Tunnel rat (military)

The tunnel rats were American, Australian and New Zealand soldiers who performed underground search and destroy missions during the Vietnam War.

Later, similar teams were used by the Soviet Army during the Soviet war in Afghanistan, and the Israel Defense Forces.

During the Vietnam War "tunnel rat" became a more or less official specialty for volunteer infantrymen, primarily from Australia, New Zealand and the United States. Their motto was the Latin phrase "Non Gratus Rodentum"—"not worth a rat". Since the 1940s, during the war against the French colonial forces, the Viet Cong had created an extensive underground system of complexes. By the 1960s, there were underground hospitals, training grounds, storage facilities, headquarters and more. The Viet Cong, who were skilled at guerrilla warfare, might stay underground for several months at a time. The tunnels were their territory.

Whenever troops would uncover a tunnel, tunnel rats were sent in to kill any hiding enemy soldiers and to plant explosives to destroy the tunnels. A tunnel rat was equipped with only a standard issue .45 caliber pistol, a bayonet and a flashlight, although most tunnel rats were allowed to choose another pistol with which to arm themselves. The tunnels were very dangerous, with numerous booby traps and enemies lying in wait.

The tunnels presented many potential threats: enemy soldiers manned holes on the sides of tunnels through which spears could be thrust, impaling a crawling intruder. Not only were there human enemies, but also dangerous creatures, such as snakes (including venomous ones, sometimes placed there as living booby traps), rats, spiders, scorpions and ants. Black-Bearded Tomb Bats (Taphozous melanopogon) and Lesser Dawn Bats (Eonycteris spelaea) also roosted in the tunnels, though they were a harmless nuisance if awakened. Often there were flooded U-bends in the tunnels to trap poison gas. Underground, gas could be a very deadly weapon, and a tunnel rat might choose to go into the tunnels wearing a gas mask as it would be impossible to put one on in a narrow tunnel. More often than not, however, a tunnel rat would take his chances without a gas mask, as wearing one made it even harder to see, hear and breathe in the narrow, dark tunnels.
