Although other weapons were involved such as aeroplanes gas and machine guns nevertheless the BEF itself thought of the tank as the touchstone or benchmark of mechanical warfare. The debate over mechanical warfare versus traditional infantry warfare continued through 1918 with a growing number of converts to the mechanical thesis. The marks of a scientific law are conformity to reason uniformity and certainty scientific law is a reasoned body of principles for the administration of justice and its antithesis is a system of enforcing magisterial caprice however honest and however much disguised under the name of justice or equity or natural law. As international law developed over the centuries sovereigns and their military commanders began to place voluntary limits on their right to conduct warfare. Most of these voluntary limitations developed because they served a tactical purpose but others were based on a moral view of warfare and that some actions were not right even in open hostilities. This book presents an overview of the current and future of judicial system in mechanical warfare.
