Oleksiy Reznikov, who was replaced as Ukraine's defence minister on Sunday, was appointed three months before Russia's invasion and led efforts to equip Ukraine's forces with modern weaponry from allies. The 57-year-old lawyer with little military experience, usually seen in a green fleece, has become one of the best-known faces of the country's war effort. After helping hold back Russia's advance in the early months of the war, he spent much of his time in office galvanising support from Kyiv's allies. Over time, he persuaded them to supply Ukraine with more and more Western-made weaponry including US Patriot air defence systems, heavy tanks and howitzers. SHORT PROFILE OF Oleksiy Reznikov
