The tunnel rats were American, Australian, New Zealander, and South Vietnamese soldiers who performed underground search and destroy missions during the Vietnam War.
Later, similar teams were used by the Soviet Army during the Soviet–Afghan War and by the Israel Defense Forces in campaigns in the Middle East.
During the Vietnam War, "tunnel rat" became an unofficial specialty for volunteer combat engineers [1] and infantrymen from the Australian Army and the U.S. Army who cleared and destroyed enemy tunnel complexes. Their motto was the tongue-in-cheek Latin phrase Non Gratum Anus Rodentum ("not worth a rat's ass"). [2]
In the early stages of the war against the French colonial forces, the Viet Minh created an extensive underground system of tunnels, which was later expanded and improved by the Viet Cong. By the 1960s, the tunnel complexes included hospitals, training areas, storage facilities, headquarters, and barracks. These diverse facilities, coupled with sophisticated ventilation systems, allowed VC guerrillas to remain hidden underground for months at a time.[ citation needed ]
During the Vietnam War, ANZUS troops uncovered a great number of enemy tunnels while patrolling or conducting larger operations. The men of the 3 Field Troop, an Australian combat engineering unit that served in Vietnam from 1965 to 1966, have made a convincing argument that they were the first allied troops to enter the tunnels. [3] Tunnel rats were given the task of destroying them, gathering intelligence within them, and killing or capturing their occupants—often in conditions of close combat. Typically, a tunnel rat was equipped with only a standard issue M1911 pistol or M1917 revolver, [4] a bayonet, a flashlight, and explosives.
Many tunnel rats reportedly came to dislike the intense muzzle blast of the relatively large .45 caliber round, as the .45's loud report could often leave one temporarily deaf when fired in a confined space. [5] Consequently, some preferred to clear tunnels armed with a .38 Special revolver equipped with a sound suppressor [6] and other non-standard weapons. [7] "A few of the OSS-ordered World War II era suppressed High Standard HD .22 automatics made their way into Tunnel Rat hands. But these weapons were very few in number and wanted by a number of other special units. Personal weapons were used by the rats, ranging from .25 caliber automatics to sawn-off shotguns." [5]
Besides enemy combatants, the tunnels themselves presented many potential dangers to tunnel rats. Sometimes they were poorly constructed and they would simply collapse. Tunnels were often booby trapped with hand grenades, anti-personnel mines, and punji sticks. The VC would even use venomous snakes (placed as living booby traps). Rats, spiders, scorpions, and ants also posed threats to tunnel rats. Bats also roosted in the tunnels, although they were generally more of a nuisance than a threat. Tunnel construction occasionally included anti-intruder features such as U-bends that could be flooded quickly to trap and drown the tunnel rat. Sometimes poison gases were used. A tunnel rat might therefore choose to enter the tunnels wearing a gas mask (donning one within was frequently impossible in such a confined space). According to U.S. tunnel rat veterans, however, most tunnel rats usually went without gas masks because wearing one made it even harder to see, hear, and breathe in the narrow dark passages.[ citation needed ]
Tunnel rats were generally men of smaller stature (165 cm (5 ft 5 in) and under), who were able to maneuver more comfortably in the narrow tunnels. [8] Tom Mangold and John Penycate, authors of one of the definitive accounts of tunnel warfare during the Vietnam War, reported that the U.S. tunnel rats were almost exclusively soldiers of European or Hispanic descent, many of whom were Puerto Rican or Mexican American. [9]
By Mangold and Penycate's account, the tunnel rats first garnered public attention in January 1966, after a combined U.S. and Australian operation against the Củ Chi tunnels in Bình Dương Province, known as Operation Crimp. The "Diehards" of the U.S. Army's 1st Engineer Battalion later were tunnel rats during their rotation through the Củ Chi District of South Vietnam in 1969. [9]
In the years since the Vietnam War ended, tunnel rats have suffered from a high percentage of Agent Orange injuries and diseases due to soldiers' exposure to the chemicals on the ground, or that leached from topsoil into the tunnel environment. While in the tunnels, soldiers were breathing air heavily saturated with Agent Orange.[ citation needed ]
