The Interflex training operation is one of the key elements of the United Kingdom’s practical military support for Ukraine, together with partner countries. Since 2022, more than 62,000 servicemen and women of the Armed Forces of Ukraine have completed training under the programme, and funding for the operation has been extended until the end of 2026.
Its aim is to rapidly and systematically prepare Ukrainian troops for modern high‑intensity warfare. The training takes place on the territory of the United Kingdom with the participation of instructors from partner nations.
The programme became the successor to the UK’s Orbital mission, which operated before the full‑scale invasion and focused on long‑term training. Interflex, by contrast, is adapted to wartime realities and the immediate needs of the front “here and now.”
The operation is led by the UK Armed Forces. Instructors from more than ten partner countries have also joined the effort, including states from Europe, North America and Oceania.
This format makes it possible to combine diverse combat experience and NATO standards.
The basic Interflex course lasts several weeks and covers the key skills required on the battlefield:
– individual infantry training;
– small‑unit tactical operations;
– live‑fire training and weapons handling;
– combat engineering and mine safety;
– tactical medicine;
– operations in urban environments and trench warfare.
The programme is constantly updated based on the combat experience of the Armed Forces of Ukraine and changes in enemy tactics. In terms of scale and volume of training, Interflex is one of the largest training missions for a foreign army undertaken by the United Kingdom in recent decades.
Interflex is not only a training project but also an investment in Ukraine’s resilience, in increasing the combat effectiveness of its troops, and in saving the lives of military personnel.
