Embedded training is a Key Performance Parameter of requirement for fielding FCS systems. Historically, system architectures as afterthoughts. Consequently, separate from the operational system and consume space design. For FCS, embedded training and operational concurrently. The Embedded Combined Arms Team Training Technology Objective (STO) is exploring a new embedded Objective System (OOS). OOS is being leveraged to provide and ancillary virtual vehicles (i.e. ground and air forces support. Early releases of OOS and the FCS System are being used to implement the architecture, and an is used as a testbed for its evaluation. This paper suggests future enhancements to the architecture.
