The Russia-Ukraine war emphasised how digital technology and the information domain increasingly integrate into modern battlefields. The military strategy began using Robotic and Autonomous Systems (RASs) to enhance tactical and strategic advantages over conventional weaponry and kinetic military action. Evolution in these circumstances increased dependence on cyberspace, algorithms, automation, and robots, creating new opportunities and challenges. Using military RASs in physical warfare can provide relevant operational advantages and open new vulnerabilities, increasing a system attack surface. This research examines military RAS cybersecurity threats, potential vulnerabilities affecting the attack surface, and the importance of responsible and precise technical innovation.
