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.

OA :
Objective Area, being the tactical goal or strategic aim of air, ground, or amphibious missions; compare AO, TO, AOR, MOA, TAOR, CHOP LINE, UA.

OAN HON :
in Vietnamese eschatology, a spirit in purgatory, usually condemned to haunt the region of its death, until released by the beneficence or sacrifice of others. See TIGER BALM; compare PHI, HUNGRY GHOST. [nb: since the November 1965 battles (SILVER BAYONET) in the Ia Drang valley, the area has been referred to as the "Forest of Screaming Souls"]

"The talk of him that sweareth much maketh the hair stand upright." Ecclesiasticus 27:14 Apocrypha; "In certain trying circumstances, urgent circumstances, desperate circumstances, profanity furnishes a relief denied even to prayer." by Mark Twain (Samuel Langhorne Clemens); "Take not God's name in vain; select a time when it will have effect." by Ambrose Gwinnett Bierce; "Grant me some wild expressions, Heavens, or I shall burst." by George Farquhar; "When angry, count four; when very angry, swear." by Mark Twain (Samuel Langhorne Clemens); "A whoreson jackanapes must take me up for swearing; as if I borrowed mine oaths of him and might not spend them at my pleasure. ... When a gentleman is disposed to swear, it is not for any standers-by to curtail his oaths, ha?" by William Shakespeare; "A footman may swear; but he cannot swear like a lord. He can swear as often: but can he swear with equal delicacy, propriety, and judgment?" by Jonathan Swift; "'Twas but my tongue, 'twas not my soul that swore." by Euripides; "It comes to pass oft that a terrible oath, with a swaggering accent sharply twanged off, gives manhood more approbation than ever proof itself would have earned him." by William Shakespeare; "And when the riflemen heard their commander swear so prodigiously, their minds were filled with amazement to learn how little they knew of profanity!" said of Daniel Morgan during the AMERICAN REVOLUTION] [v: protomartyr Saint Stephen was canonized for blasphemy]

OATH OF ALLEGIANCE :
see PLEDGE OF ALLEGIANCE, LOYALTY OATH, PROMISE, CREED, OATH, CODE OF CONDUCT, DUTY, HONOR CODE, LOYALTY UP - LOYALTY DOWN, BRASS-COLLAR, A MAN'S GOTTA DO WHAT A MAN'S GOTTA DO, CUSTOMS AND COURTESIES OF THE SERVICE. [v: Disqualification Act, Alien and Sedition Act, Reconstruction Act]

Also, the abbreviation for Operations Base; see FOB.

OBA :
Oxygen Breathing Apparatus; being a rebreathing device, with mask and goggles, providing a source of clean air for working (eg: firefighting, evacuation) in a smoke-filled environment; compare EEBD, SCUBA, GAS MASK.

OBC :
Officer's Basic Course, being the introductory branch-specific training for newly commissioned officers, especially those from ROTC programs; formerly known as Basic Officer's Course (BOC); see TBS. [nb: Germany has traditionally trained its officer candidates in an eight week basic course at one of several academies (kriegsschule) before sending the graduates along to further training for varying periods in their branch specialization]

OBE :
Order of Battle Echelon; see OB, compare TO&E/TOE, MTOE. [cf: battalia]

OBEY :
to comply with or follow the instructions, directions, restrictions, commands, or any other lawful ORDERs issued by the CHAIN-OF-COMMAND, without hesitation or mental reservation; to submit or conform in action to authoritative guidance.

