HMS Diamond has been sent to the Red Sea after missile and drone attacks against British owned cargo vessels, and RAF spy-planes have been deployed to search for hostages held in Gaza.

Professor Michael Clarke and former Royal Navy commander Tom Sharpe explain what these assets and personnel can achieve, the limitations & risks of their missions, and the possibility of more UK military capability joining them.

Sitrep also looks at another big deployment much closer to home, a new Royal Navy task group trying to protect critical undersea power and data cables, alongside European allies.

And does military history repeat itself, or just rhyme? Kate talks to military historian Lucy Betteridge-Dyson, General Sir Mike Jackson and General Lord Richards about how the study of past conflicts shapes the wars of today.
