This report summarizes work performed during a quick-response analytic effort in support of the 2001 Army Science Board (ASB) Summer Study on Objective Force Soldier, along with subsequent efforts in related areas. The work used high-resolution constructive simulation to examine key aspects of “objective soldier,” with the modeling taking place in the 2015–2020 time frame. In conducting the study, the research team interacted with various members of the ASB and, in particular, with key members of the Analysis, Fightability, and Concepts panels, drawing extensively on their forwardlooking ideas and ultimately integrating many of these ideas into the research. The primary.
