The Origins of Military Losses

Classified US documents purportedly about the war in Ukraine have been circulating online, in what's been called by some the most damaging intelligence disaster in a decade.

It is believed some of the documents may have doctored - but the US has admitted they are likely to be authentic. So how does America deal with a security leak relating to war? And how can we tell what's true or not?

On the Sky News Daily, Leah Boleto speaks to Jack Taylor from Sky's data and forensics unit about the verification of leaked documents. She's also joined by security and defence expert Michael Clarke to discuss what impact the leak could have in the conflict.
