17, the figure stands at 9,014, according to the General Staff of Ukraine's Armed Forces.At the start of the full-scale invasion, Russia was estimated to have around 3,300 operational tanks, suggesting that all those that initially drove into Ukraine and then some, have been taken out over the course of two-and-a-half years.It's impossible to know for certain exactly how many tanks Russia has lost during the full-scale invasion of Ukraine, so any figures need to be treated as estimates. Further complicating matters is what exactly Ukraine's General Staff counts as a "tank," with Ukraine's official count being plausible, yet most likely misleading. "The daily figures from Kyiv just say tanks, but because it has a separate section for armored personnel vehicles, so it's my interpretation that they group main battle tanks and infantry fighting vehicles," Sascha Bruchmann, visiting research fellow for defense and military analysis at the International Institute for Strategic Studies (IISS), told the Kyiv Independent.Opinion: How many tanks does Russia have left?How many tanks does Russia really have left? This question has come up quite frequently in discussions, and it’s simply impossible to find a precise answer – Russia’s Defense Minister Sergei Shoigu and General Staff chief Valery Gerasimov probably don’t even know.
