Review of Department of Defense Test Protocols for Combat Helmets
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 Congress, 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.
Making the Soldier Decisive on Future Battlefields
The U.S. military does not believe its soldiers, sailors, airmen, and marines should be engaged in combat with adversaries on a "level playing field." Our combat individuals enter engagements to win. To that end, the United States has used its technical prowess and industrial capability to develop decisive weapons that overmatch those of potential enemies. In its current engagement—what has been identified as an "era of persistent conflict"— the nation's most important weapon is the dismounted soldier operating in small units. Today's soldier must be prepared to contend with both regular and irregular adversaries. Results in Iraq and Afghanistan show that, while the U.S. soldier is a formidable fighter, the contemporary suite of equipment and support does not afford the same high degree of overmatch capability exhibited by large weapons platforms—yet it is the soldier who ultimately will play the decisive role in restoring stability.
Making the Soldier Decisive on Future Battlefields establishes the technical requirements for overmatch capability for dismounted soldiers operating individually or in small units. It prescribes technological and organizational capabilities needed to make the dismounted soldier a decisive weapon in a changing, uncertain, and complex future environment and provides the Army with 15 recommendations on how to focus its efforts to enable the soldier and tactical small unit (TSU) to achieve overmatch.

Testing of Body Armor Materials: Phase III
In 2009, the Government Accountability Office (GAO) released the report Warfighter Support: Independent Expert Assessment of Army Body Armor Test Results and Procedures Needed Before Fielding, which commented on the conduct of the test procedures governing acceptance of body armor vest-plate inserts worn by military service members. This GAO report, as well as other observations, led the Department of Defense Director, Operational Test & Evaluation, to request that the National Research Council (NRC) Division on Engineering and Physical Sciences conduct a three-phase study to investigate issues related to the testing of body armor materials for use by the U.S. Army and other military departments. Phase I and II resulted in two NRC letter reports: one in 2009 and one in 2010. This report is Phase III in the study.
Testing of Body Armor Materials: Phase III provides a roadmap to reduce the variability of clay processes and shows how to migrate from clay to future solutions, as well as considers the use of statistics to permit a more scientific determination of sample sizes to be used in body armor testing. This report also develops ideas for revising or replacing the Prather study methodology, as well as reviews comments on methodologies and technical approaches to military helmet testing. Testing of Body Armor Materials: Phase III also considers the possibility of combining various national body armor testing standards.
Opportunities in Protection Materials Science and Technology for Future Army Applications
This report explores the current theoretical and experimental understanding of the key issues surrounding protection materials, identifies the major challenges and technical gaps for developing the future generation of lightweight protection materials, and recommends a path forward for their development. It examines multiscale shockwave energy transfer mechanisms and experimental approaches for their characterization over short timescales, as well as multiscale modeling techniques to predict mechanisms for dissipating energy. The report also considers exemplary threats and design philosophy for the three key applications of armor systems: (1) personnel protection, including body armor and helmets, (2) vehicle armor, and (3) transparent armor.
The committee recommends that the Department of Defense (DoD) establish a defense initiative for protection materials by design (PMD), with associated funding lines for basic and applied research. The PMD initiative should include a combination of computational, experimental, and materials testing, characterization, and processing research conducted by government, industry, and academia.
| 2010|| |

