Soldiers in the Iraqi theater are receiving medical care from doctors thousands of miles away through telehealth programs and the use of the Internet and servers. Physicians using this capability can provide better continuity of care and better medical access, as well as reduce loss of duty time for soldiers deployed in Iraq. In addition, the telemedicine systems implemented in Iraq throughout 2004 and into 2005 have aided not only the soldiers receiving the care but also the doctors providing it. The technology not only keeps them safe from traveling through hostile environments but also allows more collaboration between other doctors in theater.

On the battlefield of the future, a U.S. Army soldier is hit by shrapnel from an artillery round and is rendered unconscious with internal injuries to his torso. He is alone and no one witnesses his injury, but the intelligent agents in his automated self-monitoring system detect that he is in crisis, and the system transmits a signal to a regional command center. Officers at the command center dispatch an unmanned rescue vehicle, which enters the live-fire zone and deploys small robots to collect him carefully for removal from the hot zone.

Combatants in the war on terrorism come in all shapes and sizes, including some that are nuts and bolts, metal and machinery. In operations in both Afghanistan and Iraq, warfighters count not only on their buddies to keep them safe but also on luggage-size robots that help clear the improvised explosive devices being used so incessantly by insurgents. Using manportable mechanical marvels, explosive ordnance disposal teams can disarm or detonate explosives from a distance, keeping team members out of harm's way while clearing the way for troop movement.

With updated cabling and server farms in place, the U.S. Navy is making way on a government-owned, government-operated information technology initiative that ultimately will affect more than 41,000 users in Europe, the Middle East and the Far East. During the coming months, sailors stationed at bases outside the continental United States, beyond the scope of the Navy/Marine Corps Intranet, will be coming aboard their own enterprisewide network.

A communications interface system soon may enhance the situational awareness and connectivity of U.S. Marine Corps units. The equipment consists of vehicle-mounted racks housing an interchangeable set of tactical radios, routers and configuration software that allows commanders to quickly select, change and modify their tactical data networks for specific missions. By linking a variety of radio systems into a single network, the technology permits units with previously incompatible radio systems to communicate with each other.

Setting up and maintaining a communications network in a war zone is difficult under any circumstances, but it is especially complicated in a battlespace without defined front lines. To meet this challenge, the U.S. Army is combining military systems and commercial solutions to establish a reliable network for commanders and warfighters in operation Iraqi Freedom.

Feedback from ongoing U.S. military operations in Southwest Asia is enhancing a key fire control and battle management system. Designed to help track friendly units and direct available artillery and air platforms against enemy forces, this software-based application is an important command and control asset and a major component for upcoming programs such as the U.S. Army's Future Combat Systems (FCS).

Disposable sensors, a single radar set that performs several tasks and electrical power devices that refuel from a diesel truck's gas tank are just some of the innovations that may reshape U.S. Army operations on the battlefield of the future. This research is altering the vision of the transformational force even as ongoing programs pick up speed, and it promises new and exciting capabilities to further extend the Army's battlefield supremacy.

The U.S. Army is tasked with a three-sided challenge as it seeks to transform its communications-electronics systems. The Army must continue to progress with far-reaching plans that will change the way it conducts military operations; it must respond to warfighters' urgent information technology needs in Afghanistan and Iraq; and it must incorporate changes inspired by lessons learned in those wars into its long-range efforts.

There appears to be no speed limit for the changes taking place in the military as it enters a new millennium facing operations that involve coalition partners and diversified threats. Leaders look to industry to help with the transition to the latest paradigm, where issues such as bandwidth, information assurance and interoperability are as important as training, tactics and tanks.
