Electronic warfare (EW)
Military operations using the electromagnetic spectrum — to detect, exploit, deceive or deny an adversary's use of it.
Electronic warfare is the discipline of military operations conducted in the electromagnetic spectrum. The classical taxonomy divides EW into three branches: electronic support (passive listening to enemy emissions), electronic attack (actively jamming, deceiving or destroying enemy systems), and electronic protection (hardening one's own systems against adversary EW).
EW has moved from a specialist arm to a foundational layer of modern combat. Every drone operation is an EW operation, every counter-drone engagement is an EW engagement, every contested radio link is an EW problem. Russian systems like Krasukha and Silok, Chinese EW regiments along the LAC and Turkish Koral systems in Pakistani service together establish that the electromagnetic spectrum will not cooperate in any zone worth flying into.
For Indian Army training doctrine, the implication is that EW literacy is no longer a specialist skill. Every drone pilot, every counter-UAS operator, every infantry small-unit leader operating with attached UAS must understand how the spectrum will fail and how to operate when it does. Synthetic environments are the only way to scale that literacy at the rate the operational tempo now demands.
