Executive Outcomes was the title of the most successful private army of modern times. In Angola, Sierra Leone and Papua New Guinea, it stepped in while the UN revealed itself as little more than a debating society. But the motives of this mercenary army are open to question: was it more interested in protecting Sierra Leone's diamond mines than the people caught up in a savage guerilla war? Journalist Jim Hooper followed Executive Outcomes on operations all over Africa and in this book reveals the story of a mercenary army in action.
