K-9 units were used to find snipers during the Vietnam War. These dogs are amazing!

Canine units are an invaluable part of police forces, security teams, rescue teams, and the army.. They find people in collapsed rubble, and sniff out bombs. Incredibly, during the Vietnam War, they even sniffed out snipers.

Snipers shoot from hidden positions, and if soldiers are able to locate those positions, they can often neutralize the threat. These trained dogs can determine the direction of the sound of the bullet, and will lie down with their heads pointed at the origin of the gunshot.
