Chief of Army Staff General Dhiraj Seth on 15 July visited the headquarters of the XXXIII Corps — popularly known as the Trishakti Corps — at Sukna, West Bengal, reviewing operational preparedness along one of India's most strategically sensitive frontiers. The Corps, operating under the Eastern Command, is the primary formation responsible for guarding the China border in Sikkim.
What the Army Chief Reviewed
General Seth met senior commanders and received comprehensive briefings on operational deployments, evolving security dynamics, and ongoing technological advancement initiatives. According to an Army statement, the focus was on sharpening operational effectiveness and strengthening logistic capabilities across the Corps' area of responsibility.
The Army chief also interacted directly with personnel of the Indian Army and Central Armed Police Forces (CAPFs), commending their professionalism and commitment in what the Army described as 'some of the harshest terrain in the country.'
Jointness and Civil-Military Synergy Emphasised
General Seth highlighted the importance of seamless coordination among the forces deployed in the region. He underscored that jointness and military-civil fusion remain critical to navigating the complexities of the evolving security environment — a message that carries particular weight given the multi-agency nature of border management in the northeast.
The Trishakti Corps: Structure and Strategic Mandate
The Trishakti Corps comprises three mountain divisions deployed across the region. The 17th Mountain Division (Blackcat Division) is based in Gangtok, Sikkim; the 20th Mountain Division (Kirpan Division) is stationed in Binnaguri, North Bengal; and the 27th Mountain Division (Striking Lion Division) operates from Kalimpong, North Bengal.
Beyond its infantry strength, the Corps fields an artillery brigade, a Medium Range – Surface to Air Missile (MR-SAM) regiment, and an Army Aviation helicopter squadron based at Sevoke — a force mix designed for both high-altitude combat and rapid response.
Doklam and the Broader Security Context
Among the most critical areas under the Corps' watch is the Doklam trijunction — the point where India, Bhutan, and Tibet converge. It was here that a 73-day military stand-off between Indian Army troops and China's People's Liberation Army (PLA) unfolded in 2017, making it a perennial flashpoint in India-China relations.
This comes amid continued attention on the eastern sector following the Galwan Valley clash of 2020 and subsequent disengagement processes along the Line of Actual Control (LAC). The Trishakti Corps also shoulders responsibility for Humanitarian Aid and Disaster Relief (HADR) operations in the ecologically fragile state of Sikkim, which draws significant tourist footfall year-round.
What This Visit Signals
Senior command visits of this nature are standard practice but carry symbolic and operational weight, particularly when tensions along the LAC remain unresolved in certain sectors. The emphasis on technological upgrades and logistic strengthening suggests the Army is continuing its push to modernise high-altitude warfare capabilities. Further operational reviews across Eastern Command formations are expected as part of the Army's ongoing readiness cycle.
Point of View
A gap that has narrowed but not closed. What mainstream coverage tends to underplay is the HADR dimension: the same Corps that must deter a nuclear-armed neighbour also manages disaster response in an ecologically fragile Himalayan state increasingly battered by climate-linked events. That dual mandate — warfighting and humanitarian — makes the Trishakti Corps one of the most complex commands in the Indian Army, and General Seth's visit signals that both dimensions are being taken seriously.
