Russia has redoubled its offensive in Donbas over the past month, making significant advances as Ukraine awaits a boost in Western arms supplies. Ukraine has been warning for months about shortages in ammunition, blaming delays and indecision over Western supplies. Washington last month finally approved a $61 billion aid package but observers warn that it will take time for that aid to materialise on the battlefield. "These two months in the war will be very, very, very intense", says Yuri Fedorenko, commander of the "Achilles" drone battalion of the 92nd brigade. "The enemy will try to take as much as possible at the moment." IMAGES AND SOUNDBITES
