The emphasis of this educational reference is on words and phrases that appear in published works about war and military service; and amongst this jargon and slang, there is no pretense of objectivity or completeness, which may be readily found in official documents or government resources. This fragmentary opus is a work in progress ....

Caveat Lector: Vulgar, profane, and obscene dysphemisms, which have been used for every part of speech and rhetorical form, have not been Bowdlerized nor expurgated from this glossary, to the undoubted dismay of purists and the evident enrichment of our mother-tongue; so immature or hypersensitive persons should refrain from perusing this indubitably eclectic and contingently egregious compendium. Swearing is usually either juvenile or crass, but military personnel admire talent and respect skill, so the ability to create imaginative expletives and to craft uncommon scurrility is often appreciated.

[nb: ZIP, ZIPPER, or ZIPperhead may be related to the zippered flying helmet worn by Imperial Japanese during WWII, however one dubious derivation alleges an apocryphal acronym of ZIP, as attributed to the Vietnam-era, being "Zero Intelligence Potential", implying that Asians would not talk if questioned (v: TRUE BELIEVER), so there's no point interrogating a corpse; this communication / culture gap exhibits more ignorance than bigotry, since few Americans bother to learn anything about foreign people or their civilizations] Also, a closure device consisting of two parallel tracks of teeth or ridges that can be interlocked or separated by the movement of a slide between them, so as to fasten parts of clothing, baggage, or the like; this formerly trademarked Americanism is also known as a "slide fastener".

slang for flamethrower, such as the TRACK-driven M-132 mechanized flamethrower; by metonymic extension of the cigarette LIGHTER.

China distilled petroleum into gasoline and kerosene for use as "fierce fire oil" around AD 904; and the flamethrower became a standard copper and glass weapon by 1044. The Chinese invented the unitary match in AD 577; and the SLOW MATCH as a FUSE in AD 919. See NAPALM, MAIN-GUN. Also refers to the popular cigarette LIGHTER (1932) of that brand name [nb: adapted from 'zipper' for its "modern" sound] that was used for ZIPPO MISSIONs.] [v: pyromachy] [nb: the distinctive click made by the retaining latch when opening or closing a Zippo was used as an operational PASSWORD, similar to the toy cricket clicker that was issued to PARATROOPERs for recognition on D-DAY, 6 June 1944]

informal term for a listless person whose behavior or responses are seemingly rote, as an automaton; being anyone who is mentally or emotionally disengaged or distracted. While immersed in the throes of battle, some men experience an indifference to fear, and are careless of injury or death; which condition is formally known as "combat narcosis". The stupor and torpor of narcotism can be misinterpreted as heroism or patriotism, but it is more akin to fatalism, and does not generate ESPRIT DE CORPS among GOOD STICK/GOOD PEOPLE. Term was introduced into American society around 1810, but usage became prominent during the CIVIL WAR; although referring to the supernaturally reanimated dead who exhibit a semblance of mechanical life, this term originally meant 'god'. See COSR, PTSD, BUBBLE, THOUSAND-YARD STARE, TELESCOPING, BLACKOUT, FLASHBACK, FIGHT-OR-FLIGHT, DISSOCIATION, OBJECTIFICATION, STRESS OF SOUL, BROKEN-WING SYNDROME. Also, slang during WWII-era for a Canadian conscript assigned to home defense duty; as a soldier so bored to death that only enforced regulations can animate his corpse ... a living person enslaved to listlessly perform routine tasks after his soul has been magically removed by the government.

Also, an informal GULF WAR-era euphemism for those people who are worthless, have no useful intelligence, and live-off the rest of their fellow creatures; by extension of its common reference for the "undead"; the mind-sets of such people will not let a favored factoid or cherished myth be killed, so they must bring it back to life, hence the landscape is populated by animated corpses that are broken and bent but unbowed. [nb: "Feeling worthless is the way the jerks want you to feel. If everybody felt like a zombie, we'd all be on the same level, and the jerks could get away with the things jerks want to get away with. They're not dull; but jerkiness isn't as respectable as it used to be ... not even in tinseltown, which is why they had to build an even more outlandish glittertown. You have to watch out which playmates you pick, or they'll turn you into a zombie." paraphrase of John Ross Macdonald (Kenneth Millar)]

referent for the individual isolation that enables total concentration and complete indifference to externals, as a warrior's focus; sometimes called a BUBBLE; see COLD ZERO, HEAD IN THE GAME, SPIDER SENSE, COLD-BLOOD, DISSOCIATION, OBJECTIFICATION, TELESCOPING, STRESSOR, STRESS OF SOUL.

a truncation of 'zoom' or ZOOMIE, being a slang reference to the United States Air Force Academy (USAFA) established in 1954 at Colorado Springs, CO; also called ALUMINUM U; see THE BIRD, DOOLIE, JUNIOR BIRDMAN, CADET, RING-KNOCKER, TRADE SCHOOL, OCS, ROTC. [v: Military Schools] [v: Siwash ("At Good Old Siwash" by George Helgeson Fitch (1911)] Also, nickname for Nga Tu So (the So Intersection) and Pha Phim (Film Studio) (geo: 21 00 00N 105 49 30E; UTM: 48QWJ85732217), site of major NVN prison camp for captive allied population; also known as [nb: some names only refer to sections within this prison] Zoo Annex, Cu Loc, BOQ, Camp Two, Camp America.

This was the location of the PAVN motion picture institute's film studio before the Second INDOCHINA War. It is located in a residential area in the southwest suburbs of Hanoi, on the east side of Nguyen Trai Street (the road to Ha Dong City), a short distance north of Cau Moi (the "New Bridge"). In 1965, the facility was transferred temporarily to the Enemy Proselyting Department for use as a POW camp. In about April 1972, Office 22 of the newly formed PAVN Group 875 took responsibility for administration of this and other US POW camps in North Vietnam. After the war this facility was returned to the PAVN motion picture institute. See POW.
