Armed forces from a multitude of nations and U.S. government agencies will come together next month for their annual examination of interoperability in a coalition environment. Although the focus will be on homeland defense and homeland security technologies, participants in the Coalition Warrior Interoperability Demonstration (CWID) also will scrutinize promising communications capabilities with broader missions in mind.

An inconspicuous reserve force is combating terrorism with the powerful weapons of experience and expertise. By combining knowledge gained in the areas of advanced technology with skills acquired through time in the field, these low-profile yet dynamic reservists are arming warfighters in current operations with new as well as improved capabilities. From work on undersea and aerial unmanned vehicles to biological threat detection on surface ships, this relatively small band of technology experts is pursuing a multitude of priority projects in nine focus areas.

The installation of a fiber optic network has vastly improved communications capabilities for troops fighting in Iraq. Military expertise, commercial technology, hard work and a bit of creativity have resulted in a reliable infrastructure that warfighters at all levels have come to depend on and expect. And, upgrades at command posts have freed up equipment that can be used at forward operating bases.

A rapidly evolving operational environment and new mission priorities are blurring the distinction between the U.S. National Guard, Reserve and active duty forces. As these units continue to operate together, efforts by the U.S. Congress and the U.S. Defense Department will further integrate the different branches of the military through a common payroll system and an occupational skills database.

As with the U.S. military, Canada is transforming its military to enhance network-centric operations and to improve information security. And, also similar to the United States, the Canadian Forces are counting on their reservists to shore up their ranks in current operations as well as in homeland security. Changes taking place today and plans for the future will align reservists better with their active duty counterparts and increase the expertise they bring to the battlespace. Communication reservists, who are already playing an active role, are likely to see their contributions to national security expand in the near future.

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.

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.

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).

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.

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.
