The combination of a low-tech platform and a high-tech radio is extending beyond-line-of-sight communications from 10 miles to more than 400 miles. The approach employs small hydrogen balloons that are sent into the near-space realm-defined as from 65,000 feet to 325,000 feet above Earth-toting two AN/PRC-148 radios that relay ground-to-ground, air-to-ground and ground-to-air voice and data communications. Although the capability was developed to address a combat-mission need statement and is scheduled to be deployed to theaters of operation in December, the benefits of this technique also could extend to homeland security as well as emergency relief efforts such as assistance in the aftermath of Hurricane Katrina.

If actions speak louder than words, then current military operations are shouting volumes about the benefits of network centricity in warfare. Case studies sponsored by the U.S. Defense Department's Office of Force Transformation present an abundance of hard evidence that networked forces can be up to 10 times more effective than non-networked troops in high-intensity conflict missions. In comparison to voice-only communications, what experts call the "information position" is between 10 and 100 times better not only for commanders but also for the individual warfighter. The studies also point out that even less-than-perfect networks can be valuable.

As NATO shifts from a defensive alliance to a more responsive multinational organization, it is developing technologies and doctrines that provide commanders greater control over their assets. Key to this effort is a suite of systems that allows NATO commanders to establish logistics bases quickly to support a mission while minimizing its supply footprint.

The fusion of satellite communication, global positioning system and radio frequency identification tag technologies is giving the U.S. Marine Corps the ability to monitor the status of fallen comrades and battlefield assets. The Marines have several technology experiments underway that test the military's In-Transit Visibility/Total Asset Visibility concept, which seeks to identify, locate and monitor personnel, equipment and supplies from origination to destination. As the defense community grapples with how to assess and implement the capabilities these evolving technologies generate, field tests indicate they will improve situational awareness while saving time, money, resources and lives.

A successful future U.S. Air Force tactical operation may end with both a bang and a whimper. Traditional munitions-based operations employing kinetic weapons increasingly are sharing the airspace with information-based nonkinetic measures. The result soon may be an air strike that neutralizes an adversary with only minor damage, if any, to enemy assets.

U.S. Army tank commanders now are looking up at information the same way fighter pilots do: through a helmet-mounted ocular. The head-up device allows tank crew members situated outside of the hatch to view the same information that is displayed on computers inside the tank. The equipment was introduced with troops in operation Iraqi Freedom.

Even the most vocal advocates of Bowman would accept that the program's lengthy history has led it to become a synonym for procurement delay. Nonetheless, Bowman's in-service date was declared in March when the first unit, the British Army's 12 Mechanized Brigade, successfully completed a formation-level operational field trial using two mechanized battle groups and a brigade headquarters.

Construction of a new tactical communications infrastructure is underway in Iraq that will support tens of thousands of troops and eventually benefit the Iraqi people as it is turned over for their use when the U.S. military leaves the country. With the help of commercial capabilities and industry expertise, the infrastructure will improve tactical operation coordination between multiple sites by increasing the speed at which information can be shared from kilobytes to megabytes.

Military leaders are developing a vision of the tactical operations future where adversaries will have to decide if they should send flesh and blood troops to fight nuts, bolts, circuits and sensors. The implications of this battlefield revolution are far-reaching, and initial technical capabilities exist today. Military experts agree that it is only a matter of time before nations send sophisticated machines to augment well-trained troops. They also assert that it is in the United States' best interest to be the leader in this inevitable transformation of combat.

A major U.S. Defense Department research program is developing lightweight, miniaturized, low-power radios for dismounted infantry and support equipment. The program, which is part of an initiative to replace the current generation of military radios, has drawn competing design teams from across the defense industry. Interoperability is a key issue in the move toward advanced software definable radio systems. Lessons learned from operation Desert Storm indicated a need for greater communications between the services during combat, necessitating the development of radios sharing common waveforms usable by all the services and that can be rapidly reprogrammed in the field.
