Chapter 27: XR in Military, Defense, and Security Applications

Abstract:

Extended Reality (XR) in military, defense, and security dramatically boosts training, planning, and operations through immersive simulations, virtual collaboration, and enhanced situational awareness, replacing costly live exercises with realistic, AI-driven scenarios for combat, maintenance, and medical training, while also improving mental health support for personnel. Key applications include digital twins for equipment, AI-powered adaptive training, AR overlays for real-world data, and virtual environments for tactics, creating smarter, faster, and more cost-effective defense capabilities. 
Key Applications
  • Training & Simulation: Hyper-realistic, immersive training for combat, first aid, and complex missions (e.g., drone operation, missile defense) without live assets, cutting costs and risks.
  • Mission Planning & Operations: AR overlays provide real-time data on troop locations, threats, and terrain; virtual collaboration tools allow remote mission rehearsal.
  • Maintenance & Repair: Digital twins of complex equipment (like fighter jets) allow for virtual inspection and repair training, improving readiness and reducing downtime.
  • Decision Support: AI-integrated XR platforms offer real-time data visualization and decision support, compressing decision cycles.
  • Mental Health: VR exposure therapy helps treat PTSD in veterans and active personnel by simulating trauma triggers in a controlled setting. 
Core Benefits
  • Cost & Logistics Reduction: Replaces expensive physical assets and logistical challenges with digital simulations.
  • Enhanced Readiness: Prepares forces for diverse and complex scenarios, improving adaptability and responsiveness.
  • Faster Innovation: Rapid experimentation with new tactics in virtual environments.
  • Improved Efficiency: AI-driven scenarios and personalized feedback standardize and accelerate learning. 
Technology Integration
  • XR + AI: Combines immersive visuals with AI for dynamic, adaptive scenarios and intelligent mentorship.
  • Digital Twins: Interactive 3D models of equipment for hands-on practice
  • AR/VR/MR: Utilizes various XR forms for different needs, from full immersion (VR) to real-world data overlays (AR). 
Future Outlook
XR is moving beyond gaming into a fundamental tool for defense, requiring collaboration between defense organizations, vendors, and researchers to realize its full potential for more agile and capable forces.
