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.
Nearly all United States-allied forces were armed with U.S. weapons including the M1 Garand, M1 carbine, M14 rifle, and M16 rifle. The Australian and New Zealand forces employed the 7.62 mm L1A1 Self-Loading Rifle as their service rifle, with the occasional use of the M16 rifle.
The PAVN, although having inherited a variety of American, French, and Japanese weapons from World War II and the First Indochina War (aka French Indochina War), were largely armed and supplied by the People's Republic of China, the Soviet Union, and its Warsaw Pact allies. Further, some weapons—notably anti-personnel explosives, the K-50M (a PPSh-41 copy), and "home-made" versions of the RPG-2—were manufactured in North Vietnam. By 1969 the US Army had identified 40 rifle/carbine types, 22 machine gun types, 17 types of mortar, 20 recoilless rifle or rocket launcher types, nine types of antitank weapons, and 14 anti-aircraft artillery weapons used by ground troops on all sides. Also in use, mostly by anti-communist forces, were the 24 types of armored vehicles and self-propelled artillery, and 26 types of field artillery and rocket launchers.
During the early stages of their insurgency, the Viet Cong mainly sustained itself with captured arms (often of American manufacture) [1] or crude, self-made weapons (e.g. copies of the US Thompson submachine gun [2] and shotguns made of galvanized pipes). [3] [4] Most arms were captured from poorly defended ARVN militia outposts. [5]
Communist forces were principally armed with Chinese and Soviet weaponry though some VC guerrilla units were equipped with Western infantry weapons either captured from French stocks during the first Indochina war, such as the MAT-49, or from ARVN units or requisitioned through illicit purchase.
By Autumn of 1967, all Viet Cong battalions were reequipped with arms of Soviet design such as the AK-47 battle rifle and the RPG-2 anti-tank weapon. [6] Their weapons were principally of Chinese [7] or Soviet manufacture. [8] The period up to the conventional phase in the 1970, the Viet Cong and NVA were mostly limited to mortars, recoilless rifles, and small-arms and had significantly lighter equipment and firepower relative to the US arsenal, relying on ambushes, with superior stealth, planning, marksmanship, and small-unit tactics to face the disproportionate US technological advantage. [9]
Many divisions within the NVA would incorporate armoured and mechanised battalions including the Type 59 tank, BTR-60, Type 60 artillery, and rapidly altered and integrated new war doctrines following the Tet Offensive into a mobile combined-arms force. [10] The North Vietnamese had both amphibious tanks (such as the PT-76) and light tanks (such the Type 62) used during the conventional phase. Experimental Soviet equipment started being used against ARVN forces at the same time, including Man-portable air-defense system SA-7 Grail and anti-tank missiles including the AT-3 Sagger. [11] By 1975, they had fully transformed from the strategy of mobile light-infantry and using the people's war concept used against the United States. [10]
The American M16 rifle and XM177 carbine, which both replaced the M14, were lighter and considered more accurate than the AK-47 but in Vietnam was prone to "failure to extract", in which the spent cartridge case remained stuck in the chamber after a round was fired, preventing the next round from feeding and jamming the gun.[ citation needed ] This was ultimately traced to an inadequately tested switch in propellants from DuPont's proprietary IMR 4475 to Olin's WC 846, that Army Ordnance had ordered out of concern for standardization and mass production capacity.[ citation needed ]
The heavily armored, 90 mm gun M48A3 'Patton' tank saw extensive action during the Vietnam War and over 600 were deployed with U.S. forces. They played an important role in infantry support though there were a few tank versus tank battles. The M67A1 flamethrower tank (nicknamed the Zippo) was an M48 variant used in Vietnam. The use of this euphemistically nicknamed tank should not be confused with the widespread use of actual Zippo lighters to burn villages, which gave rise to the nickname of "Zippo squads". (Far from all such squads fielded the tank.) The Zippo nickname was also applied to man-portable flamethrowers. [13] Artillery was used extensively by both sides but the Americans were able to ferry the lightweight 105 mm M102 howitzer by helicopter to remote locations on quick notice. [14] [15] With its 17-mile (27 km) range, the Soviet 130 mm M-46 towed field gun was a highly regarded weapon and used to good effect by the PAVN. It was countered by the long-range, American 175 mm M107 Self-Propelled Gun (nicknamed Miller). [16]
