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.
