Minutes after tank muzzles flashed and the crack of guns rang out across muddy grounds, the head of the EU's Special Training Command explained how Ukraine is seeking more training on offensive tactics and the education of military leaders.

Eighteen months after Russia's February 2022 invasion, Kyiv's requests have changed from an initial need for training on defensive tactics and how to fight in urban areas, Lt. Gen. Andreas Marlow told reporters on a visit to a training ground in Germany on Thursday.

"The training of sergeants and officers is what moves the Ukrainians most because the professional soldiers have been fighting this war for one and a half years now, and many have died or been wounded — so they need a fresh supply of military leaders," he said.
