This is why Ukrainian Forces retreated at Chasiv Yar.Looks that way, has cost them alot of men to take the ground they have. Also looks like the next part has been flattened and is indefensible so will cause even more russian losses hopefully when they advance through it.
Their positions have indeed been flattened,and now the Russians occupy them positions.
Its roughly 300m².
Not that much,IMO.
Slava Ukraini.