The United States had air superiority, though many aircraft were lost to surface-to-air missiles and anti-aircraft artillery. U.S. airpower was credited with breaking the siege of Khe Sanh and blunting the 1972 Easter Offensive against South Vietnam. At sea, the U.S. Navy had the run of the coastline, using aircraft carriers as platforms for offshore strikes and other naval vessels for offshore artillery support. Offshore naval fire played a pivotal role in the Battle of Huế in February 1968, providing accurate fire in support of the U.S. counter-offensive to retake the city. [17]
The Vietnam War was the first conflict that saw wide-scale tactical deployment of helicopters. [18] The Bell UH-1 Iroquois nicknamed "Huey" was used extensively in counter-guerilla operations both as a troop carrier and a gunship. [15] In the latter role it was outfitted with a variety of armaments including M60 machine guns, multi-barrelled 7.62 mm Miniguns and unguided air-to-surface rockets. [15] The Hueys were also successfully used in MEDEVAC and search and rescue roles. [15] Two aircraft which were prominent in the war were the AC-130 "Spectre" Gunship and the UH-1 "Huey" gunship. The AC-130 was a heavily armed ground-attack aircraft variant of the C-130 Hercules transport plane; it was used to provide close air support, air interdiction and force protection. The AC-130H "Spectre" was armed with two 20 mm M61 Vulcan cannons, one Bofors 40 mm autocannon, and one 105 mm M102 howitzer. The Huey is a military helicopter powered by one turboshaft engine, and about 7,000 UH-1 aircraft saw service in Vietnam. At their disposal ground forces had access to B-52 and F-4 Phantom II and others to launch napalm, white phosphorus, tear gas and chemical weapons as well. [19] The aircraft ordnance used during the war included precision-guided munition, cluster bombs, a thickening–gelling agent generally mixed with petroleum or a similar fuel for use in an incendiary device, initially against buildings and later mostly as an anti-personnel weapon that sticks to skin and can burn down to the bone.
The Claymore M18A1, an anti-personnel mine, was widely used. It is command-detonated, directionally shooting 700 steel pellets into the kill zone.
Shotguns were used as an individual weapon during jungle patrol; infantry units were authorized a shotgun by TO&E (Table of Organization & Equipment). Shotguns were not general issue to all infantrymen, but were select issue weapons, such as one per squad, etc.

In addition to cargo-carrying and troop transport roles, many of these vehicles were also equipped with weapons and sometimes armor, serving as "gun trucks" for convoy escort duties. [216]
The geographically dispersed nature of the war challenged existing military communications. From 1965 to the final redeployment of tactical units, numerous communications-electronics systems were introduced in Vietnam to upgrade the quality and quantity of tactical communications and replace obsolete gear:

The PAVN and the Southern communist guerrillas, the Viet Cong (VC) as they were commonly referred to during the war, largely used standard Warsaw Pact weapons. Weapons used by the PAVN also included Chinese Communist variants, which were referred to as CHICOM's by the US military. Captured weapons were also widely used; almost every small arm used by SEATO may have seen limited enemy use. During the early 1950s, US equipment captured in Korea was also sent to the Viet Minh.
Field artillery rockets were often fired from improvised launchers, sometimes a tube fixed with bamboo. [96]

The Army of the Republic of Vietnam composed the ground forces of the South Vietnamese military from its inception in 1955 to the Fall of Saigon on 30 April 1975. At the ARVN's peak, an estimated 1 in 9 citizens of South Vietnam were enlisted, composed of Regular Forces and the more voluntary Regional Forces and the Popular Force militias. It is estimated to have suffered 1,394,000 casualties during the Vietnam War.