OBJECTIFICATION :
the practice of degrading things, events, and processes to the status of insensate or inanimate objects, as by the use of impersonal or mechanistic labels, such as TARGET, ZONE OF FIRE, BUSTING CAPS, ROCK 'n' ROLL, HOSE, MAD MINUTE, COLLATERAL DAMAGE, TWEP. This is a coping mechanism that dehumanizes someone's conduct or behavior; it's a form of spiritual or emotional desensitization by causal distancing or connective disengagement. Without OBJECTIFICATION, combatants have a tendency to become dysfunctional from supersensitivity or hyperphysicality, neurotic from evasion or abstraction, or psychotic from immersion or supersaturation. See STRESS OF SOUL, THOUSAND-YARD STARE, ZOMBIE, BLACKOUT, FLASHBACK, WATERWORKS, CONVERSION SYMPTOMS, PTSD, TELESCOPING, DISSOCIATION, BROKEN-WING SYNDROME, FIGHT-OR-FLIGHT, COMBAT BUM, TOUR BABY, TWO-FISTED, HOMESTEADER.

This training course is also known as an "assault course" or "commando course", and includes wall climbing, low-crawling under wire, balance running, agility running, ditch jumping, rope swing, net climbing, and the like. Sometimes mistakenly called a CONFIDENCE COURSE (qv); the completion of an OBSTACLE COURSE is an individual effort, while satisfying the requirements of a CONFIDENCE COURSE is a team or group effort. [v: steeplechase]

OC :
abbreviation for Officer Candidate; see OCS, CADET; compare WOC. Also, abbreviation for Observer Controller, being the designation for umpire or referee CADRE who monitor FTX and war game EXERCISEs for procedural compliance, safety and security; see KNOCK IT OFF, OPFOR, MOCK-COMBAT, WAR GAMES, STOOGE, OFF THE RESERVATION, OUTSIDE THE WIRE, WE DON'T NEED NO STINKIN' BADGES, ALL'S FAIR IN LOVE AND WAR, RULES OF ENGAGEMENT (ROE).

See BERLIN WALL; compare CONDOMINIUM.

OCCUPY :
to take possession and control of a place, to militarily seize and hold a position, to capture and secure a territory.

O CLUB :
short for Officer's Club, the "Officer's Open Mess" on posts and bases around the world, where OFF-DUTY dress and deportment is regulated as much as in any DUTY assignment or BILLET, and perhaps scrutinized even more by wives who manage their husband's careers! Each O CLUB is variously provided with dining rooms, ballroom, barrooms, snack bar, game room, CLASS SIX store, barbershop, picnic area, swimming pool, golf course, trap or skeet range, boating area, and the like; usually located near HQ buildings, main chapel, and VOQ. Although the NCO Club is similar, the EM Club [v: SLOP CHUTE] or Service Club is primitive by comparison. See RIGHT ARM, DINING-IN, MESS, GALLEY, CANTEEN, ANNEX, PARTY SUIT, DIRTY SHIRT, BEARING, DISTAFF. [cf: barrelhouse, cocktail lounge, saloon, roadhouse, speakeasy, blind pig / blind tiger, pub, ginmill, public house, tavern, cantina, bar, barroom, bar-and-grill, grogshop, watering hole, tippling house, 11th Frame, 19th Hole, honky-tonk, dive, brasserie, bistro, taproom, beer joint, beer parlor, brewpub, alehouse, rathskeller, cabaret, nightclub, drinkery] [v: "What happens in the club stays in the club!"]

OCS :
Officer Candidate School
insignia
OCS roadwheel
(oh-see-ess; not "ox") Officer's Candidate School; sometimes called "Organized Chicken Shit", and the former enlisted graduates are widely known as "Ninety Day Wonders" or "Ninety Day Blunders" from the length of the original WWII training period, commencing in 1941. Primarily oriented toward training combat arms (ie: Infantry, Armor, Artillery) officers for company-level assignments during wartime, the OCS program has also been intermittently offered in Signal, Ordnance, Transportation, Engineer, Chemical, and Medical Service Corps branches since its inception. A separate WAC OCS program was episodically offered until women were fully integrated into the Armed Forces in 1976. Beginning during WWII, OCS was the first training course to be racially desegregated. The OCS program is also available to reservists, and is known as Officer Training School (OTS) by the USAF. In 1918, ROTC was suspended in favor of the Student Army Training Corps to train enlisted men (EM) for special wartime assignments. To correct the deficiencies of the original WWII program, OCS was extended to 22-weeks during the KOREAN WAR, and to 26-weeks during the VIETNAM WAR; but in April 1973, the program was reorganized into a 14-week branch immaterial course at Fort Benning. A student training in OCS is properly known as a "candidate" [or more formally an "officer candidate" (OC)], which is unlike the terms for CADET used in the various TRADE SCHOOLs. In the post-Vietnam era, the OCS emblem, once worn as a PATCH and later as a helmet BADGE, has acquired the nickname "roadwheel". [nb: Vietnamese term: Truong Sinh Vien Si Quan] [v: Siwash ("At Good Old Siwash" by George Helgeson Fitch (1911)] [nb: Germany has traditionally trained its officer candidates in an eight week basic course at one of several academies (kriegsschule) before sending the graduates along to further training for varying periods in their branch specialization] [v: "What happens in school stays in school!"]

