Computer-based instruction – a proven approach – must adapt to fulfill the growing needs of military and interagency training. This future vision requires innovative toolsets to help bridge the gap between academic, individual instruction and large-scale, mission rehearsals. Given the constrained training budgets of today and tomorrow, one must innovate to enable team training. This paper provides analysis for the existing military training structure and offers insights into how it can be adapted to be lightweight, agile, and more cost efficient at training small teams in preparation for existing large scale exercises. This approach fosters mastery by providing the training audience autonomy of time and team – enabling small team training at a time and place of their choosing. Our innovation’s simplicity has demonstrated the powerful capability of a distributed and immersive application. The paper closes with lessons learned gathered from exercises conducted between 2010 through the present.
