The Integrated Unit Simulation System: Quantifying Individual and Small Unit Mission Effectiveness on the Battlefield of the Future

The US Army Natick Research Development & Engineering Center is developing the Integrated Unit Simulation System (IUSS) in response to a recognized need for analysis tools to evaluate equipment, operational policy, and training within a system context. The IUSS is based on the philosophy of the Soldier as a System, equipment and other contributors to the soldier's performance considered as a synergistic whole. The IUSS methodologies simulate the Soldier System at multiple levels of interest, starting with the effects of equipment and battlefield stressors (e.g., chemical challenge and the subsequent burdens imposed by individual protection) on a taxonomy of human performance abilities and ultimately translating these effects to unit level measures of performance.
