Radio 1's Greg James hears from British troops who served in Afghanistan as they contrast their experiences with those who fought in World War One. Mixing new interviews from Afghanistan veterans with archive of those who endured the trenches, this story brings out the universality of experience of going to war: the joining up, the camaraderie, the killing, the trauma and the loss, as well as asking if all wars change those who fight in them in similar ways.
