They were young, they were tough and they were everywhere. They were both the backyard builders and the frontline troops in Australia's war against the Taliban.This is the powerful story of the sappers, the Army engineers in Afghanistan whose raw courage and skills were inspired by the original Australian Tunnel Rats of the war in Vietnam. These Tunnel Rats of Afghanistan have rooted out the enemy from deep inside their caves and mountain hideouts, have defused thousands of improvised explosive devices (the booby traps and landmines of this most recent of wars), built bridges and schools to win a war of hearts and minds, and fought side by side with special forces commandos and SAS troops. They, too, lost a disproportionate number of their comrades and many returned home with the devastating baggage of war, post-traumatic stress disorder.Inspiring and action packed, this is the story of a special breed of soldier operating in a modern war against an enemy with medieval morals . . . and bombs triggered by mobile phones. It is a story that connects the unsung heroes of Vietnam with the modern heroes of Afghanistan.
