The UK and France are leading Exercise Koalicja in Poland, a multinational military exercise designed to test how to move, protect and supply a force that would help rebuild Ukraine’s Armed Forces once the fighting ends.
The exercise is the first major drill conducted by the Multinational Force-Ukraine (MNF-U), the military component of the Coalition of the Willing.
Taking place from 9–22 November 2026, the exercise will involve forces from 11 nations and focus on logistics, command structures and coordination across land, air and maritime operations.
Key developments:
- 2,800 personnel from 11 countries will participate, including 300 UK troops.
- The MNF-U, commanded by Lieutenant General Tom Bateman, would only deploy after hostilities end and at Ukraine’s request.
- The force is intended to support Ukraine’s defence regeneration, rather than operate as a peacekeeping or ceasefire-monitoring mission.
The exercise reflects wider efforts by European allies to develop a long-term security framework for Ukraine beyond the immediate battlefield.
As questions remain over the future shape of European defence and the role of the United States in regional security, initiatives such as the Multinational Force-Ukraine highlight attempts by European partners to strengthen deterrence, reassure Kyiv and prepare for potential post-conflict challenges.
The success of such arrangements will depend on political unity among participating states, Ukraine’s security needs and the terms of any future settlement.