The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher that fires a 40×46mm grenade, which uses what the US Army calls the High-Low Propulsion System to keep recoil forces low, and first appeared during the Vietnam War. Its distinctive report has earned it colorful nicknames, such as "Thumper", "Thump-Gun", "Bloop Tube", "Big Ed", "Elephant Gun", and "Blooper" among American soldiers as well as "Can Cannon" in reference to the grenade size; Australian units referred to it as the "Wombat Gun". The M79 can fire a wide variety of 40 mm rounds, including explosive, anti-personnel, smoke, buckshot, flechette, and illumination. While largely replaced by the M203, the M79 has remained in service in many units worldwide in niche roles.
The Colt Automatic Rifle-15 or CAR-15 is a family of M16 rifle–based firearms marketed by Colt in the 1960s and early 1970s. However, the term "CAR-15" is most commonly associated with the Colt Commando ; these select-fire carbines have ultrashort 10.5-inch (270 mm) and 11.5-inch (290 mm) barrels with over-sized flash suppressors.
The Type 11 light machine gun was a light machine gun used by the Imperial Japanese Army in the interwar period and during World War II. Adopted as the Imperial Japanese Army's first light machine gun, the Type 11 was designed by Kijirō Nambu and had certain similarities to the Hotchkiss series of machine guns. It had an unusual feed system which required five round clips to be dropped into a hopper, this held up to a total of six clips and each round was oiled as it was fed into the chamber. Despite good overall performance, this feed system was prone to collect dirt and grit which would jam the weapon while in use. It was issued to troops in 1922 and saw extensive service as a squad weapon until 1945.
The Type 96 light machine gun was a light machine gun used by the Imperial Japanese Army in the interwar period and in World War II. It was first introduced in 1936, and fires the 6.5×50mm Arisaka from 30-round top-mounted magazines. A combination of unimpressive ballistic performance and a lack of reliability caused the Imperial Japanese Army to try to replace the Type 96 with the Type 99 light machine gun, though both saw major usage until the end of the war.
The RPG-2 is a man-portable, shoulder-fired anti-tank weapon that was designed in the Soviet Union. It was the first successful anti-tank weapon of its type, being a successor to the earlier and unsuccessful rocket-propelled grenade RPG-1.
The XM148 was an experimental 40 mm grenade launcher developed by Colt Firearms as the CGL-4. Colt manufactured the launcher for field testing during the Vietnam War era. After problems with the experimental design were discovered, the XM148 was replaced by AAI Corporation's conceptually similar M203 design, which became the primary grenade launcher used by the US armed forces and others until its ongoing replacement with the M320.
The Type 89 grenade discharger, inaccurately and colloquially known as a knee mortar by Allied forces, is a Japanese grenade launcher or light mortar that was widely used in the Pacific Theater of World War II. It got the nickname the "knee mortar" because of an erroneous Allied belief that these launchers could be fired by propping its plate against the leg. However, anyone trying to fire it this way would receive a severe bruise from its hefty recoil.
The M20 recoilless rifle is a U.S. 75 mm caliber recoilless rifle T21E12 that was used during the last months of the Second World War and extensively during the Korean War. It could be fired from an M1917A1 .30 caliber machine gun tripod, or from a vehicle mount, typically a Jeep. Its shaped charge warhead, also known as HEAT, was capable of penetrating 100 mm of armor. Although the weapon proved ineffective against the T-34 tank and most other tanks during the Korean War, it was used primarily as a close infantry support weapon to engage all types of targets including infantry and lightly armored vehicles. The M20 proved useful against pillboxes and other types of field fortifications.
