For the past six years embedded simulation research has focused on methods to transform digital-based current force systems, such as the latest version of Abrams tank and Bradley Fighting Vehicle, into systems capable of supporting embedded individual, crew and unit training. This research was spearheaded by the Inter-Vehicle Embedded Simulation Technology (INVEST) Science and Technology Objective (STO). While many technologies still required improvement to meet onboard training needs and size limitations, the INVEST program had great success in demonstrating the potential of the technology for both current and future programs. Based in part on the success of the INVEST program, the Army decided in 2003 to make fully embedded simulation a requirement for Future Combat System (FCS). This paper discusses research focused on embedded simulation capabilities for the FCS.

The Embedded Combined Arms Team Training and Mission Rehearsal (ECATT/MR) STO was initiated in FY03 to explore risk areas for FCS embedded simulation. As a new system start, FCS has the advantage of building embedded technology into the fundamental architecture of the system rather than having to add it later to a fielded system. However, development is complicated by the fact that neither the FCS vehicles nor FCS doctrine are yet defined. This paper discusses the development and application of an embedded testbed as an aid to FCS embedded training concept exploration. The paper discusses testbed use to define a fundamental embedded interface that will permit embedded components to interoperate via a network for large exercises and mission rehearsal. Other technologies being explored for FCS are also discussed such as the vehicle-soldier linkage for dismounted infantry training, intelligent tutoring and the use of C4ISR to control computer generated forces. The paper concludes with a discussion of future work.
