Recent discussions emphasize the critical role of passive RF sensors in enhancing the autonomy and effectiveness of small infantry teams in contested electromagnetic environments. These sensors enable units to achieve situational awareness, allowing them to detect enemy emissions and adjust tactics independently, even when conventional communication lines are compromised. The ability to geolocate enemy signals transforms SIGINT into actionable intelligence, streamlining the sensor-to-shooter cycle and facilitating rapid response. As global militaries, including NATO, increasingly invest in electronic warfare capabilities, the integration of passive RF sensing into tactical operations is emerging as essential for maintaining decision superiority and operational security, ultimately shaping the future of modern warfare.
