British troops and their European allies stationed as peacekeepers in Ukraine following any future ceasefire would be permitted to return fire if attacked by Russian forces, according to western officials familiar with the planning. The proposed Anglo-French led stabilization force is expected to be almost exclusively European and would operate without relying on United States military systems or technology, including Elon Musk’s Starlink satellite network.
“Clearly we will protect our forces against any aggression,” said an official familiar with the plans, though they emphasized that any western troop deployment inside Ukraine would engage in operations that remain strictly “defensive in nature.”
The framework details emerged as the UK and France prepare to launch Exercise Koalicja later this month in Poland. The upcoming exercise serves as an 11-country rehearsal designed to test how European militaries could rapidly deploy to Ukraine if the ongoing war reaches a cessation. The multinational readiness test will involve 2,800 military personnel, including 1,500 troops supplied by France from its 1st Division and 300 soldiers from the British Army’s 7th Light Mechanised Brigade.
Although a future peacekeeping deployment in support of Kyiv remains hypothetical, defense planners note the necessity of preparing for potential hostilities. Officials point to Russia’s history of low-level attacks during the previous Ukraine ceasefire period between 2014 and 2022 as a key operational risk.
Lt Gen Tom Bateman, the commander of the multinational force, stated that the UK, France, and partner nations remain committed “to providing robust and binding security guarantees for Ukraine following a cessation of hostilities.” He explained that the primary purpose of Exercise Koalicja is to demonstrate that participating countries possess the necessary “military preparedness, rapid deployment capabilities and ability to operate effectively,” putting into practice operational plans that have been under development for more than a year.
Alongside the UK and France, the nations participating in the deployment plans and exercises include Poland, Germany, Belgium, Estonia, Lithuania, the Netherlands, Spain, Sweden, and Turkey.
Bateman emphasized that the proposed force is “non-Nato,” meaning it would function entirely outside the western military alliance and operate with little to no US support if deployed into Ukraine. Deliberate steps are being taken to avoid incorporating American technology into the command and logistics structure. When asked specifically about communications infrastructure, an official confirmed that the multinational force is “not dependent on US systems” such as Starlink.
The structural independence comes as international concerns persist regarding the reliability of US support for international allies. Last month, Washington temporarily restricted Ukraine’s military variant of Starlink, known as Starshield, for approximately 10 days, an interruption that affected medium-range drone missions. While the US has previously sought to lead diplomatic negotiations between Russia and Ukraine, President Donald Trump has stated that American forces would not be committed to peacekeeping duties in Ukraine under a durable ceasefire agreement.
Diplomatic efforts to secure peace have yielded limited progress this autumn, although plans remain active for three-way talks brokered by the US later this month. Meanwhile, active combat continues, with both nations recently targeting each other’s energy infrastructure. On Sunday and Monday, both Ukrainian and Russian air-raid alert apps experienced cyberattacks. The Ukrainian application temporarily issued false warnings regarding nuclear and chemical threats as well as urban streetfighting.
Beyond basic stabilization, Bateman noted that a key objective for the multinational force would be to assist in “regenerating and strengthening” Ukraine’s military after the war concludes. Current operational concepts intend for western troops to be stationed well away from active frontlines. Nevertheless, the established rules of engagement would permit troops to defend themselves against potential Russian drone strikes, raising complex questions about how Moscow might react to armed defensive incidents.
Additional specialized operations are also under consideration to support Ukraine’s post-conflict recovery. Fighter jets are expected to help secure the reopening of Ukraine’s commercial airports through regular patrols, while separate plans are underway to clear naval mines in the Black Sea to restore maritime trade and grain exports, an operation intended to be led by Turkey.
