On 3 November 2026, HM Government announced that the UK would lead Exercise Koalicja in Poland, a multinational military training activity designed to prepare allied forces for a potential future role supporting peace in Ukraine. The government said the exercise would involve 2,800 troops from 11 nations.
HM Government said the UK contribution would include 300 troops and RAF aircraft. The government described the exercise as a test of readiness for supporting Ukraine’s long-term security and helping rebuild Ukraine’s armed forces once the conflict ended.
The exercise followed wider UK policy commitments on Ukraine. On 28 October 2026, HM Government announced a £10 billion economic and military support package for Ukraine, as GPS previously reported. On 2 November 2026, HM Government said the UK and Germany reaffirmed support for Ukraine through their Defence Ministerial Council.
The practical significance of Exercise Koalicja was that it moved allied planning from political commitment into rehearsed military coordination. According to HM Government, the activity was intended to prepare participating countries for coordinated support to Ukraine’s security, which made the drill relevant to postwar stability planning, allied interoperability and European security governance.