Afghanistan features an extensive series of historic tunnels used for transporting water and the "kariz." During the 1979–1989 Soviet war in Afghanistan, such tunnels were used by Mujahideen fighters. The Soviet 40th Army therefore fielded their own tunnel clearance and demolition units, which were given the task of clearing the tunnels of enemy combatants, disarming booby traps, and destroying the underground complexes. [10] According to contemporary accounts, the U.S. Marine Corps and British Royal Marines were involved in similar work in the war in Afghanistan. [11] [12]
SAMOOR (Hebrew : סמור, "weasel"), a formation within Israel's Yahalom elite combat engineer unit, is charged with many of the same missions that tunnel rats performed during the Vietnam War. [13]
The Viet Cong was an epithet to call the communist movement and united front organization in South Vietnam, Laos and Cambodia. Formally organized as and led by the National Liberation Front of South Vietnam, it fought under the direction of North Vietnam against the South Vietnamese and United States governments during the Vietnam War. The organization had both guerrilla and regular army units, as well as a network of cadres who organized and mobilized peasants in the territory the Viet Cong controlled. During the war, communist fighters and some anti-war activists claimed that the Viet Cong was an insurgency indigenous to the South, while the U.S. and South Vietnamese governments portrayed the group as a tool of North Vietnam. It was later conceded by the modern Vietnamese communist leadership that the movement was actually under the North Vietnamese political and military leadership, aiming to unify Vietnam under a single banner.
The Vietnam War involved the People's Army of Vietnam (PAVN) or North Vietnamese Army (NVA), National Liberation Front for South Vietnam (NLF) or Viet Cong (VC), and the armed forces of the People's Liberation Army (PLA), Army of the Republic of Vietnam (ARVN), United States Armed Forces, Republic of Korea Armed Forces, Armed Forces of the Philippines, Royal Thai Armed Forces, Australian Defence Force, and New Zealand Defence Force, with a variety of irregular troops.
The tunnels of Củ Chi are an immense network of connecting tunnels located in the Củ Chi District of Ho Chi Minh City (Saigon), Vietnam, and are part of a much larger network of tunnels that underlie much of the country. The Củ Chi tunnels were the location of several military campaigns during the Vietnam War, and were the Viet Cong's base of operations for the Tết Offensive in 1968.
The Iron Triangle was a 120 square miles (310 km2) area in the Bình Dương Province of Vietnam, so named due to it being a stronghold of Viet Minh activity during the war. The region was under control of the Viet Minh throughout the French war in Vietnam and continued to be so throughout the phase of American involvement in the Vietnam War, despite concerted efforts on the part of US and South Vietnamese forces to destabilize the region as a power base for their enemy, the communist North Vietnamese–sponsored and–directed South Vietnamese insurgent movement, the Viet Cong (VC).
Operation Crimp, also known as the Battle of the Ho Bo Woods, was a joint US-Australian military operation during the Vietnam War, which took place 20 kilometres (12 mi) north of Cu Chi in Binh Duong Province, South Vietnam. The operation targeted a key Viet Cong headquarters that was believed to be concealed underground, and involved two brigades under the command of the US 1st Infantry Division, including the 1st Battalion, Royal Australian Regiment which was attached to the US 173rd Airborne Brigade. Heavy fighting resulted in significant casualties on both sides, but the combined American and Australian force was able to uncover an extensive tunnel network covering more than 200 kilometres, at the cost of 8 Australians and 14 Americans killed and 29 Australians and 76 Americans wounded.
Tunnel warfare is using tunnels and other underground cavities in war. It often includes the construction of underground facilities in order to attack or defend, and the use of existing natural caves and artificial underground facilities for military purposes. Tunnels can be used to undermine fortifications and slip into enemy territory for a surprise attack, while it can strengthen a defense by creating the possibility of ambush, counterattack and the ability to transfer troops from one portion of the battleground to another unseen and protected. Also, tunnels can serve as shelter from enemy attack.
