Col Oleksii Noskov, assistant commander-in-chief of Ukraine's armed forces, said: "The army of drones will allow us to constantly monitor the 2,470km-long (1,535 miles) front line and to field an effective response to enemy attacks, using modern technology."
Mykhailo Fedorov, Ukraine's minister of digital transformation, told the BBC via email that the first goal of the campaign was to purchase tactical drones which have a 100-mile range and are equipped with a sophisticated camera, GPS and mapping tools.
However, after studying the issue, he said "our team understood that Ukraine's army still needed quadcopters", and so he said the country was asking people to "donate their own drones".
Ukraine hopes to collect thousands of multi-use and commercial UAVs.
