The paper presents the Virtual Reality (VR) - Augmented Reality (AR) Simulator Kit designed for Call for Fire (CFF) training within the framework of fire support. It describes the system’s modular architecture, the use of mixed reality, voice control, and Artificial Intelligence (AI) based analysis of standardized CFF communication. Pilot validation confirmed the technical functionality of the solution, as well as its ability to objectively assess procedural correctness and monitor reaction time and error rates. Its main contribution lies in linking immersive training with the broader context of fire support command and control. The originality of the paper consists in integrating VR/AR, AI, and analytical evaluation into a single training ecosystem.
