Finland Tests Varjo XR-4 Mixed Reality Headsets to Train Soldiers Against Small FPV Drones

The Finnish Defence Forces Innovation Unit and Varjo are piloting virtual counter-drone training with a brigade-level military unit using XR-4 headsets. Announced on October 29, the collaboration aims to let soldiers practise detecting and responding to small FPV threats repeatedly without consuming live drones or other physical training resources. The partners say the headset’s visual resolution can represent a five-inch drone at realistic engagement distances, addressing the difficulty of displaying small aerial targets in simulation. The participating unit, simulator software, headset quantity, cost and trial duration were not disclosed, and the project remains a pilot rather than fleet-wide procurement.
