I used this book to help me write a mini-dissertation on the use of Private Military Companies (PMCs) and the consequence of this for the foreign policies of different countries.
It is written in a way that would be unpalatable for many academics, but this (for me, at least) is no shortcoming. Many academics, such as D Avant and P Singer, have written extensively on this subject but their works can be criticised for typical academic 'ivory tower' syndrome. Robert Pelton however has been out on the ground, in often dangerous environments, gaining valuable interviews from many colourful characters. Combined with a engaging writing style, this book is both readable and educating.
I'd recommend this book for anyone with a passing interest in PMCs, although for students/academics I'd say it is best used alongside works such as those by Avant and Singer in order to set the context within the academic debate. Also since the publication of this book, PMCs have evolved into a very different beast from what they were at the immediate aftermath of the invasion of Iraq - therefore the picture it paints is a little out of date.
