A Ukrainian unit fires with a 105mm M119 towed-howitzer towards a Russian position near Bakhmut, in eastern Ukraine. "This gun is great. It's accurate, it's small so we can hide it where we can and it's easy to transport", says 22 year-old 'Griva', the commander of the unit. "During the last night, enemy was trying to take some new positions... their attack was successfully defeated" he adds. IMAGES AND SOUNDBITES
