Soldier systems rely on technological advances to make electronics and electro-optics small, lightweight, and power-efficient

Technology focus -- Technologies for the warfighter must run a cruel gauntlet of size, weight, and power consumption, as well as enhanced capability and affordability, before they can take their places alongside the most promising network-centric systems on the digital battlefield. For the boots-on-the-ground combat soldier, size and weight is everything. Each combat soldier can carry only a finite amount of gear into battle -- loads that often approach 100 pounds per warfighter. This means he and his commanders need to strike the right balance of weapons, sensors, communications, food, water, and survival equipment to give him the best chance of achieving the mission and getting back alive.
