In the chaos of the battle for Barinkove, on the eastern front of Ukraine, Iryna Rybakova, press-officer of the 93 brigade, shows us a three-metre high cylinder with fins, planted in a field, which is the propellant of a Tochka, a huge short-range ballistic missile made in the Soviet Union. She explains that the Russians' tactic is to "intimidate" the Ukrainians with their big guns, which they cannot respond to due to a lack of means. After two months on this burning front of the war under Russian fire and two weeks of trying to contain the Kremlin-ordered assault on this concentrated offensive, things are not going so well.
