"The defense in three lines with a length of 2000 kilometers is a large-scale task, but the pace is good now," Ukraine's President Zelenskyy said following a meeting with military commanders.
British intelligence reports that Ukraine constructs extensive defensive lines that will hinder Russian advances and offensive operations, requiring high-casualty breaching attempts.
Ukraine's government has allocated a record UAH 17.5 billion ($466 million) for the construction of engineering and fortification structures aimed at bolstering border defenses. Meanwhile, Estonia, Latvia, and Lithuania have agreed to build anti-mobility defensive installations along their borders with Russia and Belarus.
Considering that the active frontline extends over a distance of approximately 1,500 kilometers, there is an average of four kilometers of fortifications for each kilometer of the frontline.
