Mastering Riverine Warfare with Joint Force Synergy and Modernization
In May 2025, the Indian Army conducted Exercise Teesta Prahar, a large-scale integrated field exercise at the Teesta Field Firing Range in West Bengal. Orchestrated by the Trishakti Corps under the Eastern Command, this three-day drill from May 8 to 10 demonstrated the Army’s operational readiness in the challenging riverine terrain of North Bengal’s Siliguri Corridor, also known as the “Chicken’s Neck.” The exercise highlighted the Army’s commitment to joint force integration, technological advancement, and combat excellence, reinforcing its preparedness for modern warfare scenarios.
Strategic Context: Conducted near the geopolitically sensitive Siliguri Corridor, Teesta Prahar underscored India’s military readiness amid regional tensions, following the successful Operation Sindoor against cross-border threats.

A standout feature was the operational use of cutting-edge technologies, reflecting the Indian Army’s modernization drive. The exercise validated advanced battlefield systems, enhancing operational agility and situational awareness. This aligns with the Army’s shift toward technology-driven warfare, crucial for multi-domain operations.
Highlight: The deployment of advanced surveillance and communication systems during Teesta Prahar demonstrated the Army’s focus on network-centric warfare, enabling swift and synchronized operations.
Strategic Significance
- Geopolitical Context: Conducted near the Siliguri Corridor, a critical link to India’s Northeast, amid tensions following Bangladesh’s political shifts and Operation Sindoor.
- Operation Sindoor Backdrop: The exercise reinforced India’s strategic doctrine of decisive response to cross-border threats, as demonstrated in recent operations.
- Regional Preparedness: Strengthened combat readiness in a sensitive region bordering China, Bangladesh, Nepal, and Bhutan.
Teesta Prahar’s timing is notable, following Operation Sindoor, which redefined India’s stance against state-backed terrorism. The Siliguri Corridor’s proximity to international borders makes such exercises vital for maintaining deterrence. The drill also responded to regional complexities, including Bangladesh’s interim government’s pro-China and pro-Pakistan leanings post-August 2024.
Broader Implications
- Combat Excellence: The exercise reaffirmed the Army’s ability to deliver decisive outcomes across varied terrains and threats.
- Interoperability: Enhanced coordination with other services, building on joint Army-Air Force operations.
- Environmental Responsibility: Conducted with awareness of the Teesta region’s ecological sensitivity, balancing operational and environmental goals.
Teesta Prahar is part of a series of exercises in the Siliguri Corridor, including “Devil’s Strike” and “SarvShakti,” reflecting heightened focus on the region’s security. It serves as a template for future strategies, combining agility, technology, and jointness to address hybrid warfare and border challenges.
