Ukraine is using its new arsenal of Western tanks and armored vehicles in what is expected to be one of the largest military operations in Europe since World War II.
Military analysts and U.S. officials said it was too soon to judge the success of Ukraine’s offensive, which is looking for weaknesses to exploit, in the face of fierce resistance.
The assaults, with Western tanks and armored vehicles, appear to mark a long-awaited counteroffensive that Ukraine hopes will retake territory and shore up allies’ resolve to keep supplying weapons.
