On this week’s Sitrep we delve into the minds of foreign fighters. What makes someone who’ served in the military or is just a civilian want to go and fight in a conflict overseas, such as Ukraine. We’ll hear from Emile Ghessen has met many of them, he was a Royal Marine but is now a documentary film maker and is in Kyiv.

We’ll also be discussing war crimes….there have been a lot of allegations made against Russian forces, But, what actually constitutes a war crime and how easy are they to pursue?

We’ll look again at the recent Defence Review…is it now out of date given the change of emphasis because of Ukraine?
