You should check out Telegram and Youtube, you have numerous videos and photos of destroyed Ukrainian armor, drone strikes on radars and artillery, while analysts count everything. The brigades were already at most 50% of capacity before the offensive, but many have been rendered combat ineffective since, meaning there are too many casualties to be able to continue operations, so the reserve brigades (many of which were meant to exploit the breakthrough if it succeeded) have been rotated in already. In short, Ukraine broke its teeth on the screening line so now they are throwing everything but the kitchen sink at the front. After the offensive stalls for good and the Rasputitsa begins, Russia will most likely begin its own offensive, which will be disastrous for Ukraine.
