Next week Exercise Koalicja will send about 2,800 personnel to Poland to practice a fast move of ground units and aircraft that would theoretically follow a ceasefire in Ukraine. Britain and France lead the grouping, which the UK Ministry of Defence describes as a non-NATO reassurance effort to help Kyiv rebuild rather than a peacekeeping mission. Participating jets include British Eurofighter Typhoon interceptors and Voyager tankers, and the force is designed to operate without American equipment.
