Prior paradigms for Marine Corps training are established in the context of live, virtual and constructive domains. The objective of this paper is to introduce a new agenda for discussion of training in the domain of mixed reality (MR). Research, experimentation, and prototype demonstration currently underway provides growing understanding of MR experiences; showing how augmented reality (AR) and augmented virtuality (AV) extend real world presence. Alone; however, they do not fulfill the understanding of analysis, preparation or planning for training necessary to achieve authentic, meaningful, and simultaneous immersion for a Company of Marines operating in the synchronized manner to be achieved by Enhanced Company Operations.

The Marine Corps is drawing on lessons from traditional training systems and capabilities through the Squad Immersive Training Environment (SITE) Initial Capabilities Document (ICD), the DoD Future Immersive Training Environment (FITE) Joint Capability Technology Demonstration (JCTD), and expanded employment of its Infantry Immersion Trainers (IIT) to define the capabilities, methods, and resources necessary to accomplish MR domain training. This paper proposes a roadmap to support the development of immersive training systems all the way up to a Company of Marines conducting Enhanced Company Operations.
