To a person who has a love of dogs and an admiration for their uses in war and law enforcement, this book provides a fascinating insight into the history of dogs and the current day employment of them.From Babylonian mastiff-type war dogs with spiked collars, to modern kitted-out military dogs highly trained to detect explosives, dogs have long been a soldier?s best friend. Nigel Allsopp, a highly experienced dog handler in both military and civilian police arenas, details how the incredible abilities of dogs are indispensable in military, para-military and police operations. Country by country, he details how dogs were used and trained in the past and present for patrolling, guarding, search and rescue, parachuting and, perhaps most importantly in today?s political climate, detection of explosives. Allsopp?s ability to not only write this information with real passion and expertise, but also to gain permission to print highly sensitive materials from nearly 50 nations, makes this the most authoritative and comprehensive book available on the subject. Cry Havoc galvanises the notion that, despite technological advances in warfare, dogs will continue to be one of the most useful tools of support in every nation?s security interests. The future will continue to hear the call ?Cry Havoc - and let loose the dogs of war!?
