An intrepid reporter Ghaith Abdul-Ahad has written this article:http://www.guardian.co.uk/world/2012...rs-joining-war

Interesting to note the differences between the Jihadists and the Syrians, although that does not explain the Jihadist's attrition rate completly.

He also has a PBS documentary, this was on the PBS website, but didn't load in the UK and I accessed it via:http://www.enduringamerica.com/home/...-frontlin.html

There is a second historical documentary, which is good round-up too.
