When disasters strike, the immediate priority is saving lives. In the chaos following earthquakes, floods, or cyclones, local healthcare systems are often overwhelmed or destroyed entirely. This is where armed forces step in with their unique capability to rapidly deploy medical resources to the most inaccessible areas. Military medical teams have become indispensable first responders in disaster situations worldwide, bringing field hospitals, surgical capabilities, and disease prevention measures when they are needed most.

Field hospitals: bringing healthcare to disaster zones
A field hospital is a mobile medical facility designed to provide essential healthcare services in remote or disaster-stricken areas where permanent infrastructure has been damaged or destroyed. Armed forces maintain these deployable medical units in a state of constant readiness, allowing them to establish functional hospitals within hours of arriving at a disaster site.
Modern military field hospitals come in several forms. Tent hospitals offer large available space with lower terrain requirements, making them suitable for varied landscapes. Shelter hospitals use expandable ISO containers that create climate-controlled, sterile operating rooms capable of producing surgical outcomes similar to fixed facilities. Vehicle hospitals provide rapid mobility and can be deployed along with rescue teams. The choice depends on the specific disaster scenario, terrain conditions, and medical requirements.
Components of military field hospitals
A fully equipped military field hospital typically includes emergency departments for triage and stabilisation, operating theatres for trauma surgery, intensive care units, laboratory and diagnostic facilities including X-ray equipment, pharmacy services, and ward units for patient recovery. The U.S. Army’s Combat Support Hospitals, for instance, can deploy with between 44 and 248 hospital beds and include CT scanners, pharmacy, laboratory, and dental capabilities.
The equipment within these facilities has evolved significantly. During the 2015 Nepal earthquake response, medical teams highlighted the need for CT scanning units, as brain injuries requiring precise surgical positioning were common. This feedback has led to improvements in mobile hospital equipment standards globally.
Sanitary measures and disease control
Beyond immediate trauma care, armed forces play a critical role in preventing disease outbreaks that commonly follow disasters. When water supplies are contaminated, sanitation systems are destroyed, and large populations are displaced, the risk of epidemics increases dramatically.
Infection prevention protocols
Military medical personnel implement strict infection control practices in disaster scenarios. These include establishing clean water distribution points, setting up proper waste management systems, and creating quarantine facilities when needed. During flood relief operations, armed forces hospitals must address specific challenges like waterborne illness prevention and management of contaminated wounds.
The Sphere Project standards guide emergency sanitation practices, specifying that within the immediate phase, the focus should be on managing open defecation through basic latrines, ensuring handwashing facilities are available, and proper management of medical waste. Military teams are trained to implement these standards rapidly in austere environments.
Vector control and decontamination
Armed forces medical units also focus on vector control to prevent diseases like malaria, dengue, and other insect-borne illnesses that thrive in post-disaster conditions. This includes draining standing water where mosquitoes breed, distributing bed nets, and applying appropriate pesticides in affected areas. In situations involving chemical or radiological hazards, specialised military teams conduct decontamination operations to protect both survivors and relief workers.
Hospital ships and aerial medical assets
Beyond ground-based facilities, armed forces deploy hospital ships for coastal disaster response. The U.S. Navy operates two hospital ships, USNS Mercy and USNS Comfort, which serve as floating hospitals. The Mercy operates in the Pacific and Indian Oceans and has treated more than 400,000 patients since 2006 through humanitarian missions. China’s hospital ship Peace Ark has similarly conducted dozens of humanitarian missions, treating over 180,000 patients worldwide.
Aeromedical evacuation provides fast transportation of casualties from disaster sites to hospitals with better facilities. Military transport aircraft can be configured as flying hospitals, providing surgical and acute medical care during transit. This capability proved essential during the 2011 Japan earthquake response when the U.S. Air Force transported over 2,800 people in the first two weeks of Operation Tomodachi.
Case studies: military medical corps in action
Operation Brahma: 2025 Myanmar earthquake
One of the most recent examples of armed forces medical intervention is Operation Brahma, launched by India in response to the devastating 7.7-magnitude earthquake that struck Myanmar in March 2025. The Indian Army deployed a 118-member medical task force from the Shatrujeet Brigade, establishing first a 60-bed and then a 200-bed field hospital in Mandalay.
By the time the mission concluded, the field hospital had treated over 2,500 patients, performed 65 major surgeries, conducted more than 1,300 laboratory investigations, and completed 103 X-ray procedures. The operation also showcased technological advancement, with AI-powered robotic systems and nano drones deployed to assist rescue efforts in debris-filled terrain.
Operation Maitri: 2015 Nepal earthquake
When a 7.8-magnitude earthquake devastated Nepal in April 2015, the Indian Army Medical Corps deployed three fully equipped field hospitals near Kathmandu and other affected areas. Medical relief teams treated earthquake injuries, conducted surgeries, and distributed medical supplies to support over 8 million impacted individuals. The field hospitals used inflatable tents suitable for the mountainous terrain, demonstrating adaptability in challenging conditions.
Operation Rahat: 2013 Uttarakhand floods
During the catastrophic 2013 floods in Uttarakhand, India, the armed forces inducted over 12 medical teams and opened emergency medical helplines. The Indian Army deployed 5,600 personnel for relief and rescue operations, providing medical aid to stranded civilians while also establishing communication links for affected families. Medical teams were positioned at every 2 km along key routes to ensure rapid response to isolated casualties.
2023 Turkey-Syria earthquakes: Operation Dost
Following the devastating earthquakes in Turkey and Syria in February 2023, multiple nations deployed military medical assets. The U.S. Department of Defense constructed a 100-bed emergency hospital in less than one week to assist earthquake survivors in Tรผrkiye. Indian armed forces similarly deployed medical teams under Operation Dost, continuing the pattern of rapid military medical response to international disasters.
Recent response: 2025 Sri Lanka cyclone
In late 2025, when Cyclone Ditwah caused severe flooding in Sri Lanka, India launched Operation Sagar Bandhu. The Indian Army deployed an Integrated Task Force comprising medical teams with Advanced Dressing Stations and Mobile Surgical Teams equipped with operation theatres capable of performing major and minor surgeries. Two rapidly deployable field hospitals with 70 medical personnel were airlifted to provide healthcare support to disaster-affected areas.
The golden hour and rapid deployment
Military medical doctrine emphasises the importance of the “golden hour” – the critical first 60 minutes after a traumatic injury when prompt treatment dramatically improves survival chances. Armed forces are uniquely positioned to meet this standard in disaster scenarios due to their pre-positioned equipment, trained personnel, and transport capabilities.
Modern military medical units can be airlifted by transport aircraft and helicopters, allowing them to reach disaster zones within hours rather than days. During humanitarian relief operations, military aircraft often deliver fuel, medical equipment, and personnel simultaneously, establishing functional medical facilities before civilian aid organisations can mobilise.
Coordination with civilian agencies
Armed forces medical operations in disaster settings work in coordination with civilian health authorities, international organisations, and NGOs. The military typically provides the initial surge capacity while helping transition to longer-term civilian-led recovery efforts. This collaboration ensures that medical standards are maintained and that local healthcare systems are strengthened rather than replaced.
The Army Medical Corps of India, with its motto “Sarve Santu Niramaya” (May all be free from disease and disability), exemplifies this approach, providing services to civilians during natural disasters while maintaining its primary role of supporting military personnel. Similar principles guide military medical corps worldwide in balancing combat readiness with humanitarian response capabilities.
What do you think? As climate change increases the frequency and intensity of natural disasters, should armed forces expand their medical humanitarian capabilities, or should this investment be directed toward strengthening civilian disaster response systems instead?
