Tracking Russia’s invasion of Ukraine

IN THE EARLY hours of February 24th Vladimir Putin, Russia’s president, announced a “special military operation” in Ukraine. An initial wave of missiles struck several of Ukraine’s airports and other targets across the country, all of which Russia claimed were military. Armoured forces then began rolling in not just from Russia but also from Belarus. They were the vanguard of a force of over 150,000 troops, organised in over 110 of the battalion tactical groups which are Russia’s basic fighting formation.
