Key Points

• About:  The exercise is scheduled from 30th October to 10th November 2025 and involves large-scale participation from the Army, Navy, and Air Force and aims to enhance operational readiness, joint coordination, and multi-domain warfare capabilities.
  • The exercise, codenamed “Trishul” and internally referred to as “Mahagurjar”, will cover the Thar Desert region extending from Jaisalmer (Rajasthan) to Sir Creek (Gujarat).

  • The drills will emphasise unified operations, deep-strike missions, amphibious warfare, and multi-domain combat readiness.
  • The exercise also aims to enhance coordination among different commands and validate new indigenous weapon systems under realistic battlefield conditions.
• Scale and Participation:The Army has deployed more than 20,000 soldiers, supported by T-90S and Arjun tanks, howitzers, armed helicopters, and missile systems.
  • The IAF is conducting high-tempo ‘Mahagujraj’ operations, deploying Rafale and Sukhoi-30MKI fighter jets, transport and refuelling aircraft (IL-78), AEW&C systems, and unmanned aerial vehicles (UAVs).
