In this in-depth interview, Colonel Rómulo García offers a frontline commander’s perspective on how unmanned aerial systems, loitering munitions, and low-cost saturation attacks are reshaping modern warfare. Drawing on operational deployments, multinational штаб experience, and Spain’s evolving doctrine, he outlines why counter-UAS must now be treated as a joint, multi-domain, and fully integrated capability within NATO IAMD architectures. From layered defence networks and sensor-to-shooter timelines to the balance of kinetic and non-kinetic effects in congested environments, this discussion captures the real-world challenges shaping air defence today.
