The Army needs the ability to characterize the effectiveness of test and live training systems to improve realistic training and real-time arbitration of casualties. For years, the Army testing and live training communities have strived to develop a robust Real Time Casualty Assessment (RTCA) capability. Currently, both communities are working closely to develop the ability to characterize the degree to which specific, identified capability upgrades to test and live training systems could improve RTCA. This project leveraged a capabilities based assessment method developed for the USMC Squad Immersive Training Environment (previously published as an I/ITSEC paper- Johnston, Dunfee, et al., 2012). This paper describes the methods and findings of the Systematic Team Assessment of Readiness Training (START) method as it was applied to a use-case of the Bradley Fighting Vehicle (BFV) crew training. A baseline capability assessment of the live training environment for the BFV is described in terms of its ability to support effective live Force-on-Force (FoF) training and RTCA. We describe how the START method was employed to establish environmental attribute (e.g., battlefield effects) capability gaps that are used to prioritize investments in test and live training systems based on the degree to which the investments could improve training and RTCA effectiveness. Using the methodology, quantitative and qualitative data on current testing and training capability was collected. The results of this data collection will be presented in this paper. This is a collaborative effort among the Program Executive Office for Simulation, Training, and Instrumentation (PEO STRI), the Army Test and Evaluation T&E Command, the Naval Air Warfare Center Training Systems Division (NAWCTSD), and the US Army Research Laboratory Human Research and Engineering Directorate (ARL-HRED).
