 A large share of German tanks were destroyed in Ukraine. Ukraine's military has lost a substantial proportion of its Leopard 2 battle tanks donated by foreign states with more than a quarter destroyed by Russian troops and the rest damaged beyond Kiev's capacity to repair them, according to Foreign Affairs magazine. While Western media reports touted the German-made tank as a game changer after Berlin authorized the transfer last year, Kiev has since discovered they are hardly invulnerable superweapons. The outlet reported, of the fewer than 100 Leopard 2s in Ukrainian service, at least 26 have been knocked out, others cannot be used due to repair and maintenance issues. Foreign Affairs wrote, adding that Ukraine lacks the extensive support infrastructure needed to maintain its fleet. The magazine also pointed to rushed training for Ukrainian tank crews by Western advisors saying they had failed to employ tight combined arms coordination to preserve armored vehicles under fire on the battlefield. The tank brigades were provided with just five weeks of instruction and were largely made up of inexperienced formations with little-to-no combat experience. Leopard 2s were employed in the earlier phases of Kiev's summer counter-offensive, but were weakly supported and made little headway against deep defensive lines established by Moscow. Germany announced transfers of the Leopard to Ukraine in early 2023 after the United States pledged 31 of its own M1 Abrams battle tanks.
