Overseas veterans preventing in Ukraine face intense fight, severe psychological well being challenges, and restricted entry to care, leaving many with out satisfactory help.
Drone strikes, trench fight, and fixed frontline hazard have turn out to be defining options of the battle in Ukraine. Now, a brand new UK research means that overseas army veterans who volunteered to combat within the battle could also be paying a long-lasting bodily and psychological value, typically with out satisfactory medical help.
Led by Dr. Victoria Williamson of the University of Bath’s Department of Psychology, the research examined the experiences and well-being of army veterans from the US and United Kingdom who volunteered to help Ukraine after the battle intensified in 2022.
Printed within the European Journal of Psychotraumatology, the analysis highlights the acute situations many volunteers encountered, together with drone assaults, trench warfare, and frequent accidents.
Many members stated they obtained little formal coaching or preparation from the Ukrainian army earlier than being assigned to frontline items. In addition they described medical care in Ukraine as insufficient or unavailable. After returning residence, some continued to cope with untreated accidents and ongoing psychological well being issues.
Extreme Fight Publicity and Lack of Preparation
The researchers discovered widespread psychological misery amongst members. Many confirmed indicators in step with post-traumatic stress dysfunction (PTSD), other common mental health conditions, alcohol misuse, reduced quality of life, and distress linked to moral injury.
Moral injury refers to severe psychological distress that can occur when someone witnesses or participates in actions that conflict with their deeply held moral values. It is often associated with lasting feelings of shame, guilt, disgust, or anger.
Many veterans reported repeatedly seeking mental health treatment while in Ukraine and again after returning to the United States or the United Kingdom. However, they frequently encountered long waiting lists or were unable to access services.
Because of these barriers, many relied primarily on fellow volunteers for emotional support instead of professional healthcare providers or military leadership, both during their time in Ukraine and after returning home.
PTSD, Moral Injury, and Barriers to Care
Since Russia’s full-scale invasion of Ukraine in 2022, large numbers of military veterans have traveled to support the Ukrainian Armed Forces. Reports indicate that nearly 20,000 foreign nationals applied to join Ukraine’s military following the invasion, often motivated by political beliefs or personal convictions.
A substantial share of these volunteers came from the United States and the United Kingdom. Estimates suggest that about 3,000 Americans applied to join the International Legion. Because these fighters operate outside traditional military structures, their healthcare and support needs may go unnoticed within existing systems.
The study included 31 participants who completed psychological assessments. Of those, 21 also took part in detailed interviews about their experiences in the conflict zone.
The researchers warn that, without coordinated and specialized support, these veterans could become an overlooked population with serious unmet physical and mental health needs. They call for improved clinical pathways tailored to the unique circumstances of people who voluntarily travel abroad to fight in armed conflicts.
Foreign Veteran Volunteers: An Overlooked Group
Dr. Williamson, who also serves as president of the UK Psychological Trauma Society, said: “This is the first study to examine the experiences and health of UK and US veterans who have volunteered to fight in Ukraine. Many have described extremely intense combat, including sustained frontline exposure and persistent drone-related threats, often with limited preparation or support. Their psychological distress should not be surprising.
“The nature of combat in Ukraine is fundamentally different from other recent conflicts such as Iraq and Afghanistan. In those wars, Western personnel operated within formal military systems, with clear rules of engagement, structured command chains, and established legal and welfare protections. They received preparation before deployment and support on return.
“In contrast, many foreign volunteers in Ukraine are effectively self-deployed into a far less predictable environment. Levels of training, leadership, equipment, and medical support can vary considerably.
“Our study showed significant gaps in understanding of the clinical and welfare support needed by people subjected to these conditions. Without coordinated and informed care pathways, there is a real risk that this group will fall through the cracks and remain unsupported.”
Why Ukraine’s War Creates Unique Mental Health Risks
The researchers emphasize that the psychological effects of war extend beyond volunteer fighters and professional militaries. In current conflicts, such as the US/Israel/Iran war – which has involved large-scale missile and drone strikes on urban areas, schools, airports, and other civilian infrastructure, along with mass displacement – both civilians and military personnel are facing significant psychological strain.
These conditions are well-established contributors to trauma-related mental health problems. The researchers argue that providing timely and accessible psychological support to everyone affected by modern warfare should be treated as an urgent global priority.
