European allies are preparing to demonstrate that they could move quickly into Ukraine after a ceasefire — but the exercise also underlines how uncertain both peace and any subsequent deployment remain.

Britain and France will lead Exercise Koalicja in Poland, with about 2,800 personnel from 11 European countries rehearsing the movement, protection and supply of a multinational force. Supporters describe it as preparation for Ukraine’s long-term security rather than a combat mission. Lt Gen Tom Bateman, the force’s commander, said the participants were committed to “robust and binding security guarantees for Ukraine following a cessation of hostilities.”¹

That defensive framing is central to the European case. Officials say the Multinational Force–Ukraine would operate outside NATO command, stay away from the front line and focus on rebuilding Ukraine’s armed forces, logistics and training. The force would nevertheless be able to defend itself if attacked. Defence Secretary Wes Streeting called it “a real force, ready to help Ukraine once the fighting stops.”²

Coverage focused on the risks stresses the gap between that limited mandate and the political reality of putting foreign troops in Ukraine. Russia has opposed such deployments, with President Vladimir Putin previously saying international troops could become “legitimate targets.”³ The prospect of self-defence against drones or other attacks could therefore create pressure for escalation even if the mission is not designed for offensive operations.

Other reporting highlights a more practical debate: whether scarce European resources should be concentrated on helping Ukraine prevail now rather than planning for a postwar mission. It also notes that Ukrainian forces, already experienced in drone warfare, could train their European counterparts as well as receive support.⁴

The exercise includes British soldiers, French troops, RAF aircraft and a Turkish-led maritime component intended to rehearse mine clearance and the eventual reopening of Black Sea trade. Yet the United States is not part of the planned force, and officials acknowledge that its eventual scale would depend on a ceasefire, political decisions in participating capitals and conditions on the ground. With no clear sign that Russia is ready to end the war, the drill remains a rehearsal for a peace that has not arrived.
