Neutralising an individual drone follows a fixed chain: Detect → Track → Identify → Decide → Defeat → Assess. See the reference card Counter-UAS Kill Chain and the interactive diagram in Chapter 10.2.
Note
Radar alone is often insufficient: the small radar cross-section and low altitude of FPVs and Shaheds regularly keep them below the effective detection threshold. This is precisely the gap that additional sensors (RF, EO/IR, acoustic) must close.
