The Indian Armed Forces are currently conducting a large-scale joint exercise called Trishul from October 30 to November 10, 2025, along the country’s western border with Pakistan. This major military event involves the Army, Navy, and Air Force, all working together to practice coordinated operations on land, sea, and air. The focus area of the exercise is Sir Creek, a sensitive border region between India and Pakistan.
Officials and defence experts say Trishul is not a routine training exercise—it is a strategic message to Pakistan and the terror groups that operate from its soil. It shows India’s readiness and strength, as well as its ability to respond quickly and decisively to any threat.
The roots of this exercise go back to Operation Sindoor, which took place in May 2025. This operation was launched after a major terror attack in Pahalgam on April 22, in which several Indian soldiers lost their lives. In response, India’s Armed Forces carried out coordinated precision strikes across the border to destroy terrorist camps and their support systems inside Pakistan and Pakistan-occupied Kashmir (PoK).
Operation Sindoor was carefully planned and executed within a short time frame. It was meant to send a message that India will not tolerate terrorism and is capable of taking swift, targeted action. Government reports and official statements described it as a limited but powerful operation that destroyed terror infrastructure while avoiding unnecessary escalation.
The success of Operation Sindoor encouraged India to think differently about defence. Military analysts and policymakers began referring to this change as the “Post-Sindoor Doctrine.” This new approach focuses on prevention, coordination, and speed rather than waiting to react after an attack. It also underlines the importance of all three services—Army, Navy, and Air Force—working as one unit.

The Post-Sindoor Doctrine represents a major shift in India’s defence thinking—from reactive defence to proactive deterrence. Instead of waiting for enemies to act, India now focuses on identifying and neutralising threats before they reach Indian territory. This strategy also involves multi-domain cooperation, meaning that land, sea, air, cyber, and space operations are all coordinated under one command.
Exercise Trishul is the first large-scale demonstration of this new doctrine. It allows the Armed Forces to test how well they can operate together under real-world conditions. The exercise includes:
Joint air-land-sea operations to simulate rapid response scenarios.
Integrated command and control systems that connect military leaders and units across domains.
Precision targeting and logistics coordination to ensure smooth movement of troops, supplies, and communication.
Simulated cross-border actions that require quick decision-making and coordination with political and legal authorities.
Through Trishul, the Armed Forces are also practising how to make fast and coordinated decisions during crisis situations. The exercise checks how quickly information flows between the services and how efficiently they can respond together. This makes India’s defence system more agile and less dependent on slow, individual responses.
Experts say that the public nature of Trishul also serves as a strong deterrence signal. By conducting the exercise near Pakistan’s border, India is showing that it can mobilise joint forces quickly and sustain operations across multiple domains if needed. The goal is not to provoke conflict but to deter aggression by demonstrating capability and preparedness.
The exercise also helps in developing clear rules of engagement and responsible escalation management. This ensures that while India remains ready for action, it also avoids accidental or unnecessary conflict. Defence officials believe that such joint exercises strengthen coordination and trust among the three services, making the country’s defence posture more reliable and confident.
In summary, Trishul is more than just a military drill—it is a symbol of India’s modern and united defence strategy. It builds on the lessons learned from Operation Sindoor, reflects the Post-Sindoor Doctrine of proactive deterrence, and showcases India’s ability to act firmly and intelligently in the face of security challenges.
By combining strength with coordination, and readiness with restraint, India’s Armed Forces are showing that they can protect the nation’s borders while also promoting regional stability. Trishul stands as a clear message of strength, unity, and preparedness in a complex security environment.
