On the frontline of the Lugansk region, a Ukrainian artillery unit fires on Russian positions with a British L119 howitzer gun. The weapon is part of UK Prime Minister Rishi Sunak’s promise to intensify military support to Ukraine this year by matching or exceeding £2.3 billion ($2.8 billion). "If Western partners supply their artillery weapons and shells, this is immediately felt on the battlefield. We can adequately respond to the enemy and create conditions for advancing," says Oleksandr, commander of the unit.
