Meet South Korea’s mobile air defense killer the K30 Biho. This system is armed with twin 30mm autocannons, firing up to 1,200 rounds per minute combined. It can engage targets at a range of around 3 kilometers, perfect for low-flying drones, helicopters, and aircraft. The onboard radar can detect threats up to 15–20 kilometers away, even in poor weather or darkness. Mounted on a tracked armored vehicle, it can move at speeds of 60 km/h, keeping up with frontline troops.
