From Ukraine and Russia to Gaza and Sudan, drones have become a key weapon of war. Which companies are making them, and profiting from this rapidly expanding but controversial sector within the defence industry?

We hear from a woman in Ukraine who used to own a flower shop in Kyiv, but who is now making drones to send to the front-line; and we hear from a Russian who left his homeland as a teenager and now, from Australia, is developing the technology that helps protect Ukraine from Russian attack.

And a former Norwegian paratrooper tells us how he can help protect soldiers from drones.
