The machines and weapons designed to fight the 'Full On' Heavy Metal wars of the 20th century now face a grim challenge, they must adapt or die. Today, the armies of the world operate in 'Low Burn' guerrilla conflict - often in urban environments where civilian casualties must be avoided at all costs. Are today's relatively 'low tech' enemies gaining ground against the cutting edge military might of the West? How can the designers and manufacturers of 21st Century War Machines counter these unsophisticated but very real threats? Renowned military analyst Simon Pearson guides this 5 part series through the origins of Main Battle Tanks, Attack Helicopters, Missiles, Fighter and Bomber Aircraft and Artillery right through to today's state of the art 'Digital Battlefield'. We hear from the makers and the users of the latest military technology whilst also investigating the history and the future of man and machine in combat. Supported by spectacular footage and intricate 3D Computer Generated Images, this series poses and answers many questions on this extremely topical subject.
