Advanced Survivability Systems will be fully utilized by the Soldiers in the battlefield when the spatial, power and data integration issues are effectively managed during the vehicle integration process. Challenges faced during the integration process range from the packaging of oversized legacy equipment to the environmental requirements of advanced sensory systems. This paper discusses such integration efforts and the lessons accumulated during this resource intensive process. The utility of this complex integrated system was tested and validated by the Soldiers recently returning from the theater. Some surprising aspects of the testing resulted in questioning our traditional view of information presentation to the Soldier.
