The Dismounted Warrior Branch of the Human Research and Engineering Directorate conducts research in biomechanics, human movement science, and/or kinesiology. Our biomechanics program focuses on understanding the effects of equipment on solider and soldier-system performance. Specifically, we examine solider-equipment issues for dismounted soldiers (i.e., soldiers not riding in vehicles). Biomechanical analyses are used to minimize the negative effects of this equipment and to provide design guidance for maximizing the positive effects. Our current biomechanics laboratory is being replaced by a state-of-the-art 2700 square foot biomechanics lab with an integrated force plate treadmill, portable cardio-pulmonary and EMG systems, and motion capture system. This new biomechanics lab is part of our new Soldier Performance and Equipment Advanced Research (SPEAR) Facility, which was designed to study the interaction between physical and cognitive stress and performance. Additional biomechanical research is conducted in our Tactical Environmental Simulation Facility (with an omni-directional treadmill), our Dismounted Infantry Survivability and Lethality Testbed (weapons simulator), and our live fire range.