OCTOPUS :
slang for the Department of Homeland Security (DHS), because it lives in the darkest depths, has tenticles that intrude everywhere, and defends itself with a blinding effusion of ink. Also, something likened to an octopus, as a masterful executive with many forms of far-reaching influence or control.

OD :
Olive Drab color, as standard dull "Olive Green" (OG) military color. The wear of olive drab (OD) is no longer authorized after 30 April 2008. [nb: the human eye can discern more shades of green than any other hue] [nb: except for rifle regiments separate from infantry and dragoons from before the War of 1812, the U.S. Army wore blue uniforms until the adoption of KHAKIS and FATIGUES, so when the CLASS-A uniform was redesigned in 1954, the color Army Green (AG44) was selected for its historical link to the early riflemen and SHARPSHOOTERs; then in 2008, the traditional Continental Army blue color was restored] Also, Operational Detachment; see ODA, ODB, ODC. Also, improper abbreviation for Officer of the Day / Deck (OOD); see DUTY DOG, DOG ROBBER, DOGSBODY, CDO, SDO, SOPA.

ODA :
(oh-dah) Operational Detachment Alpha, being an A TEAM in the US Army SPECIAL FORCES. The USSOCOM protocol for ODA numbering (effective 2007) is: the first digit represents the SF Group (eg: 1SFGA=1, 3SFGA=3, 10SFGA=0, 19SFGA=9, 20SFGA=2); the second digit represents the Battalion (ie: 1-4); the third digit represents the Company (ie: 1-3); and the fourth digit represents the Detachment (ie: 1-6). The older 3-digit notation differed by having the second digit identify both the company and battalion (ie: 1=A Co 1st Bn, 2=B Co 1st Bn, 3=C Co 1st Bn, 4=A Co 2nd Bn, through 9=C Co 3rd Bn). Six A TEAMs or ODAs comprise a company (CO), three SF Companies comprise a battalion (BN), and four SF Battalions comprise a group (effective 2007); each active duty SF Group specializes in the languages and cultures of a particular region (ie: 1st SFGA in East Asia; 3rd SFGA in Africa, Mid-East, and Central Asia; 5th SFGA in Mid-East and Central Asia; 7th SFGA in South America; and 10th SFGA in Europe). In developing a new interservice amalgamation, USSOCOM has redesignated the 'ODA' as a generic "special operations detachment", disconnecting its formerly strict affiliation with SF/USSF.

O-DARK-30 / O-DARK-THIRTY :
(oh-dark-thirty) a vague reference to some unspecified time when most other people are OFF-DUTY or asleep, as "worked till O-DARK-30", or "awoke at O-DARK-30"; also represented as "oh-dark-early", but never expressed as 0-dark-30 or zero-dark-thirty, despite the fact that only numerals are used in military computation. This early (or late) time segment is also known as "the darkest hour", the "wee hours", and before the "crack of dawn". See WHITE NIGHT, TIME.

