outreach programs. Computational and Information Sciences The Computational and Information Sciences Directorate (CISD) is the foremost U.S. Army organization for research and development of modern electronic systems. This research supports capabilities in the analysis, distribution, and assimilation of real or simulated digitized battlefield information. In addition to the digitized war initiatives, high performance computing research is performed at a variety of centers under the ARL. The use of supercomputers for mathematical simulations instead of mass fabrication can result in the conservation of human and physical resources. The directorate is a key player in the International Technology Alliance in conjunction with SEDD and HRED directorates. Human Research and Engineering The U.S. Army Research Laboratory's Human Research and Engineering Directorate (HRED) is the principal Army organization for research and development (R&D) in the human dimension. HRED conducts a broad-based program of scientific research and technology directed toward optimizing Soldier performance and Soldier-machine interactions to maximize battlefield effectiveness. HRED also executes an analysis mission that provides the Army with human factors leadership to ensure that Soldier performance requirements are adequately considered in technology development and system design. HRED coordinates technologies within the Army, other services and their laboratories, industry, and academia to leverage basic and applied research opportunities for the benefit of the Army. Sensors and Electron Devices Sensors and Electron Devices Directorate (SEDD) is a group dedicated to produce equipment from tiny chips to fully integrated systems. SEDD also helps develop sensors and electronic devices which become an important part of modern warfare. Other components of this directorate include: multifunction radio frequency equipment, autonomous sensing, power generation and management, and signal processing algorithms. One of the best ways to protect the soldier is to develop autonomous sensing systems for all activities, from intelligence gathering to waging warfare. Survivability/Lethality Analysis The Survivability/Lethality Analysis Directorate (SLAD) is the primary center for expertise in survivability, lethality, and vulnerability of all army systems, across the full range of battlefield threats: ballistic, electronic warfare, information operations, and nuclear, biological, and chemical warfare. SLAD's mission is to assist technology and system developers in optimizing system designs and to provide analytical data to evaluators and decision makers in the Army and the DOD. Vehicle Technology The U.S. Army Research Laboratory's Vehicle Technology Directorate (VTD) manages research and development of vehicle propulsion and structure. In addition, VTD conducts analytical and practical experiments in loads analysis, structural dynamics, aero-elasticity, structural acoustics,
