Given the challenges facing our Nation and allies from the Cyberspace domain, it has become an imperative to provide robust and appropriate representation of Cyberspace Electromagnetic Activities (CEMA) for use in the modeling and simulation (M&S) enterprise. Not surprisingly, achieving that imperative has resulted in the discovery of many gaps in CEMA M&S. There have been a few surprises over the past year that revealed new and unexpected vulnerabilities in the digital fabric of our commercial, industrial, and other sector infrastructures. The CEMA M&S Framework (CMFW) initiative (Vey, et al., 2019) provides a Models Based Systems Engineering (MBSE) approach to systematically survey the breadth of CEMA M&S. The CMFW is primarily focused on the needs of U.S. Army CEMA M&S. In 2021, the CMFW initiative aimed to incorporate Army modernization needs into the framework. To do this, we expanded the framework beyond its original foundation to include Use Cases and Mission-based Operational Threads representing critical process flows that correspond to new approaches being developed for the Army to address Multi-Domain Operations (MDO). The resulting framework can be used as a starting point for CEMA M&S representation for key Army systems to include artillery (Long Range Precision Fires), ground combat vehicles (Next Generation Combat Vehicles), aviation (Future Vertical Lift), as well as other priority areas. Our work provides a common model foundation for future CEMA M&S representation. This foundation does not dictate a single approach to all CEMA M&S problems but does provide a common reference for capability developers and commanders. Our approach strikes a balance between very high level “effects only” modeling and what might be considered a digital engineering (DE) representation to guide capability development for CEMA M&S.
