Various implementations of Live, Virtual, and Constructive (L-V-C) interactions have been demonstrated across numerous test and training ranges over the past few years. However, the virtual world remains largely disconnected from everyday live test and training activities. The Test and Training Enabling Architecture (TENA) standard being adopted by the soon to be fielded P5 Combat Training System and the next generation Enhanced Range Application Program presents a host of possibilities for standardized live virtual interactions. The Air Forces Combat Air Force (CAF) Distributed Mission Operations (DMO) Office, responsible for a distributed, interoperable, high fidelity, global training solution for virtual-constructive Mission Training Systems, is currently implementing a TENA interface as part of their DIS-HLA Portal solution. This TENA Portal has the potential to link the P5 CTS, EnRAP and DMT systems via a standard TENA interface.

This paper identifies, reviews, and analyzes the current DMO L-V-C effort and near term opportunities to provide live virtual interfaces between live P5 CTS and EnRAP systems and virtual CAF DMO systems utilizing the TENA standard. These interactions' would allow real-time live entities to be brought into the DMO virtual domain, and likewise, DMO entities brought into the live test and training domain. The interactions of live and virtual entities via TENA would be initially limited to audio, positional data, and weapons engagements; however, this level of interoperability represents a first step in realizing a standardized and affordable approach to achieving L-V-C test and training operations. This paper will also describe several efforts that would increase the fidelity of Live-Virtual interactions via a TENA standard interface.
