4. Snakes As Military Weapons

During the Vietnam War, the Viet Cong army used tunnels to travel across places as a way of avoiding American air attacks. When the Americans came to know of this they sneaked a few deadly rats into the tunnels to hunt down the enemies and harm them. In return the Viet Cong filled the tunnels that the Americans used, with bamboo vipers. The serpents were called “one-step” or “two-step” snakes because, when bitten, the victim would walk slower and slower until he’d dropped dead. These vipers were kept hidden inside hollow bamboo stick.