The battle of Nam Đông took place from July 5–6, 1964 during the Vietnam War, when the Viet Cong (VC) and People's Army of Vietnam (PAVN) attacked the Nam Đông CIDG camp in an attempt to overrun it. During the battle, 57 South Vietnamese defenders, two Americans, an Australian Military advisor, and at least 62 attackers were killed.
The 5th Infantry Regiment is an infantry regiment of the United States Army that traces its origins to 1808.
Ruppert Leon Sargent was a United States Army officer and a recipient of America's highest military decoration—the Medal of Honor—for his actions in the Vietnam War.
Củ Chi is a rural district of Ho Chi Minh City, Vietnam.
The Battle of Gang Toi was fought during the Vietnam War between Australian troops and the Viet Cong. The battle was one of the first engagements between the two forces during the war and occurred when A Company, 1st Battalion, Royal Australian Regiment struck a Viet Cong bunker system defended by Company 238 in the Gang Toi Hills, in northern Bien Hoa Province. It occurred during a major joint US-Australian operation codenamed Operation Hump, involving the US 173rd Airborne Brigade, to which 1 RAR was attached. During the latter part of the operation an Australian rifle company clashed with an entrenched company-sized Viet Cong force in well-prepared defensive positions. Meanwhile, an American paratroop battalion was also heavily engaged in fighting on the other side of the Song Dong Nai.
Vịnh Mốc is a tunnel complex in Quảng Trị, Vietnam. During the Vietnam War it was strategically located on the border of North Vietnam and South Vietnam. The tunnels were built to shelter people from the intense bombing of Son Trung and Son Ha communes in Vinh Linh county of Quảng Trị Province in the Vietnamese Demilitarized Zone.
VC and PAVN battle tactics comprised a flexible mix of guerrilla and conventional warfare battle tactics used by Viet Cong (VC) and the North Vietnamese People's Army of Vietnam (PAVN) to defeat their U.S. and South Vietnamese (GVN/ARVN) opponents during the Vietnam War.
Tunnel Rats, also known as 1968 Tunnel Rats, is a 2008 German-Canadian war suspense film written and directed by Uwe Boll. The film is based on the factual duties of tunnel rats during the Vietnam War. In a documentary for the film, Boll revealed the film did not have a script, and instead the actors improvised their lines.
Hố Bò woods are located in Bình Dương Province 20 km north of Củ Chi, 4 km to the west of the Iron Triangle and the Saigon River and some 56 km northwest of Saigon. The woods consist of rubber plantations, sparse to dense woods, and open rice paddies with some extremely large dikes, some 1–2 metres high. The woods were used by the Viet Cong (VC) as a base area during the Vietnam War.

Colonel Alexander Hugh "Sandy" MacGregor, is an Australian author and former army officer. From 1989 until 2015, MacGregor ran workshops and seminars, teaching people in the public, educational and private sectors on how to "use the power of the subconscious mind."
The Liberation Army of South Vietnam was an irregular military force established by the Workers' Party of Vietnam in 1961 in South Vietnam as the armed wing of the Viet Cong. In 1962, the People's Revolutionary Party of South Vietnam separated from the Workers' Party of Vietnam in terms of external appearance, openly directing the Liberation Army's military. Politically, the South Vietnamese Liberation Army was under the direction of the National Front for the Liberation of South Vietnam and the Provisional Revolutionary Government of the Republic of South Vietnam. The military forces from the North to the South of Vietnam, although collectively known as the Liberation Army of South Vietnam, still use the unit names, military badges and War flag of the Vietnam People's Army.
In transport, tunnels can be connected together to form a tunnel network. These can be used in mining to reach ore below ground, in cities for underground rapid transit systems, in sewer systems, in warfare to avoid enemy detection or attacks, as maintenance access routes beneath sites with high ground-traffic such as airports and amusement parks, or to extend public living areas or commercial access while avoiding outdoor weather.
