The constant buzzing of drones in the skies amid the roar of artillery fire has become part of daily life for soldiers on the front lines in Ukraine.

Drones - small in size and often cheap - have the capacity to locate soldiers and ammunition supplies, drop bombs and provide better visuals of what is happening on the battlefield.

And in the year since Russia invaded Ukraine they have become an integral part of the war, with both sides playing a game of 'cat and mouse' to see who can come up with the best technology and tactics.

While Russia has far greater resources - both in terms of soldiers and equipment - Kyiv believes drone innovation is one area where it can begin to catch up with Moscow. 

For Dr David Jordan, Co-Director of the Freeman Air & Space Institute at King's College London, Ukraine has gained a 'greater benefit' from drones compared to Russia as they have acted 'instantaneously' to real-time intelligence gained from the UAV's data.

'The Ukrainians have used drones much more tactically on the battlefield than the Russians have. They've been innovative and drones have been real force multipliers in terms of giving the Ukrainians options and the ability to track Russian targets and destroy them,' Dr Jordan tells MailOnline. 

'Ukrainian forces have really evolved with the help of drones, particularly in terms of information gathering and surveillance. Drones have really bolstered Ukraine's war effort.'

Indeed, Krystyna Marcinek, of the American think tank RAND, says drones have allowed Ukrainian soldiers to have 'a situational awareness for multiple missions at the same time along the front line,' meaning they have been able to launch a series of attacks at once.
