India begins major tri-Service drill along western border with Pakistan

A major tri-Service military exercise, ‘Trishul’, kicked off on Thursday (October 30, 2025) along the western border with Pakistan, showcasing the joint operational capability and strategic preparedness of the Indian Army, Navy, and the Air Force.

The large-scale drills, being conducted from October 30 to November 10, span across Gujarat and Rajasthan, and are aimed at enhancing interoperability, coordination, and mission readiness among the three Services.

The Navy is leading the opening phase of the exercise, followed by the Army in the second phase and the Indian Air Force in the concluding phase. The Border Security Force and the Coast Guard are also participating as auxiliary forces, underscoring the integrated approach to national security.

More than 20,000 troops, supported by T-90S and Arjun tanks, attack helicopters, missile systems, Rafale and Sukhoi-30MKI fighters, as well as a fleet of frigates and destroyers, are conducting joint operations along the western front.

A senior defence official informed that the Trishul exercise highlights India’s growing focus on joint planning, integrated command structures, and combat readiness to address evolving security challenges.

Notably, ahead of the commencement of the exercise, Pakistan announced changes in certain flight routes for the Karachi and Lahore regions.

Earlier this month, on October 2, Defence Minister Rajnath Singh cautioned Pakistan, stating that “a route to Karachi passes through Sir Creek.” He warned that any aggression in the Sir Creek area would be met with “a resounding response that will change both history and geography.”
