Today, with the advent of unmanned systems, military hopes are attached to the idea that battles can be fought with soldiers pressing buttons in distant command centres. However, soldiers must now be highly trained, super strong and have the intelligence and mental capacity to handle the highly complex and dynamic military operating environment. This book provides the first comprehensive and unifying analysis of the moral, legal and social questions concerning military human enhancement, with a view toward developing guidance and policy that may influence real-world decision making.
