The emergence of increasingly capable robotic and autonomous systems (RAS) has been recognised as having the potential to become a disruptive wave, raising significant challenges as well as opportunities for militaries. Every major military force has now publicly declared an interest in either developing, utilising or banning RAS. Even world leaders, such as Russian President Vladamir Putin, have issued proclamations regarding its potential impact on the future of warfare. Yet, despite these claims, there have been no documented widescale deployments of weapon systems that one could unequivocally declare to be both robotic and functionally autonomous.
