According to the developer, more than 40% of frontline engagements now involve FPV drones, and the veterans who helped build the trainer name one countermeasure as the most effective at close range: a shotgun loaded with buckshot, with five rounds or more in the magazine.
The difficulty is the shot itself. The target is 7 to 10 inches across, changes speed and direction, and has to be led. Shooters must learn to hold fire until the drone is inside 50 to 60 metres and to manage their ammunition while more drones come in. Under stress, that only works when it has been done many times before.
The trainer is developed together with military instructors and combat veterans who have countered FPV drones themselves, for anyone who may find himself within 30 km of the front line.
