The debates over information operations have shifted from academia and Pentagon studies, military exercises and computer simulations to joint warfare over the sands of Iraq. This is the first opportunity to document and evaluate the role information actually plays in evolving military transformation into truly joint operations.

Information operations are coming of age, moving through the exploration stage of adolescence and forward toward a future that some experts believe should feature ubiquitous integration. Although computer systems have already proved their ability to influence the nature of warfare, the maturation of doctrine and technologies is likely to bring with it even more substantial changes in the way the military conducts operations.

The U.S. Defense Department is introducing a new tool to protect military installations by transforming force-protection information sharing from a hierarchical, service-centric model to a network-centric model. The system will allow subscribers to have a common awareness of all suspicious events that are taking place in their vicinity.

Sky marshals, metal detectors and multiple identification checks may increase security in the corporeal world, but guarding the nation's information superhighway requires different tactics. And in the information age, homeland security must extend into the digital realm, or even a tiny crack could allow adversaries into some of the most important systems in the world today.

The battlespace network trialed in the woods of Kentucky and grown from the sands of Kuwait provided the necessary connectivity for the U.S. Army's 101st Airborne Division (Air Assault) to strike deep into Iraq. Not all of the assets assembled and deployed by the division's 501st Signal Battalion were exploited to their fullest, and some proved more important than originally envisioned. Yet, the network linked the air assault division as its location and mission changed with the flow of battle.

The deep thrust into Iraq by the U.S. Army's 101st Airborne Division in operation Iraqi Freedom was enabled as much by kilobytes as by helicopters. An advanced command, control and communications architecture allowed the geographically dispersed mobile forces to remain in contact with their individual commanders as well as with the division headquarters.

Last year, I discussed in my commentary how information must be available-as freely as oxygen in the air-to virtually everyone. In presenting this point of view, I offered that power lies in how one uses information.

The newest U.S. combatant command, tasked with defending the homeland, is taking a military approach to using civilian assets. This does not involve discarding existing U.S. laws that mandate separation of military activity from local responsibilities. Rather, it involves organizing and coordinating threat protection and emergency response efforts to maximize available federal, state and local government resources. And, it may include placing the military command under civilian leadership.

The newly independent U.S. Air Force Space Command is focusing on integrating exo-atmospheric operations with lower altitude activities, including ground campaigns. These operations in space, which range from communications to precision guiding of munitions, are becoming less of a separate warfighting aspect and more of a united element of high-technology network-centric warfare.

While military combatants continue to fight the war against terrorism on the battlefield, U.S. government officials are stepping up work to protect the borders of cyberspace. Information infrastructure security is such a high priority that government agencies are now required to provide reports on risk assessments, system security needs and security plans before they receive program funding.
