In areas lacking trustworthy communications infrastructure, deployed servicemembers rely on wireless devices to perform double duty: they not only provide access to the network; they are the network. Protocols for these networks require nodes to coordinate among themselves to manage resources, such as spectrum and power, and determine the best configurations to enable sharing of information. A problem with these protocols is that they implicitly trust all information shared about the security and operational state of each node, and the network as a whole. Consequently, inaccurate control or security information can quickly render the network unusable. This shortcoming could put productivity and mission success at risk as use of military wireless systems increases.
Warfighters in aircraft, on ships and in ground vehicles have benefited tremendously from technological advances in recent decades, with advanced capabilities ranging from real-time situational awareness to precision armaments. But many of these benefits depend on equipment with substantial size, weight and power requirements, and so have remained unavailable to dismounted infantry squads who must carry all their equipment themselves.
State-of-the-art military sensors today rely on “active electronics” to detect vibration, light, sound or other signals. That means they constantly consume power, with much of that power and time spent processing what often turns out to be irrelevant data. This power consumption limits sensors’ useful lifetimes to a few weeks or months when operating from state-of-the-art batteries, and has slowed the development of new sensor technologies and capabilities. Moreover, the chronic need to redeploy power-depleted sensors is not only costly and time-consuming but also increases warfighter exposure to danger.
To succeed in their missions, military units must have a robust, multi-faceted picture of their operational environments, including the location, nature and activity of both threats and allied forces around them. Technology is making this kind of rich, real-time situational awareness increasingly available to airborne and other vehicle-assigned forces, along with a capacity to deploy precision armaments more safely, quickly and effectively. Dismounted infantry squads, however, have so far been unable to take full advantage of some of these highly effective capabilities because many of the technologies underlying them are too heavy and cumbersome for individual Soldiers and Marines to carry or too difficult to use under demanding field conditions.
Modern military engagements increasingly take place in complex and uncertain battlefield conditions where attacks can come from multiple directions at once, and in the electromagnetic spectrum and cyber domains as well. U.S. Army and U.S. Marine Corps dismounted infantry squads, however, have been unable to take full advantage of some highly effective multi-domain defensive and offensive capabilities that vehicle-assigned forces currently enjoy—in large part because many of the relevant technologies are too heavy and cumbersome for individual Soldiers and Marines to carry or too difficult to use under demanding field conditions.
