The Indian Army launched a large-scale Humanitarian Assistance and Disaster Relief (HADR) mission named Operation Jal Rahat in July 2026 to assist the Assam state government in rescuing people trapped by devastating monsoon floods across Upper Assam. Spearheaded by the Red Shield Division under the Spear Corps (III Corps), the operation deployed multiple Flood Relief Columns to the worst-hit districts of Sivasagar, Charaideo, and Jorhat. With relentless monsoon rains pushing the Brahmaputra and its tributaries above the danger mark, the Army evacuated over 570 stranded civilians and provided emergency medical aid, food, and drinking water to affected families.
The Flood Crisis in Assam
Assam is one of the most flood-prone states in India, with 39.58% of its land area classified as flood-prone, nearly four times the national average. The state lies within the Brahmaputra and Barak river basins, which together cover over 77,000 square kilometres. During the monsoon season, the Brahmaputra, along with its more than 50 tributaries, swells dramatically, often breaching embankments and submerging vast stretches of land.
In July 2026, heavy and continuous monsoon precipitation in the upper catchment regions of Nagaland and Arunachal Pradesh triggered a massive downstream surge into the Brahmaputra basin. More than 1.7 lakh people across 12 districts were affected, with over 580 villages submerged and more than 10,362 hectares of standing crops destroyed. The worst hit were the Upper Assam districts of Sivasagar, Charaideo, and Jorhat, where floodwaters cut off road and rail connectivity, leaving hundreds of families marooned on rooftops and high ground. At least two embankment breaches in these districts allowed floodwaters to spread deeper into populated areas, damaging railway tracks and disrupting train services across Upper Assam.
Operation Jal Rahat: Scope and Execution
On July 20, 2026, following a requisition from the civil administration, the Indian Army activated four Flood Relief Columns of the Red Shield Division under the aegis of Spear Corps. These columns were deployed across Sivasagar, Charaideo, and Jorhat districts for rescue, evacuation, and relief tasks. Each column was equipped with rescue boats, engineering equipment, emergency medical supplies, and relief stores.
The teams operated at Nazira and Amguri in Sivasagar district, Sonari in Charaideo, and in Jorhat district. Army personnel conducted round-the-clock operations to evacuate stranded residents, including children, elderly citizens, and vulnerable families. Beyond human rescue, teams helped relocate livestock to safer locations and distributed essential relief materials such as food packets and drinking water.
Helicopter reconnaissance sorties and drone flights were flown over affected areas to assess the flood situation and guide the deployment of resources. Army engineer detachments worked to restore connectivity in areas where roads and bridges had been damaged or washed away. According to Defence officials, the operation had rescued 571 people within its first phase, with additional resources kept on standby for further deployment.
The Forces Behind the Mission
Spear Corps (III Corps)
The Spear Corps, officially designated as III Corps, is a field formation of the Indian Army under the Eastern Command. It is headquartered at Rangapahar Military Station in Dimapur, Nagaland. The corps was raised on February 4, 1985, initially to coordinate and conduct counter-insurgency operations across Nagaland, Manipur, Mizoram, Tripura, Meghalaya, South Assam, and parts of Arunachal Pradesh. Over time, its role expanded to include conventional military operations along the Line of Actual Control (LAC) and disaster response. The corps was previously commanded by Lt Gen Bipin Rawat and Lt Gen Anil Chauhan, both of whom went on to become Chief of Defence Staff. The current General Officer Commanding of Spear Corps is Lt Gen Girish Kalia.
Red Shield Division (57 Mountain Division)
The Red Shield Division, formally the 57 Mountain Division, is an infantry division of the Indian Army headquartered at Leimakhong near Imphal, Manipur. It was raised in 1966 for counter-insurgency operations in Mizoram. The division saw action in the Indo-Pakistani War of 1971 as part of IV Corps and successfully conducted Operation Golden Bird in 1995, a major operation to eliminate rebels in Northeast India. The division’s formation sign, the crossed spears, gives it its nickname. Its troops are trained for mountain warfare and are deployed in some of the most remote areas of Manipur along the Indo-Myanmar border.
Inter-Agency Coordination
Operation Jal Rahat was not a standalone military mission. The Army columns operated in close synchronisation with multiple civil and disaster response agencies. These included the National Disaster Response Force (NDRF), the State Disaster Response Force (SDRF), and the Assam State Disaster Management Authority (ASDMA). The NDRF deployed 24 boats in Sivasagar and Charaideo and later reinforced the effort with two additional teams carrying 10 more boats.
At the political level, Assam Chief Minister Himanta Biswa Sarma directed cabinet ministers to visit the flood-hit districts and supervise rescue and relief operations. The District Administrations of Sivasagar, Charaideo, and Jorhat coordinated with the Army on the ground, ensuring that relief reached the most inaccessible areas. Troops from formations under Spear Corps also supported the relief columns, and the Assam Rifles provided additional assistance in search and rescue operations.
The Brahmaputra Flood Challenge
The Brahmaputra River originates in the Angsi Glacier of the Tibetan Himalayas and flows through China (Tibet), India, and Bangladesh before emptying into the Bay of Bengal. In India, it enters through Arunachal Pradesh and flows through the Assam valley, where it receives numerous tributaries including the Subansiri, Manas, Sankosh, Dhansiri, and Kopili.
The river carries one of the highest sediment loads in the world. This sediment raises the riverbed over time, reducing the carrying capacity of the channel and causing frequent breaches of embankments. Combined with extreme rainfall events, this makes Assam structurally vulnerable to annual flooding. The floods of July 2026 followed the same pattern: heavy rain in the upper catchment states of Nagaland and Arunachal Pradesh sent a colossal surge downstream, overwhelming the Brahmaputra’s main channel and its tributaries.
Urban flooding added another dimension to the crisis. Heavy overnight rain triggered flash floods in parts of Guwahati, where runoff from the Meghalaya hills and rising water levels of the Basistha River submerged low-lying residential areas. This dual challenge of riverine and urban flooding stretches the capacity of civilian disaster management agencies, which is why the Indian Army is frequently called in to augment relief efforts.
Indian Army’s Role in Humanitarian Assistance and Disaster Relief
The Indian Armed Forces have long served as first responders during natural disasters, both within India and abroad. Domestically, the Disaster Management Act, 2005 provides the legal framework for disaster response, with the primary responsibility resting with state governments. However, when disasters overwhelm civilian capacities, the Central Government deploys the Armed Forces under the principle of Aid to Civil Authorities, guided by Article 355 of the Constitution, which imposes a duty on the Union to protect states against internal disturbance.
The 2004 Indian Ocean tsunami was a watershed moment for India’s HADR framework, prompting the institutionalisation of tri-services coordination. Since then, the Indian Army has conducted major operations including:
| Operation | Year | Location | Scale |
|---|---|---|---|
| Operation Rahat / Operation Surya Hope | 2013 | Uttarakhand | Thousands rescued by IAF and Army |
| Operation Megh Rahat | 2014 | Jammu and Kashmir | 96,000 rescued, 3,500 tonnes airlifted |
| Kerala Flood Relief | 2018 | Kerala | 60,000 rescued across the state |
| Operation HIMRAHAT | 2023 | Sikkim | 1,247 tourists evacuated after GLOF |
| Nationwide Flood Relief | 2025 | 10 states, 80+ locations | 28,293 civilians rescued |
In 2025 alone, the Indian Army deployed 141 columns across more than 80 locations in ten states. Operation Jal Rahat continues this legacy, demonstrating the Army’s ability to rapidly mobilise engineering assets, satellite communication arrays, and rescue teams into complex, waterlogged terrains at short notice.