The Type Chiang Kai-shek rifle, also known as the Generalissimo rifle, and Type 24 (二四式), named after the Chinese Generalissimo Chiang Kai-shek, was a Chinese-made copy of the German Standardmodell rifle, the forerunner of the Karabiner 98k. Preproduction of the Chiang Kai-shek rifle started in 1935. It was designated the Type 79 by the Chinese Communists.
The Vietnamese National Army was the State of Vietnam's military force created shortly after the Élysée Accords, where the State of Vietnam was recognized by France as an independent country ruled by Vietnamese Emperor Bảo Đại. It was commanded by Vietnamese General Hinh and was loyal to Bảo Đại. The VNA fought in joint operations with the French Union's French Far East Expeditionary Corps (CEFEO) against the communist Việt Minh forces led by Ho Chi Minh. Different units within the VNA fought in a wide range of campaigns including the Battle of Nà Sản (1952), Operation Hautes Alpes (1953), Operation Atlas (1953) and the Battle of Dien Bien Phu (1954).
The Army of the Republic of Vietnam Special Forces (Vietnamese: Lực Lượng Đặc Biệt Quân Lực Việt Nam Cộng Hòa, or LLDB were the elite military units of the Army of the Republic of Vietnam. Following the establishment of the Republic of Vietnam in October 1955, the Special Forces were formed at Nha Trang in February 1956. During the rule of Ngô Đình Diệm, the Special Forces were run by his brother, Ngô Đình Nhu, until both were assassinated in November 1963 in a coup. The Special Forces were disbanded in 1975 when South Vietnam ceased to exist after the Fall of Saigon.
The Cambodian Civil War was a military conflict that pitted the guerrilla forces of the Maoist-oriented Communist Party of Kampuchea and the armed and security forces of the Nonaligned Kingdom of Cambodia from 1967 to 1970, then between the joint Monarchist, Maoist and Marxist-Leninist National United Front of Kampuchea alliance and the pro-western Khmer Republic from 1970 to 1975. Main combatants comprised:
The Salvadoran Civil War was a military conflict that pitted the guerrilla forces of the left-wing Marxist-oriented Farabundo Marti National Liberation Front (FMLN) against the armed and security forces loyal to the military-led conservative government of El Salvador, between 1979 and 1992. Main combatants comprised:
The Khmer National Army was the land component of the Khmer National Armed Forces (FANK), the official military of the Khmer Republic during the Cambodian Civil War between 1970 and 1975.
The Laotian Civil War was a military conflict that pitted the guerrilla forces of the Marxist-oriented Pathet Lao against the armed and security forces of the Kingdom of Laos, led by the conservative Royal Lao Government, between 1960 and 1975. Main combatants comprised:
The Republic of Vietnam National Police – RVNP, Police Nationale de la République du Vietnam or Police Nationale for short in French, was the official South Vietnamese national police force from 1962 to 1975, operating closely with the Army of the Republic of Vietnam (ARVN) during the Vietnam War.
The Republic of Vietnam National Police Field Force (Vietnamese: Cảnh Sát Dã Chiến – CSDC), also designated Police de Campagne by the French and variously as National Police Field Force (NPFF), Field Police or Field Force for short by the Americans, was a paramilitary élite branch of the Republic of Vietnam National Police (Vietnamese: Cảnh Sát Quốc Gia – CSQG). Active during the Vietnam War, the CSDC operated closely with the Army of the Republic of Vietnam (ARVN) and the American Central Intelligence Agency (CIA) from 1966 to 1975.
The Liberation Army of South Vietnam, also recognized as the Liberation Army, was an irregular and regular military force established by the Workers' Party of Vietnam in 1961 in South Vietnam as the nominal armed wing of the National Liberation Front and largely operated as a proxy of the existing People's Army of Vietnam. 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.
The Hurricane Aircat was an airboat used as a riverine patrol boat by the US Army and South Vietnamese Army (ARVN) during the Vietnam War. It was used to conduct various counterinsurgency (COIN) and patrol missions in riverine and marshy areas where larger boats could not go.
