Protection of the Global Information Grid now has evolved into global asymmetric warfare. Engaging in this combat is the principal mission of the U.S. Cyber Command because the infrastructure of the Internet is fundamentally insecure, and the U.S. Defense Department depends increasingly on this cyber highway to function. There are tens of thousands of defenders of the Internet infrastructure who must be vigilant around the clock, everywhere. Meanwhile, small teams of attackers can strike undetected whenever they choose, from wherever they may be in the world. This is why the contests between the defenders and the aggressors meet the definition of asymmetric warfare in its extreme form.

Upgrades to a major command and control system soon will provide U.S. commanders with better tools to coordinate theater- and strategic-level operations.

A small business innovation research project is taking the Joint Tactical Radio System Ground Mobile Radio program from simulation to emulation through a combination of technical advancements and government cooperation. The effort would enable the military to scale up the radio network and ensure the system will work without investing in actual hardware. Training options also exist as part of the future employment of the technology.

The U.S. Defense Department is taking significant strides toward resolving problems with information technology acquisition in part because of impetus from outside parties. Reports by an independent board and pending legislation have made specific recommendations for changes in the procurement process that the department is working to implement.

The U.S. Army recently finished construction of an optical network that offers troops in certain foreign locations all the data transmission speed and availability they need for the foreseeable future. After Defense Communications Systems–Europe completed the development process earlier this year, the 5th Signal Command took over control of the network and is studying how best to migrate from asynchronous transfer mode legacy systems to the new one.

Joint-service weapons intelligence teams around Iraq are deriving insights about enemies’ use of weapons in the country. The work helps coalition forces alter their operations and tactics to better avoid prevalent dangers. The knowledge of perpetrators’ methods and identities aids in the fight against various weapons, especially improvised explosive devices. Team members processing sites collect information about explosives, then report on their findings, adding to intelligence databases and troop knowledge.

The U.S. Navy is outfitting its ships with unclassified wireless networks that will allow sailors and marines to move around a vessel with laptops and personal digital assistants.

A new radio undergoing trials with the U.S. military soon may allow joint and coalition warfighters’ legacy radios to interoperate without the need for human-directed spectrum management. The radio combines several technologies that allow it to serve as a gateway linking disparate radios and datalinks together into a digital network. The radio is able to avoid the interference and disruptions common to wireless communications in tactical battlefield environments.

The U.S. military and industry are developing a handheld device that will provide warfighters in the battlespace the same capabilities that are the lifeblood of most teenagers in developed countries: texting, data, voice and video-on-demand in the palms of their hands. Creating this information-sharing phenomenon takes more than just handing iPhones out to soldiers, sailors, airmen and Marines. Because warfighters often operate in places with less-than-ideal infrastructure and need secure channels, delivering these Swiss Army knives of communications gadgets requires stratospheric support.

Energy as a weapon and an enabler could dominate future battlefields, according to a recent war game that focused on military energy requirements. Participants in the 2009 war game, which had the theme “Future Energy Requirement on the Battlefield,” examined energy produced, packaged and used in novel ways to enable persistence.
