(See the section "Commercial Trends" in Chapter 5.) In fact, the energy efficiency Laser designators represent a unique power demand that of the best-performing processors has begun to decline as can be many times greater than that of other electronics for they move into a power-limited operating regime.

Even this relagreater than the power required for other functions of the tively low power level may require a separate power source, dismounted soldier. Because of these excessive power in addition to those sources envisioned for the other soldier requirements, microclimate cooling for the OFW will be electronics.

The vision is to utilize strain product capabilities versus their frequency response such devices with power supplies that are energetically capabilities. autonomous of other power sources.

The DARPA program manager indicated that the concluded that hybrid power and energy sources, generally a size, weight, and inertial characteristics of electrical actuators high specific battery combined with an electrochemical that would be needed to provide equivalent energy levels for capacitor, offset many of the problems of high-maintenance these devices would be too great. If one reviews the hydraulic systems.

An important major lesson that has been learned in Perhaps the clearest indication that graceful degradation Operation Iraqi Freedom is that just-in-time logistics is needed is the desire expressed by soldiers that individual resupply may not be able to keep up with the rapid tempo of weapons have a separate power source rather than being military operations.
