligence during World War II is a complex one. It was divided between the fields of signal intelligence (SIGINT) and human intelligence (HUMINT), combat intelligence and War Department intelligence, and between numerous different organizations, including the Military Intelligence Division (MID), Military Intelligence Service (MIS), the Office of Naval Intelligence (ONI), the Counter Intelligence Corps (CIC), the Office of Strategic Services (OSS) and the many intelligence units organic to Army, Navy, Army Air Forces, and Marine Corps. The documents collected in this book reveal the theoretical and practical principles behind wartime intelligence gathering and analysis, from the frontline intelligence officer to the Washington-based code-breaker. They explain fundamentals such as how to observe and record enemy activity and intercept enemy radio traffic, through to specialist activities such as cryptanalysis, photoreconnaissance, prisoner interrogation, and undercover agent operations. The painstaking work of an intelligence operator required a sharp, attentive mind, whether working behind a desk or under fire on the frontlines. The outputs from these men and women could ultimately make the difference between victory and defeat in battle.
Download or read book American Signal Intelligence in Northwest Africa and Western Europe written by George Howe and published by CreateSpace. This book was released on 2012-08-01 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume at hand, Dr. George F. Howe's American Signals Intelligence in Northwest Africa and Western Europe is important professional reading for those interested in cryptologic history or in World War II. Dr. Howe's book deals primarily with organizational matters for providing SIGINT support in combat. Thus, the reader will not find stories of high-level cryptanalysis underlying big decisions by famous leaders. In my estimation, by concentrating on the less flashy aspects of wartime support in favor of the background work, Dr. Howe has again added a dimension of great worth to our knowledge of SIGINT and of the war. The study of World War II SIGINT has concentrated, by and large, on ULTRA, the exploitation of high-grade cryptographic systems used by Germany and Japan, and the use of ULTRA material by senior wartime decision makers. This effort unquestionably is important for understanding the decisions and events of that terrible era, but the overwhelming focus on this aspect has resulted in a slightly skewed understanding. The production of ULTRA and its effective use depended on a strong and well-organized structure working in conjunction with now-legendary cryptanalysts. Since the distribution of ULTRA was limited to a small number of officers and civilian leaders, the bulk of SIGINT support to the warfighter cam from tactical SIGINT units working at or near the front lines. This is an important subject for understanding what happened in World War II and for studying the principles of SIGINT organization today.

Download or read book Signal Security In The Ardennes Offensive 1944 1945 written by Major Laurie G. Moe Buckhout and published by Pickle Partners Publishing. This book was released on 2015-11-06 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the significance, theory and practice of tactical signal security (SIGSEC) during the Ardennes Offensive of 1944-1945. The work includes a brief introduction to the offensive and to the history of SIGSEC, and examines how the American and German armies safeguarded communications from the enemy. Inherent in this study was an investigation of actions taken by these armies to exploit their adversary’s SIGSEC and the processing and exploitation of the signal intelligence (SIGINT) they obtained. The study concludes that both armies had similar equipment, basic procedures, and training in the areas of communications, SIGSEC and SIGINT, and suffered similar deficiencies in these areas. Analysis, however, revealed a deep disparity concerning their use and importance. The Americans’ near complete lack of regard for tactical SIGINT was a major factor contributing to the success of Hitler’s deception. The U.S. Army relied heavily upon intelligence gleaned from the German ULTRA code, and American intelligence officers were untrained in the use of tactical signal intelligence, mainly using it to validate operational plans. This attitude is reflected also in the American emphasis on SIGSEC. The Germans, however, were more experienced in SIGINT and SIGSEC, and formed a structure and doctrine that focused on immediately influencing tactical operations.
Download or read book Piercing the Fog written by John F. Kreis and published by Military Bookshop. This book was released on 2013-05 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the foreword: WHEN JAPAN ATTACKED PEARL HARBOR on December 7, 1941, and Germany and Italy joined Japan four days later in declaring war against the United States, intelligence essential for the Army Air Forces to conduct effective warfare in the European and Pacific theaters did not exist. Piercing the Fog tells the intriguing story of how airmen built intelligence organizations to collect and process information about the enemy and to produce and disseminate intelligence to decisionmakers and warfighters in the bloody, horrific crucible of war. Because the problems confronting and confounding air intelligence officers, planners, and operators fifty years ago still resonate, Piercing the Fog is particularly valuable for intelligence officers, planners, and operators today and for anyone concerned with acquiring and exploiting intelligence for successful air warfare. More than organizational history, this book reveals the indispensable and necessarily secret role intelligence plays in effectively waging war. It examines how World War II was a watershed period for Air Force Intelligence and for the acquisition and use of signals intelligence, photo reconnaissance intelligence, human resources intelligence, and scientific and technical intelligence. Piercing the Fog discusses the development of new sources and methods of intelligence collection; requirements for intelligence at the strategic, operational, and tactical levels of warfare; intelligence to support missions for air superiority, interdiction, strategic bombardment, and air defense; the sharing of intelligence in a coalition and joint service environment; the acquisition of intelligence to assess bomb damage on a target-by-target basis and to measure progress in achieving campaign and war objecti ves; and the ability of military leaders to understand the intentions and capabilities of the enemy and to appreciate the pressures on intelligence officers to sometimes tell commanders what they think the commanders want to hear instead of what the intelligence discloses. The complex problems associated with intelligence to support strategic bombardment in the 1940s will strike some readers as uncannily prescient to global Air Force operations in the 1990s.," Illustrated.
