F.N.Glossary (Rev. 1.0)
[Ed Note: although originally begun for the purpose of describing Viet Nam slang, it quickly became apparent that a wider audience could be reached by including all military terms used throughout the entire work. Please send comments and corrections to email@example.com]

82: 82mm mortar used by the Viet Cong.
Agent Orange: Agent Orange is the code name for a powerful herbicide and defoliant used by the U.S. military in its Herbicidal Warfare program during the Viet Nam War. Agent Orange was used from 1961 to 1971, and was by far the most used of the so-called “rainbow herbicides” used during the program. Containing dioxins, now known to be notorious carcinogen, it attacked both friend and foe alike.
AK-47: Soviet-manufactured Kalashnikov semi-automatic and fully automatic combat assault rifle, 7.62-mm; the basic weapon of the Communist forces. Known as the ‘Type 56’ to the Chinese, it is characterized by an explosive popping sound.

Boat People: Events resulting from the Viet Nam War led many people in Cambodia, Laos, and especially Viet Nam to become refugees in the late 1970s and 1980s, after the fall of Saigon. In Viet Nam, the new communist government sent many people who supported the old government in the South to “re-education camps”, and others to “new economic zones.” These factors, coupled with poverty caused by disastrous economic reforms, caused millions of Vietnamese to flee the country. On the open seas, the boat people had to confront forces of nature, and elude pirates.
Boot (Camp): See Basic.
Buckle for Dust: to fight, as in combat.
C-Rat (C-Ration): literally “Combat Rations”. Canned meals for use in the field. Each ration consisted of a canned entree, a “B2 unit” containing cheese, crackers and candy, a canned dessert, and an accessory pack.

Cam On Ong: “Thank you” (Vietnamese).

Conex: corrugated metal packing crate, approximately six feet in length.
C.P. (Check Point): A landmark used as a reference on road patrols. Usually a bridge that required a manned watch at night. CPs were manned by a squad of ARVN who lived there and assisted by an MP patrol.

Flak Jacket: During the Viet Nam War, many soldiers, Marines and Airmen received vests that would stop shrapnel, but not a bullet. In the Viet Nam climate they were hot and uncomfortable, and felt heavy and bulky. Nonetheless, they were widely adopted and the soldier in his flak vest became a symbol of the war.

Hearts and Minds: Hearts and Minds was a euphemism for a campaign by the United States military during the Viet Nam War, intended to win the popular support of the Vietnamese people. There is little evidence to show that it was anything other than pro-war propaganda, and rang hollow compared to anti-war publicity efforts. The eponymous film (1974) showed the inherent contradictions of the term, and the term “Hearts and Minds” remains symbolic of the fictional nature of militarist propaganda.
Hooch: building made of bamboo and covered with a thatched roof. Built on stilts to protect it from flooding.

M14: First deployed in 1962, the M14 was unwieldy in the thick brush due to its length and weight. The power of the 7.62 mm NATO cartridge allowed it to penetrate cover quite well and reach out to extended range. The M14 remained the primary infantry weapon in Viet Nam until replacement by the M16 in 1966–1968
M60: The M60 Machine Gun was introduced in 1957 by the U.S. Army. It fires the standard NATO 7.62 mm round and is used as a general support crew-served weapon.

Minigun: When the U.S. entered the Viet Nam War during early 1960s, it found it needed to arm its helicopters to provide additional firepower against enemy infantry. The Minigun, essentially an M60 machine gun with six barrels, could fire up to 4,000 rounds per minute and was soon adapted to the various helicopter mounts (including the AH-1 Cobra and UH1 “Huey“).
Montagnards: (a.k.a. Mountain-Yards or just ‘Yards) literally French for ‘mountain dweller’. In Viet Nam they were often persecuted by the Communists. Easily identified because they are short in stature and darker than the lowland Vietnamese. In many ways, they could be compared to the Native American.
MPC: Military Payment Certificates, were used from the end of World War II until the end of the Viet Nam War.
