The tunnel rats were courageous soldiers who performed underground search and destroy missions during the Vietnam War.  American and Australian troops uncovered the enemy's intricate network of tunnels while conducting larger operations. Tunnel rats were tasked with gathering intelligence within them, and killing or capturing their occupants--often in conditions of close combat. CW Bowman, Gerry Schooler and Art Tejeda spent days maneuvering through the tunnel complexes clearing and destroying lethal booby-traps.
