Ukraine has amassed so much battlefield footage from drones that it would take more than 200 years to watch. Now it’s using that footage, with machine learning, to teach drones to become more lethal.

Simon Newton explains how the country has made breakthroughs that allow the devices to identify not only potential targets, but also their most vulnerable spots.

The work could also have benefits for the UK with talk that massive pool of training data could be shared with allies.

But does this put us on an unstoppable path to machines making life and death decisions on the battlefield? Dr. Matthew Powell, from the RAF College Cranwell, explains the practical and ethical dilemmas.
