Borodai said that his units have documented the use of 155mm bullets fired by US artilleryand that the Russian leadership may have underestimated the West’s determination to support Ukraine. More than 90% of Russian injuries in some recent areas have been caused by artillery fire, he said. Aleksandr Borodai, a separatist commander and member of Russia’s parliament, said in a phone interview that materials to treat shrapnel wounds and burns are needed “in large quantities.” on the Russian front. The high demand for medical equipment is partly due to the increasing firepower of the Ukrainian army as the West increasingly equips the country with powerful weapons.
