Poland to Host First Large-Scale 'Coalition of the Willing' Exercises for Ukraine Security Guarantees in Autumn 2026

Poland will host the first large-scale exercises of the 'Coalition of the Willing' for Ukraine's security guarantees in autumn 2026. The drills are scheduled for October and November 2026, according to the announcement.

Military personnel from coalition countries will participate, including forces from the United Kingdom and France. The maneuvers are intended to test how ready the allies are to act together and to form part of the groundwork for future security guarantees for Ukraine.

By staging the exercises, the coalition seeks to translate its political commitments into coordinated military preparedness. Rehearsing joint operations would allow participating nations to evaluate command, planning, and interoperability procedures that could underpin any future guarantee arrangement. The drills mark a shift from diplomatic pledges toward practical, operational planning for Ukraine's security.

No additional information was released about the exact venues, number of troops, full list of participating countries, or specific scenarios to be rehearsed.
