The US military's Boeing HEL MD truck automatically shoots lasers at flying targets like drones and mortar rounds. But unlike their sci-fi cousins, these lasers aren't green glowing lines; they are invisible and silent. The vehicle's operators are often unaware when the laser is firing (unless a drone mysteriously falls from the sky.) To solve this problem, HEL MD will play laser sound effects for the human operators, and they will sound very similar to the sci-fi laser sounds of Star Wars and Star Trek.
