The war began Feb. 24 with a pell-mell rush to Kyiv that ended in a 40-mile traffic jam of Russian vehicles. The Russian military showed itself unable to synchronize or supply fast-moving air and ground operations. It never even managed to secure air supremacy — the sine qua non of military effectiveness since roughly 1939.

The Ukrainians, on the other hand, proved themselves masters of hit-and-run tactics utilizing portable Western missiles such as the Javelin and Stinger.
