In the Chernihiv Oblast region of Ukraine, border guards and engineers are constructing a defensive line along the border with Belarus, transforming forests and marshland into a layered system of wire, trenches, and anti-tank concrete obstacles designed to deter any potential surprise incursion.<\/p>\n
Ukrinform\u00a0spoke directly with the border post commander Yevhen, callsign \u201cNissan,\u201d from the State Border Guard Service of Ukraine, in an on-site interview near the Ukrainian-Belarusian border in the Chernihiv region, News.Az<\/a> reports, citing Kyiv Post<\/a>.<\/p>\n \u201cEngineering barriers consist of a complex of artificial and natural obstacles,\u201d Nissan explained. \u201cArtificial ones are low-visibility wire obstacles and \u2018Egoza\u2019 [registered trademark for a highly durable type of reinforced razor wire]. Natural ones are forest blockages,\u201d he added.<\/p>\n \u201cWe use nature as an ally,\u201d Nissan said. \u201cA tree can be cut so that it falls at a certain angle and stays half-sawn. It simultaneously stands, overhangs, and seriously complicates movement for vehicles and infantry.\u201d<\/p>\n Dragon\u2019s teeth anti-tank barriers<\/p>\n \u201cDragon\u2019s teeth\u201d are concrete barriers that weigh around 1.5 tons, and are about 10 meters (33 feet) wide, designed to block likely routes for armored vehicles. In the Chernihiv region, they have been placed alongside the forest edge. Behind them, Ukrinform reports, lie deep anti-tank ditches with steep vertical walls \u2013 the result of weeks of excavator work in heavy, waterlogged soil.<\/p>\n Much of the defense system, however, remains almost invisible.\u00a0<\/p>\n Thin, strong wire is strung low between the trees as a low-visibility obstacle, while belts of \u201cEgoza\u201d razor wire form continuous traps for soldiers and a critical hazard for vehicles.<\/p>\n Nissan notes that the local terrain helps greatly \u2013 dense forest limits enemy aerial reconnaissance, and off-road heavy equipment tends to bog down in the marshes, even as those same conditions make construction more demanding.<\/p>\n Building the border since 2022<\/p>\n The commander notes that they haven\u2019t stopped building the defense layer since Russia\u2019s<\/a> initial advance through the area in 2022, when war had just begun.\u00a0<\/p>\n \u201cThe build-up of engineering infrastructure goes on constantly,\u201d Nissan said. \u201cCompared to the first months after de-occupation, volumes have increased by about 500%. It\u2019s a continuous, echeloned system that stretches for kilometers along all our land borders,\u201d he added, explaining that there can\u2019t be too many obstacles.<\/p>\n \u201cTo be sure 100% that even a bird will not fly through is impossible,\u201d Nissan said. \u201cBut we are ready for any development.\u201d<\/p>\n Behind those figures lies the daily work of digging and wiring. One excavator cuts up to about 200 meters (656 feet) of anti-tank ditch per day, depending on bucket size, and two soldiers can lay about 100 meters (328 feet) of \u201cEgoza\u201d wire in roughly four hours, with ten soldiers closing up to a kilometer in the same time.\u00a0<\/p>\n On average, as per the report, a unit can prepare around 500 meters of reliable barrier in a day.<\/p>\n
