For decades, India’s Siliguri Corridor — the narrow strip of land linking the mainland with the Northeast — sat somewhere between strategic concern and bureaucratic footnote in policy circles. Today, it is unmistakably centre stage in India’s defence and infrastructure planning. The transformation in how New Delhi perceives and projects security around the so-called “Chicken’s Neck” is not cosmetic. It is a response to tangible developments that make complacency dangerous.
The biggest signal of this shift is the recent establishment of three new military installations along the corridor’s eastern flank near the Bangladesh border — at Lachit Borphukan Military Station in Dhubri (Assam), and forward bases in Kishanganj (Bihar) and Chopra (West Bengal). These are not token outposts; they are equipped for rapid deployment, intelligence coordination and force projection, tightening India’s grip on one of its most sensitive choke points.
This build-up is a clear acknowledgement that the corridor’s defence can no longer be taken for granted. The corridors of power in Dhaka are shifting. The interim leadership in Bangladesh has signalled a foreign policy pivot, engaging more closely with China and Pakistan’s military establishment. Defence procurements and joint ventures discussed with Beijing underscore Dhaka’s evolving security orientation. In a neighbourhood where alignments matter, such shifts complicate India’s strategic calculus around its eastern periphery.
Beyond troop deployments, India has layered integrated air defence systems into the Siliguri equation. Russian-made S-400 long-range surface-to-air missiles, deployed to provide a protective umbrella over the corridor, represent a qualitative leap in airspace denial capabilities. Simultaneously, fighter squadrons, including Rafale jets at Hashimara Airbase, and supersonic cruise missile regiments provide both deterrence and deep-strike options.
The urgency is not unfounded. Geography has always been unforgiving here: barely two dozen kilometres of land, squeezed between Nepal, Bhutan, Bangladesh and close to China’s presence in the Himalayas, is all that stands between the vast Northeast and the rest of India. A disruption — be it military, hybrid or logistical — could isolate millions, sever supply lines and force New Delhi into reactive postures.
But the challenge is not solely military. India has moved on the infrastructure front too. The Cabinet has approved major rail expansion near the corridor to increase redundancy and capacity, a crucial step to ensure that national integration and economic flows are not hostage to a single narrow route. Plans to revive abandoned airstrips from the World War-II era across Bengal, Assam and Tripura reflect the same principle: disperse and deepen access nodes to blunt any attempt to choke connectivity.
These moves reflect strategic realism as much as they signify deterrence. Guarding the corridor is not just about keeping adversaries at bay. It is about signalling resolve to partners and neighbours that India’s Northeast is integral to the nation’s unity and future. It also recognises that security cannot be achieved by military hardware alone; infrastructure, diplomacy and political coherence matter just as much.
What remains critical now is policy follow-through. New bases and systems are only as effective as the doctrines that govern them. India must ensure that defence planning is synchronised with diplomatic outreach — particularly in managing ties with Bangladesh — and with economic initiatives that knit the Northeast more tightly with the mainland. The Chicken’s Neck will always be narrow. What must widen is India’s margin for strategic action. In a shifting regional environment, treating that corridor as anything less than a priority would be a strategic error India can afford neither politically nor militarily.
