Understanding the impact of swarm dynamics on land defenses means evaluating the complex behaviors exhibited by groups of autonomous or semi-autonomous entities. This paper explores the critical role of specific technologies' AI, TSN, Sensor Fusion, Autonomous Systems, and Cybersecurity ' in enabling effective swarm operations within JADC2 to detect, analyze, and respond to swarm threats in real-time across diverse platforms and domains and ensure compatibility with existing command and control infrastructure. By effectively addressing the challenges to ground vehicles while exploiting the opportunities presented by swarm operations requires a holistic understanding of swarm dynamics and the integration of advanced technologies and adaptive command and control systems within the JADC2 framework.
