Ross Kemp is what might be termed as a 'sham-rock'. And I don't mean he is lucky.
To be honest, I don't think the soldiers wanted him there. There's one scene, near the end of the series, where you can tell that not one of them would speak to him unless they had to.
It was a good series though overall, though. I'm trying to think of another one I saw that was also as good - may have been Panorama on the BBC.
