In the eastern Donetsk region at the front, a Ukrainian artillery unit fires a TRF1 155mm French towed howitzer towards the Russian lines. "Since we started using it, we've done more than 600 rounds of firing" says Vadym, the unit's commander. "It can hit the target with regular ammunition from a distance of 24 kilometres (...) in terms of precision it's good". "This is a big threat" for the Russians, he adds. IMAGES AND SOUNDBITES