More detailed evaluations of the array of issues surrounding body armor testing, both present and future, will be presented in the final Phase III report.
| 2009|| |
The National Research Council of the National Academies established a study to assess the methodologies used by the U.S. Army for the testing of body armor. This Phase I report is focused primarily on the validity of laser-profiling techniques for body armor test measurements. More comprehensive and detailed evaluations of an array of issues surrounding body armor testing will be presented in the forthcoming Phase II and Phase III reports.
Opportunities in Neuroscience for Future Army Applications
Advances and major investments in the field of neuroscience can enhance traditional behavioral science approaches to training, learning, and other applications of value to the Army. Neural-behavioral indicators offer new ways to evaluate how well an individual trainee has assimilated mission critical knowledge and skills, and can also be used to provide feedback on the readiness of soldiers for combat. Current methods for matching individual capabilities with the requirements for performing high-value Army assignments do not include neuropsychological, psychophysiological, neurochemical or neurogenetic components; simple neuropsychological testing could greatly improve training success rates for these assignments.
Opportunities in Neuroscience for Future Army Applications makes 17 recommendations that focus on utilizing current scientific research and development initiatives to improve performance and efficiency, collaborating with pharmaceutical companies to employ neuropharmaceuticals for general sustainment or enhancement of soldier performance, and improving cognitive and behavioral performance using interdisciplinary approaches and technological investments. An essential guide for the Army, this book will also be of interest to other branches of military, national security and intelligence agencies, academic and commercial researchers, pharmaceutical companies, and others interested in applying the rapid advances in neuroscience to the performance of individual and group tasks.
Review of Directed Energy Technology for Countering Rockets, Artillery, and Mortars (RAM): Abbreviated Version
The United States Army is looking for ways to defend against missile and mortar attacks. In this book, the National Research Council assesses a plan to create a 100 kW mobile, solid-state, laser weapon that could defend an area several kilometers in diameter.
The NRC provides several recommendations:
- A 100 kW Laser is of limited value, so the program's goal should be a 400 kW weapon.
- The Army should proceed with the program in stages, focusing first on a rugged transportable platform for the weapon using existing 25 kW laser technology, then directing resources toward 100kW and 400 kW weapons.
- The Army should perform a detailed, quantitative study of the effectiveness of a high energy, solid-state laser weapon against future threats.
- The Army should continue to participate in U.S.-based and international research on high-energy lasers and related equipment. The committee found substantial benefits for the Army's solid-state laser program from other programs outside the Army.
- The Army should conduct risk-assessments that investigate the effects that a high energy laser may have on other airborne platforms in the vicinity of the target.
- The Army should study eye safety for both the operators of the laser and for civilians. The results of these studies should be integrated into the development of the weapon.
|Strategy for an Army Center for Network Science, Technology, and Experimentation |
The U.S. military has committed to a strategy of network-centric warfare. As a result, the Army has become increasingly interested in the critical role of network science. To a significant extent, this interest was stimulated by an earlier NRC report, Network Science. To build on that report, the Army asked the NRC to conduct a study to define advanced operating models and architectures for future Army laboratories and centers focused on network science, technologies, and experimentation (NSTE). The challenges resulting from base realignment and closure (BRAC) relocations of Army research, development, and engineering resources—as they affected the NSTE program—were also to be a focus of the study. This report provides a discussion of what NSTE is needed by the Army; an examination of the NSTE currently carried out by the Army; an assessment of needed infrastructure resources for Army NSTE; and an analysis of goals, models, and alternatives for an NSTE center.
|Network Science |
The U.S. Army depends on a broad array of interacting physical, informational, cognitive, and social networks. Nevertheless, fundamental understanding about these networks is primitive. This gap between what is known and what is needed to ensure the smooth operation of complex networks makes the Army's transformation to a force capable of network-centric operations (NCO) problematic. To help address this problem, the Army asked the National Research Council to find out whether identifying and funding ï¿½network scienceï¿½ research could help close this gap. This book presents an assessment of the importance and content of network science as it exists today. The book also provides an analysis of how the Army might advance the transformation to NCO operations by supporting fundamental research on networks. The study finds that networks are indispensable to the defense of the United States. In addition, there is no science today that offers the fundamental knowledge necessary to design large, complex networks in a predictable manner. The study also concluded that current federal funding of network research is focused on specific applications and not on advancing fundamental knowledge.

|Army Science and Technology for Homeland Security: Report 2–C4ISR |
Shortly after the events of September 11, 2001, the U.S. Army asked the National Research Council (NRC) to study how science and technology could assist the Army meet its Homeland defense obligations. The first report, Science and Technology for Army Homeland Security—Report 1, presented a survey of a broad range of technologies and recommended applying Future Force technologies to homeland security wherever possible. In particular, the report noted that the Army should play a major role in providing emergency command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) capabilities and that the technology and architecture needed for homeland security C4ISR was compatible with that of the Army’s Future Force. This second report focuses on C4ISR and how it can facilitate the Army’s efforts to assist the Department of Homeland Security (DHS) and emergency responders meet a catastrophic event.
|Meeting the Energy Needs of Future Warriors |
The central characteristic of the evolution of the combat soldier in recent years is an increasingly sophisticated array of sensing, communications, and related electronics for use in battlefield situations. The most critical factor for maintaining this evolution will be the development of power supply systems capable of operating those electronics effectively for missions up to 72 hours long. To address the challenge, it is important that new approaches be sought on how to integrate and power these electronics. To assist in addressing this problem, the Army requested the National Research Council to review the state of the art and to recommend technologies that will support the rapid development of effective power systems for the future warrior. This report presents the results of that review. It provides an assessment of various technology options for different power level requirements, power system design, and soldier energy sinks. The report also describes future design concepts, focusing on low-power systems. Recommendations for technology development and system design are presented.

|Science and Technology for Army Homeland Security: Report 1 |
The confluence of the September 11, 2001 terrorist attack and the U.S. Armyï¿½s 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 Armyï¿½s HLS efforts.

Alternative Technologies to Replace Antipersonnel Landmines
This report examines potential technologies for replacing antipersonnel landmines by 2006, the target date the United States set in the late 1990s for signing an international treaty banning these weapons if suitable alternatives were available. Alternative Technologies to Replace Antipersonnel Landmines emphasizes the role that technology can play to allow certain weapons to be used more selectively, reducing the danger to uninvolved civilians while improving the effectiveness of the U.S. military. Landmines are an important weapon in the U.S. military's arsenal but their indiscriminate nature poses risks to civilians and friendly forces. Some varieties remain active for many years, posing further risks of unintended casualties. New technologies could replace some, but not all, of the U.S. military's antipersonnel landmines by 2006. In the period following 2006, emerging technologies might eliminate landmines totally, while retaining the necessary functions that current mines provide to the military.
