A US Navy sailor used a .50 caliber machine gun to shoot down a small drone during a NATO exercise focused on naval air defense.The sailor, Petty Officer Second Class Brian Diaz, scored a direct hit on the drone with his M2 Browning machine gun.The exercise simulated a real threat scenario faced by warships in the future as drones play an increasing role in naval warfare.The engagement took place during NATO's Formidable Shield 25 exercise, where allies train for air defense scenarios.Diaz also engaged a remote-controlled boat and a flying drone during the exercise, demonstrating the ship's weapons systems.Shooting down small drones can be challenging due to their size and erratic movements, making Diaz's successful hit significant.The US Navy is integrating counter-drone training into its planning, learning from conflicts like the Red Sea where drones were used against vessels.Houthis in Yemen used one-way attack drones, highlighting the evolving threat posed by drones in naval operations.Drones, including quadcopters, are considered a potential threat to warships due to their ability to carry ordnance and cause damage.While quadcopters may not disable a destroyer, they could still pose dangers to personnel and equipment, necessitating vigilance against such threats.
