Kyiv was a Russian defeat for the ages. When President Vladimir Putin launched his war on Feb. 24 after months of buildup on Ukraine's borders, he sent hundreds of helicopter-borne commandos — the best of the best of Russia's “spetsnaz” special forces soldiers — to assault and seize a lightly defended airfield on Kyiv's doorstep. Other Russian forces struck elsewhere across Ukraine, including toward the eastern city of Kharkiv as well as in the contested Donbas region and along the Black Sea coast.
