I would guess that the Ukrainian successes and targeting were helped massively by western support and intelligence, but they won’t want to make that publicExactly. Find it difficult to comprehend how badly the Russians have played this tactically compared to the Ukrainians. Russia have used thousands of long range and guided missiles against Ukrainian infrastructure or just randomly at residential areas. There have been a few claims of military targets being hit but very few and far between. They must have shocking intelligence if they can't identify military factories, HQ positions arms manufacturing plants etc. Let alone the staging encampments of all these new brigades that were assembling prior to Ukraines counteroffensive.
Compare that to Ukraines tactics in the past month. Airfields, ships, naval repair facilities, bridges, command posts, ammunition dumps, HQ buildings. All to degrade Russias fighting capabilities. Chalk and Cheese
