The document proposes a future warrior weapon fighting system concept to increase combat lethality through an integrated systems approach. It involves designing weapons, sights, ammunition, targets, ranges, testing, and training as an interdependent system. Key elements include developing weapons as local area networks, tailoring the force mix to specific missions and terrain, and implementing team-based high-fidelity training and qualification to better prepare soldiers for combat performance under stress conditions. The goal is to increase soldiers' and units' combat lethality while decreasing fratricide and accidental discharges through a total systems design that considers human factors.
