The Op Sindoor lessons—not just how to fight wars, but also how not to

What Happened

• Operation Sindoor, a 88-hour armed conflict between India and Pakistan in May 2025, is being analysed as a watershed moment in South Asian security that fundamentally altered the paradigm of bilateral conflict — moving from mass mobilisation to precision, long-range, standoff engagement.
• India struck 11 Pakistani air bases and military facilities — including Nur Khan and Shahbaz airbases — and destroyed nine high-value terror launchpads linked to designated terrorist organisations, using a combination of BrahMos cruise missiles, SCALP air-launched missiles, Pinaka multi-barrel rocket systems, and loitering munitions.
• The Indian Air Force achieved air superiority over key Pakistani airspace sectors; the S-400 air defence system and the Akashteer integrated air defence management system were repositioned and played a decisive role in intercepting hundreds of Pakistani drones and missiles.
• Critically, neither side crossed borders with traditional armoured formations or ground forces — the conflict established that long-range standoff capability now substitutes for mass movement of troops and armoured columns.
• Analysts note that India demonstrated the ability to sustain precision operations while maintaining strategic restraint, managing escalation, and simultaneously conducting information warfare directed at domestic audiences, adversaries, and the international community.

Cross-Border Terrorism and India's Strategic Response Doctrine

India's response to cross-border terrorism has evolved through several doctrinal shifts. The Pahalgam terror attack of April 22, 2025 — in which 26 civilians were killed — triggered Operation Sindoor under India's stated right to self-defence in response to state-sponsored terrorism. India's counter-terrorism doctrine has evolved from the "strategic restraint" posture maintained after the 2001 Parliament attack and 26/11 Mumbai attacks, to the limited "surgical strikes" doctrine demonstrated in 2016 (after the Uri attack), to the air power demonstration at Balakot (2019), and now the broader multi-domain precision campaign of Operation Sindoor (2025). Each escalation level has been calibrated to impose costs on terrorist infrastructure while managing nuclear thresholds — a concept analysts describe as the "sub-conventional space" between full-scale war and no response.

Modern Warfare: Precision, Standoff, and Multi-Domain Operations

The concept of multi-domain operations (MDO) refers to the conduct of warfare simultaneously across land, sea, air, space, and cyberspace, with actions in each domain designed to create convergent effects. Operation Sindoor demonstrated several characteristics of modern MDO: use of long-range standoff systems (BrahMos: supersonic cruise missile, range ~450 km; SCALP: air-launched deep strike missile, range ~500 km); employment of loitering munitions (also called kamikaze drones or suicide drones) for persistent, cost-effective engagement; integrated air defence through S-400 and Akashteer (India's indigenous Air Defence Tactical Control System); and real-time C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance) for compressed sensor-to-shooter timelines. The shift from mass mobilisation to precision standoff reflects a global trend — similar to conflicts in Ukraine, Nagorno-Karabakh, and the Middle East — confirming that range now substitutes for mass.

Jointness and Theatre Commands in Indian Armed Forces

Jointness refers to the seamless integration of the three services (Army, Navy, Air Force) in planning and executing operations, with shared intelligence, logistics, and command. India has historically operated with single-service silos, but has been undergoing a major structural reform: the appointment of the first Chief of Defence Staff (CDS) in January 2020, followed by the process of creating Integrated Theatre Commands (ITCs). Theatre commands would place all military assets in a geographic area (such as the Northern Theatre covering China, or the Western Theatre covering Pakistan) under a single theatre commander, replacing the current system of 17 independent service commands. Operation Sindoor tested — and reportedly demonstrated the value of — joint operations: sources cited in the article note that "without jointness, C4ISR collapses into fragmentation; without jointness, speed becomes confusion."

Drone Warfare and Asymmetric Conflict

Drone warfare has emerged as a defining feature of 21st-century conflict, democratising precision strike capability and enabling persistent surveillance and engagement at costs far below manned aviation. Loitering munitions and unmanned aerial systems (UAS) were prominently deployed on both sides during Operation Sindoor. For internal security, drones pose significant threats along the India-Pakistan border — used by non-state actors for arms and drug smuggling into Punjab and Jammu. The Ministry of Home Affairs and the Indian Army have both invested in counter-drone (C-UAS) technology including gun-based, jamming-based, and missile-based interception. The Akashteer system's success in intercepting hundreds of Pakistani drones during Operation Sindoor is being cited as a validation of India's C-UAS investment.

Information Warfare and Narrative Control

Information warfare (IW) involves the use of information and disinformation to shape perceptions, undermine adversary decision-making, and manage domestic and international audiences during and after a conflict. Operation Sindoor was characterised by simultaneous kinetic action and intense information operations — including managing the narrative for Indian audiences, countering Pakistani information operations, and shaping perceptions among international observers to frame India's actions as proportionate and targeted. The article explicitly notes that "information and battlespace shaping is not limited just to tactical manoeuvre but to narrative warfare." This mirrors the concept of "cognitive warfare" — targeting the enemy's will and decision-making as much as physical assets.

Key Facts & Data

• Operation Sindoor: May 7–10, 2025; duration: 88 hours; trigger: Pahalgam terror attack, April 22, 2025 (26 civilians killed)
• Indian strikes: 11 Pakistani air bases and military facilities; 9 terror launchpads destroyed
• Terror organisations targeted: Lashkar-e-Taiba (LeT), Jaish-e-Mohammed (JeM), Hizbul Mujahideen
• Platforms used: BrahMos cruise missiles, SCALP air-launched missiles (via Rafale jets), Pinaka MBRL, loitering munitions
• Air defence: S-400 Triumf ($5.43 billion deal, 2018); Akashteer integrated air defence system (indigenously developed by BEL)
• Key doctrinal shift: mass mobilisation → long-range standoff precision strikes; range substitutes for mass troop movement
• Escalation management: no ground forces or armoured columns crossed the border; nuclear threshold preserved
• CDS created: January 1, 2020 — enables joint theatre command planning
• UAPA, 1967: India's primary legislation for designating and prosecuting terrorist organisations
• India's nuclear doctrine: No-First-Use (NFU); credible minimum deterrence; massive retaliation if NFU violated
• S-400 and SCALP acquisition both involved geopolitical tensions (S-400: US CAATSA waiver; SCALP: part of Rafale deal); both were vindicated operationally in Sindoor
