"We're like a red rag to the enemy. Because we're taking the war to their territory so that they feel it too," the Ukrainian soldier says, as his unit scramble to assemble long-range drones for launch at Russia.

Ukraine has been intensifying its deep strikes like this for several weeks, targeting oil export facilities, in particular, like never before.

Now, in a rare interview, the commander of all Ukraine's unmanned systems has told the BBC such attacks will escalate and claimed his drone forces are also holding back Russia's advance along the frontline by killing a record number of soldiers.

"1,500 to 2,000km (930-1,240 miles) inside Russian territory is no longer the 'peaceful rear'," Robert Brovdi warns. "The freedom-loving Ukrainian 'bird' flies there whenever and wherever it wants."
