Why the tank still matters in a drone-dominated battlefield

Question (10 marks, ~150 words):

Drones and precision weapons have transformed the battlefield, yet the battle tank remains indispensable. Critically analyse in the context of India's induction of the indigenous Zorawar light tank.

Introduction: The Russia-Ukraine war, where cheap loitering drones destroyed multi-crore tanks on a transparent, surveilled battlefield, revived the claim that the battle tank is obsolete. The question demands a balanced verdict, read through India's induction of the indigenous Zorawar light tank.

Arguments for obsolescence:

• The critics have a point: cheap drones impose disproportionate costs on armoured forces.
• On open, drone-saturated plains massed tanks are exposed to aerial surveillance and precision strikes.

Why the tank endures:

• Drones and missiles can damage assets but cannot enforce surrender or occupy ground; only ground forces hold captured territory, as 1965 and 1971 showed.
• In the high Himalayas, altitude, narrow valleys and weak bridges make armoured mobility the decisive edge.
• China's PLA has already deployed Type-15 light tanks along the LAC, an operational gap the 25-tonne, air-transportable Zorawar, jointly built by DRDO and L&T Defence, directly narrows.
• India plans 354 Zorawars for about Rs 17,500 crore, inducting them in 2028-29 alongside its T-72 Ajeya fleet (~2,400-2,500) and T-90S Bhishma (1,200+).
• Modern add-ons, anti-drone protection, jammers and hard-kill active protection systems, keep tanks survivable within a combined-arms doctrine.

Way forward:

• The way forward is to adapt armour, not abandon it.

Conclusion: The tank is no longer the undisputed king, but as an indispensable component of integrated air-land defence, it is far from disappearing.
