As part of Canada’s larger soldier system modernization programme, the Soldier Information REQuirements Technology Demonstration (SIREQ TD) project aims to define and empirically validate the performance requirements for the future Soldier System by demonstrating capability enhancements in command execution, target acquisition, and situation awareness for the individual dismounted soldier in 2010-2015. Given the potentially limitless scope for investigating dismounted infantry information modernization requirements, a modified cognitive task analysis (CTA) approach was chosen to investigate, identify, and characterize the critical information requirements of dismounted infantry soldiers in a range of representative operational scenarios. Beyond the traditional knowledge audit stage, additional analyses were developed to further characterize the cognitive task demands in an operational context and to better delimit the scope of future SIREQ TD experimentation (i.e. information indices, information elements, and attentional demands analyses). The results of the CTA analyses indicated considerable scope for improving information-related tasks at both the individual and group levels for both the rifleman and section commander roles. The CTA revealed that the core capabilities of sensing, terrain visualization and information exchange are critical to all soldier activities and thus emphasized that technology incorporation at the individual and team levels could prove to be very
