"Trainers for force on force training exercises at the Army's maneuver combat training centers and at home station are often distracted from coaching and mentoring responsibilities by the need to perform exercise control and feedback (OAF) functions. The fielding of new weapons and reconnaissance, surveillance, and target acquisition (RSTA) systems as part of force modernization will overwhelm trainers with new requirements unless improved concepts for tactical engagement simulation (TES) and instrumentation systems (IS) are implemented. This study produced an online database that was used to assess the benefits of implementing various new TES and IS concepts, or combinations of concepts, in terms of the number of OAF functions automated, the extent to which each function disrupts trainer coaching and mentoring activities, the number of gaps in training feedback addressed, and the number of systems to which each function or feedback gap applies. The TES and IS concepts we evaluated were designed to address the additional goal of avoiding the stove-pipe nature of past systems. The online database can be used to extent%mine the benefits of additional TES and IS concepts. The study sponsor is using the results to define requirements for future TES systems and IS for live training at CTCs and home stations."--DTIC.
