 JTRS closely integrates with target designators that plug into it, so that a separate radio is not required to communicate with precision-guided munition launchers.While unmanned aerial vehicles obviously involve more technologies than electronics, the availability of man-portable UAVs for launch by the patrol, as well as communications between the patrol and a high-performance UAV, may result in fundamentally new tactical doctrines.Software defined radio, along with standard information exchange protocols such as JTIDS Link 16, are enabling appropriate communications and situation awareness, reducing the chance of fratricide, across multiple military services.
