THC Science

This article is about the weapons used in the Vietnam War, which 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 Army of the Republic of Vietnam (ARVN), United States, Republic of Korea, Philippines, Thailand, and the Australian, New Zealand defence forces, and a variety of irregular troops.

Nearly all United States-allied forces were armed with U.S. weapons including the M1 Garand, M-14 and M-16. The Australian Army employed the 7.62 mm L1A1 Self-Loading Rifle as their service rifle, with the occasional US M16.

The NVA, 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. In addition, some weapons—notably anti-personnel explosives, the K-50M (a PPSh-41 copy), and “home-made” versions of the RPG-2—were manufactured in 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, 9 types of antitank weapons, and 14 anti-aircraft artillery weapons used by ground troops on all sides. Also in use, primarily by anti-communist forces, were the 24 types of armored vehicles and self-propelled artillery, and 26 types of field artillery & rocket launchers.

Communist forces and weapons

Communist forces were principally armed with Chinese and Soviet weaponry though some Viet Cong 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.

US weapons

The American M16 rifle, which replaced the M14, was lighter and considered more accurate than the AK-47 but was prone to jamming. Often the gun suffered from a jamming flaw known as "failure to extract," which meant that a spent cartridge case remained lodged in the chamber after a bullet flew out the muzzle. According to a congressional report, the jamming was caused primarily by a change in gunpowder which was done without adequate testing and reflected a decision for which the safety of soldiers was a secondary consideration.

The heavily armored, 90 mm M48A3 Patton tank saw extensive action during the Vietnam War and over 600 were deployed with US Forces. They played an important role in infantry support though there were 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.^[1]^[2] 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 NVA. It was countered by the long-range, American 175 mm M107 Self-Propelled Gun.^[3]

The United States had air superiority though many aircraft were lost to surface-to-air missiles and anti-aircraft artillery. U.S. air power was credited with breaking the siege of Khe Sanh and blunting the 1972 Communist 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 for the city of Hue, providing accurate fire in support of the U.S. counter-offensive to retake the city.^[4]

The Vietnam War was the first conflict that saw wide scale tactical deployment of helicopters.^[5] The Bell UH-1 Iroquois was used extensively in counter-guerilla operations both as a troop carrier and a gunship.^[2] In the latter role, the "Huey" as it became affectionately known, was outfitted with a variety of armaments including M60 machine guns, multi-barreled 7.62 mm Gatling guns and unguided air-to-surface rockets.^[2] The Hueys were also successfully used in MEDEVAC and search and rescue roles.^[2]

Communications

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:^[12]

The AN/PRT-4 and PRR-9 squad radios replaced the AN/PRC-6.
The AN/PRC-25 and 77 short-range FM radios replaced the AN/PRC-8-10.
The AN/VRC-12 series FM radios replaced the RT-66-67-68/GRC (including AN/GRC 3-8, VRC 7-10, VRC 20-22, and VRQ 1-3 sets).
The AN/GRC-106 AM radios and teletypewriter replaced the AN/GRC-19.

Encryption systems

Encryption systems developed by the National Security Agency and used in Vietnam included:^[13]

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

Weapons of the PAVN/NLF/North Korea/Soviet Union/China

NVA (North Vietnamese Army) and the Southern communist guerrillas NLF, or Viet Cong as they were commonly referred to during the war, largely used standard Warsaw Pact weapons. Weapons used by the North Vietnamese 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 '50, US material captured in Korea was also sent to the Vietminh.
