The drone war didn't start in Ukraine — and it won't end there

Every serious military on earth is now rewriting its training curriculum because of a seventy-dollar quadcopter. The first time a TB2 Bayraktar struck a Russian-made armour column in Nagorno-Karabakh in 2020, it was treated as a Turkish marketing demonstration. Five years later, the lesson is no longer debatable: the drone is not an adjunct to modern warfare. It is the defining instrument of it.

For the Indian Army, the question is no longer whether drones will decide future engagements along the LAC or LoC. The question is whether Indian soldiers at every echelon — from the platoon leader to the division commander — have the training hours needed to operate, defend against, and coordinate around them.

Four wars, one lesson

Four recent conflicts have each contributed a distinct tactical layer to what we now call the drone war.

Nagorno-Karabakh, 2020 — the ISR kill chain

Azerbaijan's use of Israeli Harop loitering munitions and Turkish TB2s demonstrated what happens when an adversary with inferior land forces achieves uncontested airspace at the tactical altitude. Armenian air defences, designed for fast jets, could not cue on slow, low, low-radar-cross-section airframes. Armour losses were catastrophic. The doctrinal takeaway was simple: if you cannot see them, you cannot shoot them, and if you cannot shoot them, you will lose your tanks.

Ukraine, 2022 – present — FPV at scale

The war in Ukraine has industrialised the first-person-view drone. Ukrainian and Russian forces now field tens of thousands of weaponised quadcopters monthly. FPV strikes account for a reported majority of contested-zone armour and personnel casualties in active sectors. Critically, the operator is a trained soldier — not a pilot — working out of a concealed bunker. The implication for Indian training is direct: drone piloting is an infantry skill, not an aviation skill.

Gaza, 2023 – present — counter-drone in urban terrain

IDF operations in Gaza have surfaced the counter-drone problem at urban scale: short detection windows, saturated RF environments, civilian-adjacent effectors. The doctrine that has emerged emphasises fused sensor pictures (radar, EO/IR, RF) with operators trained to classify in under five seconds. That is muscle memory. Muscle memory does not come from a PowerPoint.

The Red Sea, 2024 – present — the cost-exchange problem

Houthi anti-ship drones costing between $2,000 and $20,000 are being intercepted by SM-2 and SM-6 missiles at roughly $2 million each. Every tactical engagement the US Navy wins is a strategic engagement it loses. The training implication is that effector selection — when to use soft-kill, when to deploy kinetic, when to absorb — is itself a skill, and one that must be rehearsed.

If you cannot see them, you cannot shoot them. If you cannot shoot them, you will lose your tanks.

What this means for the Indian Army

The Indian Army is not a spectator. The LAC has seen Chinese surveillance drones since 2020. The LoC sees weaponised quadcopter drops from Pakistan-based handlers with monthly regularity. Myanmar's civil war has seen FPV adoption in Kachin and Arakan. The operational environment Indian soldiers deploy into already includes drones as a standing variable.

The training implication is threefold.

• Drone piloting must become an infantry-level skill, not confined to UAS units. Every section should have pilots. UDAAN-SIM exists for this reason — the physical RC controller is identical to the field kit, so muscle memory transfers without the cost and safety envelope of live flight.
• Counter-drone training must happen at the unit of engagement — the crew. A sensor operator, a command-and-control seat, and an effector operator must rehearse together, because the decisions they make are joint decisions. KAVACH-SIM models this crew-level fidelity.
• Electronic warfare literacy must move left of the battlefield. Operators trained in benign spectrum environments will fail their first GPS-denied mission. VAYU-SIM rehearses the transition from satellite navigation to inertial and visual SLAM under realistic jamming loads.

The choice is not whether, but how fast

Modern militaries do not have the luxury of waiting for the next procurement cycle to begin training. The drone war has already written its first three chapters. The Indian Army's syllabus has time to catch up to chapter four.

That catch-up happens either in simulation or in casualties. There is no third option.
