Non-Combat PTSD Nexus Letters

When most people think about posttraumatic stress disorder, they often think about combat. However, PTSD can also develop after other traumatic events, including natural disasters and disaster-response operations. For many veterans, National Guard members, reservists, and active-duty service members, hurricane-related humanitarian missions were not simply routine support assignments. They involved danger, destruction, death, injury, fear, exhaustion, and exposure to human suffering on a massive scale.

U.S. military personnel have repeatedly been activated to assist after devastating hurricanes, including Hurricane Hugo, Hurricane Andrew, Hurricane Iniki, Hurricane Mitch, Hurricane Katrina, Hurricane Sandy, Hurricane Harvey, Hurricane Maria, Hurricane Ian, and Hurricane Helene. These missions often required service members to perform search and rescue, evacuate civilians, deliver food and water, clear debris, recover bodies, support overwhelmed hospitals, restore infrastructure, and work in devastated communities where homes, families, and entire neighborhoods had been destroyed.

For some veterans, these experiences became the source of long-term psychological symptoms. A veteran may not have been deployed to a traditional combat zone, but hurricane disaster-relief operations can still involve traumatic exposure sufficient to cause PTSD when the service member directly experienced danger, witnessed death or serious injury, handled human remains, feared for their own life, or was repeatedly exposed to the suffering of others.

A hurricane-response mission may qualify as a traumatic stressor when the veteran was exposed to actual or threatened death, serious injury, or extreme human suffering. This can occur in many ways during disaster-relief operations.

Some veterans participated in rescue missions in flooded neighborhoods, unstable structures, or dangerous debris fields. Others saw deceased civilians, recovered bodies, assisted injured children or elderly survivors, or entered destroyed homes where families had lost everything. Some worked long hours with little rest while exposed to heat, contaminated floodwater, human remains, collapsed buildings, hazardous materials, or ongoing threats from unstable infrastructure.

For example, a service member responding after Hurricane Katrina may have participated in rooftop rescues, evacuation support, medical transport, or recovery operations in flooded areas. A National Guard member responding after Hurricane Andrew or Hurricane Hugo may have entered neighborhoods destroyed by wind damage, helped displaced families, or provided security and aid in devastated communities. A military responder after Hurricane Maria, Ian, or Helene may have flown supplies into isolated areas, performed rescue operations, or encountered civilians stranded without electricity, medical care, food, or clean water.

These experiences can leave a lasting psychological imprint. Even when the mission is humanitarian, the responder may still be exposed to trauma.

Veterans who developed PTSD after hurricane-related disaster relief may experience symptoms such as:

• Intrusive memories of the disaster scene
• Nightmares involving flooding, destruction, bodies, screams, or trapped civilians
• Flashbacks triggered by storms, heavy rain, wind, emergency sirens, helicopters, or news coverage of disasters
• Avoidance of storm-related media, hurricane season coverage, or conversations about the mission
• Emotional numbness or detachment from family
• Survivor’s guilt, especially if civilians or fellow responders could not be saved
• Hypervigilance during bad weather
• Irritability, anger outbursts, or emotional dysregulation
• Sleep disturbance, including insomnia and frequent waking
• Anxiety during hurricane season
• Depression, hopelessness, or loss of interest in activities
• Difficulty concentrating
• Increased alcohol use or other maladaptive coping behaviors

These symptoms may begin soon after the mission, or they may emerge gradually over time. Some veterans initially minimize their symptoms because they believe they were “only helping” or because they compare their experience to combat trauma. However, PTSD is not limited to combat. Humanitarian disaster-response work can expose service members to severe psychological trauma.

Hurricane Hugo in 1989, which caused catastrophic damage in South Carolina, Puerto Rico, and the U.S. Virgin Islands. Military and National Guard personnel assisted with relief, security, infrastructure support, and recovery operations. 

Hurricane Andrew in 1992, which devastated South Florida and required a major military response, including Joint Task Force Andrew and active-duty Army support. Service members assisted with logistics, supply distribution, security, rebuilding support, and relief operations in severely damaged communities. 

Hurricane Mitch in 1998, which caused catastrophic loss of life and destruction in Central America. U.S. military personnel supported humanitarian assistance, helicopter missions, rescue support, and regional disaster relief. 

Hurricane Katrina in 2005, one of the most significant domestic disaster-response missions in modern U.S. history. Military personnel assisted with rescue, evacuation, food and water distribution, medical support, logistics, and security in Louisiana, Mississippi, and surrounding areas. 

Hurricane Sandy in 2012, which caused severe damage across the Northeast. National Guard personnel and the U.S. Army Corps of Engineers assisted with evacuations, infrastructure recovery, food and water distribution, and dewatering operations. 

Hurricane Harvey in 2017, which caused catastrophic flooding in Texas. National Guard and other military forces assisted with high-water rescues, evacuations, logistics, and supply distribution. 

Hurricane Maria in 2017, which devastated Puerto Rico and the U.S. Virgin Islands. Military personnel supported food and water delivery, logistics, medical assistance, airlift, infrastructure support, and disaster-response coordination. 

Hurricane Ian in 2022, which caused major destruction in Florida and required military support for rescue, medical evacuation, aviation support, road clearing, and supply distribution. 

Hurricane Helene in 2024, which caused catastrophic damage in parts of the southeastern United States, including isolated mountain communities. Military personnel supported aviation missions, logistics, search and rescue, food and water delivery, engineering support, and emergency response operations.
