Ukraine: Four years between war and emergency response
Published on 24. February 2026
from Jonas Gruenwald

Russia launched its full-scale invasion of Ukraine in February 2022. The fighting has been going on for four years now, and with it our humanitarian assistance on the ground.
This February is the coldest month of war since the start of the Russian war of aggression in Ukraine four years ago. Regular attacks on the energy supply are leaving local people freezing in their homes and paralyzing their daily lives. The elderly, sick, injured and children are particularly affected by power cuts and energy shortages. A war strategy that violates international law – as so often in the last four years.
Our teams also have to adapt to the harsh conditions. The winter makes our MedEvacs, i.e. the transportation of seriously ill and injured people, more difficult anyway due to snow-covered roads and poor visibility. The Russian attacks add to the pressure. Our teams were also directly affected twice, with damage to buildings and ambulances. A risk that we were aware of from the outset.
Extensive support
Four years have passed since our first team set off for Ukraine to provide emergency medical aid. At that time, it was not possible to predict how long this war would last.
Since then, we have organized numerous transports of materials, delivered dozens of rescue vehicles, partially expanded them ourselves, supported the reconstruction with technical teams and conducted many training courses in the fields of medicine and crafts. Collaboration with numerous organizations has shaped our work over the years and has had a particularly profound impact on our work with Ukrainian initiatives.
Four years of CADUS emergency aid in Ukraine
With our now three MedEvac teams in Sumy, Dnipro and Pavlohrad, we primarily fill a gap in the local rescue chain: we specialize in the transfer of patients who require intensive medical treatment. The combination of complex medical care, long journeys on challenging roads and working in an active war zone is what makes MedEvacs so demanding. Nevertheless, in four years we have been able to transport over 2,000 patients on more than 1,700 MedEvacs, covering around 300,000 kilometers.
Customize help
With the widespread use of drones, the war in Ukraine currently represents a new type of warfare like no other. The result remains the same: suffering, death and destruction.
But we are also adapting to counter the recurring consequences of war. For example, in collaboration with the Karolinska Institute and Harvard Medical School, we are developing a new type of course on emergency medical care for young children. With the subsequent training courses for Ukrainian specialists, we are creating added value beyond the end of the war.
“It is shocking that this war has already lasted four years. These are four years in which Ukrainians have already had to fight for survival under extreme conditions. We will continue to help where necessary in the fifth year!”
Ronja Heinemann, CADUS Country Manager Ukraine
The fifth year of the war
However, this still seems a long way off. The Ukrainians are not only struggling with the Russian attacks and the harsh winter, but also with dwindling international support and global public fatigue. We, on the other hand, will continue to bring humanitarian aid to Ukraine.
On the one hand, we are proud of our tireless efforts over the past four years, the support of our donors and supporters and the commitment of our partners on the ground. On the other hand, we are saddened by the fact that humanitarian emergency aid has been needed for years.
Nevertheless, we continue to hope for an early, just peace and a self-determined life in security and freedom for the people in Ukraine. And thus also for an early end to our mission!
Three years of war in Ukraine – three years of emergency response
It is exactly three years to the day since Russia attacked Ukraine. 11 years since the occupation of Crimea. For the people of Ukraine, this means having to live their lives under the most adverse conditions, despite death and destruction. We have been supporting the people in Ukraine for three years. A contribution from our team in Ukraine:
Hardened fronts – CADUS annual review 2024
The year 2024 was special for us in three ways: we celebrated our 10th anniversary, embarked on our most challenging mission to date and, after several busy years, finally classified ourselves as an Emergency Medical Team. But first things
CADUS at 38c3 – Reports from the field and a very special job center
At the end of 2024, we really went all out once again: At the Chaos Communication Congress 38C3, there were several presentations by CADUS and a rather unusual humanitarian job consultation.
