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.

Communist forces and weapons

Captured PAVN weapons

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 assault 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]

US weapons

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. 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.

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. 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.^[13]^[14] 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).^[15]

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.^[16]

Captured South Vietnamese warplanes in Ho Chi Minh City

The Vietnam War was the first conflict that saw wide scale tactical deployment of helicopters.^[17] The Bell UH-1 Iroquois nicknamed "Huey" was used extensively in counter-guerilla operations both as a troop carrier and a gunship.^[14] 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.^[14] The Hueys were also successfully used in MEDEVAC and search and rescue roles.^[14] 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 40mm 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.^[18] 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, and is command-detonated and directional shooting 700 steel pellets in the kill zone.

Radios

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:

AN/PRT-4 and PRR-9 squad radios – replaced the AN/PRC-6.^[264]
AN/PRC-6 and AN/PRC-10 – older short range radios, used for outposts^[265]^[266]
AN/PRC-25 and 77 – short-range FM radios that replaced the AN/PRC-8-10.^[267]^[268]

AN/GRC-106 – AM radios and teletypewriter that replaced the AN/GRC-19.^[270]
TA-312 and TA-1 field telephones.^[269]

Encryption systems

Encryption systems developed by the National Security Agency and used in Vietnam included:^[271]

NESTOR – tactical secure voice system, including the TSEC/KY-8, 28 and 38 was used with the PRC-77 and VRC-12
KW-26 – protected higher level teletype traffic
KW-37 – protected the U.S. Navy fleet broadcast
KL-7 – provided offline security
A number of paper encryption and authentication products, including one time pads and the KAL-55B Tactical Authentication System^[272]

Weapons of the PAVN/VC, China, Soviet and North Korea Forces

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.
