Russia’s Tactical Shift in Ukraine Raises Prospect of a Protracted War

From a Wall Street Journal story by Alan Cullison headlined “Russia’s Tactical Shift in Ukraine Raises Prospect of a Protracted War”:

KYIV, Ukraine—Russia’s steady advances in eastern Ukraine, relying on superior firepower and larger numbers of troops, are grinding down Ukraine’s military and setting the stage for a protracted war of attrition in which Kyiv needs more Western weapons and help training new soldiers to turn the tide.

After early missteps, Russia has found tactics that are working. In the invasion’s opening phase, Moscow’s armies tried to make daring thrusts deep into Ukrainian territory. They largely failed and lost elite units in the process. Now, Russian forces are advancing by increments under the cover of artillery.
