The high rate of non-medical Soldiers (Combat Lifesavers and self-aid/buddy-aid) performing field care necessitates additional medical training for those Warfighters.Unfortunately, most non-medical personnel are not provided with opportunities to practice medical skills in a high stress environment prior to completing them during live missions due to a lack of access to ruggedized high fidelity training platforms that can be used in a live training environment.To meet this training gap and provide a low-cost and flexible training tool that allows all Warfighters to practice first response medical skills during high stress force-on-force training exercises, the Modular Multimodal Casualty State and Care (M2CSC) Toolkit will be designed and developed.The proposed platform will present simulated multimodal casualty state cues allowing medical care learners to interact with patients and respond to them as they would in the real world.The design of the proposed system will be driven by a task analysis, cue fidelity evaluation, and training needs analysis.Upon defining the training gap, a technology analysis will be conducted and used to drive the development of a modular framework. Proof of concept demonstrations will be developed to support early commercialization and iterative design meetings with key stakeholders and transition groups.
