The fortified defence line, the alleged Sorowikin Line, was decently prepared in terms of engineering and sappers even before the summertime of 2023. Above all, extended and crucial minefields were erected, which were decently covered with fire. During the offensive, Ukrainian forces knew that in the south they had to face an extensive, densely mined line of engineering-saper fortifications, but no 1 expected that the scale of fortifications and the saturation of mines would be so huge, but alternatively so strong, that after many weeks of day success, if they are, is measured in meters and single "resistances".
