Combat helmets have evolved considerably over the years from those used in World War I to today's Advanced Combat Helmet. One of the key advances was the development of aramid fibers in the 1960s, which led to today's Kevlar-based helmets. The Department of Defense is continuing to invest in research to improve helmet performance, through better design and materials as well as better manufacturing processes.

Review of the Department of Defense Test Protocols for Combat Helmets considers the technical issues relating to test protocols for military combat helmets. At the request of the DOD Director of Operational Test and Evaluation, this report evaluates the adequacy of the Advanced Combat Helmet test protocol for both first article testing and lot acceptance testing, including its use of the metrics of probability of no penetration and the upper tolerance limit (used to evaluate backface deformation). The report evaluates appropriate use of statistical techniques in gathering data; adequacy of current helmet testing procedures; procedures for the conduct of additional analysis of penetration and backface deformation data; and scope of characterization testing relative to the benefit of the information obtained.

Success in war has always been difficult to measure. What is judged successful by military leaders may not be judged so by political leadership, nor by the wider public, at least in a Western-style democracy. The public is generally inclined to applaud military victory, but it instinctively reserves the right to ask afterwards: Was it really worth it? In Political Victory, Brian Crozier looks at modern wars involving democracies to evaluate victory and defeat by the success or failure of political outcomes.Crozier begins with the two world wars, where in both cases the German aggressor was defeated by three key democracies: the United States, the United Kingdom, and France. In World War I military victory was squandered by treaty terms that led to the advent of Hitler and Nazism. By contrast, the total defeat of Nazism in 1945 left the Western Allies in charge of some two-thirds of Germany's population, thus enabling the victors to convert the vanquished to democracy. Crozier also deals with the break up of empires following World War II, comparing how Britain avoided full-scale war in contrast with France's violent confrontations in Southeast Asia and Algeria.America's involvement in Vietnam is analyzed in the wider context of the Cold War and the mounting challenge of international communism to Western democracies. His assessment stresses the lack of popularity in America for the idea of democratizing a region to which the U.S. has no historical or sentimental attachment. Among the smaller conflicts considered in this volume are the Suez crisis of 1956, the Falkland Island war between Britain and Argentina, and the fateful Soviet involvement in Afghanistan that helped bring about the collapse of the Soviet system. Crozier concludes with analyses of the 1991 Gulf War and the Western intervention in the former Yugoslavia.Crozier's final chapters focus on looming threats around the world with particular emphasis on international terrorism and the challenge of radical Islam. Both historical and timely, Political Victory will be of interest to military historians, political scientists, and foreign affairs specialists.
 Examines why many governments, rebels, and terrorist organizations are using children as soldiers.
Despite the supposed taboo against the practice, many governments, rebels, and terrorist groups use children in war to spy and kill. In Tools of War, Tools of State, Robert Tynes examines this complex problem, demonstrating that the modern use of children in war is a tactical innovation. He discusses how boys and girls on the battlefield bolster troop size, create moral dilemmas, and deepen the level of fear. He also reveals how the practice has become an essential component for groups such as ISIS and al-Shabaab, in their state-making projects. Using statistical methods to analyze conflicts from 1987 to 2007, Tynes shows how widespread child soldier use is and confirms the theory that it is tactically advantageous. Through historical analysis, he explains how child soldiering developed out of Mao’s protracted war theory and the militarization of youth during the twentieth century. A case study of the civil war in Sierra Leone, which details the brutality involved when children are forced to fight, is included.

“Robert Tynes has written the most comprehensive and thorough explanation to date of how and why children become involved in war. Examining the problem from both qualitative and quantitative perspectives, he does a superb job of showing the ways in which children are exploited by states and nonstate actors to carry out the most heinous forms of political violence.” — Mia Bloom, author of Dying to Kill: The Allure of Suicide Terror and Bombshell: Women and Terrorism

“Tools of War, Tools of State explores the often overlooked but extremely important issue of the use of child soldiers, shedding light on why insurgents are motivated to bring children into their ranks, give them guns, and put them on the battlefield.” — Victor Asal, author of Legal Path Dependence and the Long Arm of the Religious State: Sodomy Provisions and Gay Rights across Nations and over Time

“Robert Tynes makes an important contribution to one of the most critical humanitarian issues of our time: the use of child soldiers in combat. He does a masterful job examining why both governments and rebel groups choose to use child soldiers and exploring his innovative argument using a range of methods from ethnographic interviews and case studies to network and regression analyses. The book will be of interest to academics, students, and policy professionals.” — David L. Rousseau, author of Democracy and War: Institutions, Norms, and the Evolution of International Conflict

The confluence of the September 11, 2001 terrorist attack and the U.S. Army’s historic role to support civil authorities has resulted in substantial new challenges for the Army. To help meet these challenges, the Assistant Secretary of the Army for Research and Technology requested the National Research Council (NRC) carry out a series of studies on how science and technology could assist the Army prepare for its role in homeland security (HLS). The NRC’s Board on Army Science and Technology formed the Committee on Army Science and Technology for Homeland Security to accomplish that assignment. The Committee was asked to review relevant literature and activities, determine areas of emphasis for Army S&T in support of counter terrorism and anti-terrorism, and recommend high-payoff technologies to help the Army fulfill its mission. The Department of Defense Counter-Terrorism Technology Task Force identified four operational areas in reviewing technical proposals for HLS operations: indications and warning; denial and survivability; recovery and consequence management; and attribution and retaliation. The study sponsor asked the Committee to use these four areas as the basis for its assessment of the science and technology (S&T) that will be important for the Army’s HLS role. Overall, the Committee found that: - There is potential for substantial synergy between S&T work carried out by the Army for its HLS responsibilities and the development of the next generation Army, the Objective Force. - The Army National Guard (ARNG) is critical to the success of the Army’s HLS efforts.
