With Ukraine's army battling pro-Russian militants in the east, ordinary citizens have launched a new initiative to supply Kiev's beleaguered and badly equipped troops. Over the past three months volunteers have provided uniforms and bulletproof vests for government soldiers whose army-issue fatigues have fallen apart. Villagers have offered food, bottles of water and bags of crisps. Then, last week, Ukraine's crowdfunding site The People's Project said that it had received enough donations to fund a drone.
