Nearly 2,000 military and civilian medical personnel from 32 nations gathered in Estonia for Exercise Vigorous Warrior 2026, one of NATO's largest medical training exercises.
The exercise is held every two years to test how well allied nations can work together to treat and evacuate casualties in a crisis. This year’s iteration was hosted by the Estonian Defence Forces and the Estonian Health Board.
The RAF Medical Force deployed its Aeromedical Staging Unit, a specialist team responsible for preparing patients for transport by air, working alongside Army Reserve personnel from 144 (Parachute) Medical Squadron, the Defence Medical Command and medical teams from across NATO.

Together, they practised the full chain of care: treating casualties at the point of injury, stabilising them, and moving them safely through to hospital treatment. The goal was to make sure that, in a real emergency, handovers between different nations and services are seamless.
"Vigorous Warrior provided the opportunity to exercise the Royal Air Force Aeromedical Staging Unit's capabilities in a complex, multinational environment. Alongside partners, we delivered seamless patient movement from the point of injury through to strategic evacuation out of theatre, putting the Operational Patient Care Pathway into practice."

For some participants, it was their first experience of a NATO exercise. Flight Lieutenant Thompson, a Reserve Medical Support Officer from 612 Medical Reserve Squadron, said: “this exercise has provided a valuable opportunity for me to observe the wide range of nationalities and capabilities involved and understand how each element contributes to achieving NATO's wider mission. Seeing different nations come together in shared purpose highlighted the capability, resilience, and success of NATO medical services in delivering an effective Operational Patient Care Pathway."
The exercise also tested the ability of military medical teams to work alongside civilian healthcare professionals, a skill that is just as important at home as it is overseas. When the RAF has been called on to support civilian authorities during emergencies such as the COVID-19 pandemic or the Salisbury nerve agent poisonings, this kind of joint working has been essential.

The training incorporated lessons from recent conflicts to make sure the RAF's approach reflects the realities of today's security environment, keeping skills sharp and procedures current.
Exercises like Vigorous Warrior are a vital part of how the RAF prepares for the unexpected. They allow medical teams to build relationships with international partners, test their skills under pressure, and return home better equipped to respond, wherever and whenever they are needed. The RAF remains committed to strengthening NATO's collective ability to protect, treat and evacuate those in harm's way.
