• Energy Strategy. The Army must focus on energy consuming systems as well as on energy supplying systems.

  • System Design for Efficiency. The Army must emphasize system integration at all levels so that the entire system can be optimized for energy efficiency. For example, modular hardware designs with dedicated processors are more energy-efficient than general-purpose computers. And communications architectures must be designed to distribute energy consuming components (sensors and processors) where they can most easily be served by local power sources.

  • Use of Commercial Technology. Army systems must be closely coupled to the technologies used in commercial products. The Army must be fully capable of incorporating the most recent data-processing and communications technology into its systems.

Recommendation 1b. The Army should accelerate the development and insertion of enhancements to the Land Warrior system, focusing on improvements to the computer/radio subsystem, because the estimated power requirements for communications and computing functions in Land Warrior are clearly excessive.

Recommendation 1c. The Army Acquisition Executive should make energy efficiency a priority consideration in evaluating contractor performance in future procurements of electronics for the dismounted soldier.

Recommendation 2a. To achieve energy sufficiency, the Army should set research objectives that focus on energy-efficient technologies. Energy efficiency is the key to success for the Army After Next.

Recommendation 2b. The Army should support use of computer-aided design tools for systems and integrated circuits specifically optimized for low power performance. If the necessary design tools are not available commercially, the Army should support its own development programs, perhaps in conjunction with related DARPA efforts. Army contractors for electronic systems should be required to use energy-optimizing design tools.

Recommendation 2c. The Army should support the development of mission-specific software for dismounted soldier systems. General-purpose software is wasteful and not energy-efficient.

Recommendation 2d. The Army should support the development and use of low power software, in which each instruction is written or compiled to minimize power requirements. New tools may be required for specific military applications.

Recommendation 2e. The Army should use dedicated electronic circuits wherever possible to minimize power requirements. Application-specific integrated circuit (ASIC) technology can achieve the efficiencies of custom circuits and hardware and still be cost effective.
