HoloTerra turns mission plans into dynamic, terrain-anchored rehearsals that let warfighters physically run multiple courses of action before execution. Routes, objectives, threats, UAS tracks, and fused sensor data are placed directly into the operating environment, while AI-driven adversaries, role players, and mission assistants respond to warfighter decisions in real time. As teams move, communicate, and act, the rehearsal branches with them—exposing decision points, testing alternative courses of action, and helping commanders understand how a mission may unfold under changing conditions.