ODB :
(oh-dee-bee) Operational Detachment Bravo, being a B TEAM in the US Army SPECIAL FORCES. [nb: six A TEAMs or ODAs comprise a company (CO), three SF Companies comprise a battalion (BN), and four SF Battalions comprise a group (effective 2007); each active duty SF Group specializes in the languages and cultures of a particular region (ie: 1st SFGA in East Asia; 3rd SFGA in Africa, Mid-East, and Central Asia; 5th SFGA in Mid-East and Central Asia; 7th SFGA in South America; and 10th SFGA in Europe)]

ODC :
(oh-dee-see) Operational Detachment Charlie, being a C TEAM in the US Army SPECIAL FORCES. [nb: six A TEAMs or ODAs comprise a company (CO), three SF Companies comprise a battalion (BN), and four SF Battalions comprise a group (effective 2007); each active duty SF Group specializes in the languages and cultures of a particular region (ie: 1st SFGA in East Asia; 3rd SFGA in Africa, Mid-East, and Central Asia; 5th SFGA in Mid-East and Central Asia; 7th SFGA in South America; and 10th SFGA in Europe)]

OEF :
Operation Enduring Freedom
patch
OEF
Operation Enduring Freedom, from 7 October 2001, conducted in Afghanistan, South Africa, and the Philippines; compare OIF, see GULF WAR, WAR ON TERROR. [v: Gulf War Supplement]

OER :
Officer Efficiency Report; based on character and efficiency (C&E) rating. See FITREP, ER, DOR, BAYONET SHEET.

OFF-DUTY :
time when military personnel are not assigned to specific tasks, often coincident with personal time, STAND-DOWN, PASS, or LEAVE; a military myth, because servicemen do not have protected working conditions! Nobody in the military is guaranteed anything, except due-process when they disobey. Anyone may be recalled from OFF-DUTY whenever there skills are needed. See DUTY; compare FEDERAL FRIDAY. [v: dog days] [nb: "The sabbath was made for man, and not man for the sabbath." Mark 2:27 KJV Bible]

OFFHAND / OFF-HAND :
the unsupported standing position for firing RIFLE or PISTOL; shooting a pistol one-handed or a rifle without a prop or rest (including the sling wrapped as a brace) as executed from a standing or kneeling posture; also known as "freestyle" or "free-hand"; see KICK, SPOT WELD, SIGHT PICTURE, BASS. Also, any abrupt or impromptu act, any casual or cavalier behavior.

OFFICE HOURS :
in the Marine Corps, a unit hearing for minor offences before the commander at which non-judicial punishment may be imposed; see ARTICLE 15, ADY, DRUMHEAD, YELLOW SHEET, ROCKS 'n' SHOALS, UCMJ, compare CAPTAIN'S MAST.

OFFICER :
(off-ick-cur or ossif-fer) any MIL-PERS anointed by an ACT OF CONGRESS with some form of commission (eg: warrant, direct, regular, reserve, etc) which, the recipient infers, purportedly bestows ineluctable suavity and character, or unimpeachable wisdom and honor, such that he deserves the distinguished title of "sir" (cur) rendered with a SALUTE for the monumental restraint of non-FRATERNIZATION! ... in other words, anyone who sleeps and eats and acts like everyone else and who is mysteriously converted by appointment into believing that his shit no longer stinks! As one distinguished veteran said: "The only reason you are given any special consideration is because you will use your superior ability to take care of your men and lead them into battle." See AIDE, MISTER, WO, WOBBLY, MAVERICK, OCS, CADET, PIP, TRADE SCHOOL, ROTC, BOAT SCHOOL, HUDSON HIGH, RING-KNOCKER, MUSTANG, BLUE BLOOD, OIC, OOD, SDO, CO, OLD MAN, SKIPPER, HONCHO, WALLAH, MOTHER HEN, LDR, RHIP, ROUGHSHOD, GREEN TAB, LINE OFFICER, ENSIGN, LT, LOOEY, SHAVETAIL, BUTTER BAR, BROWN BAR, CAPTAIN, AIMING STAKES, MAJOR, COMMANDER, LIGHT BIRD, FULL BULL, FLAG OFFICER, WHITE WAY, COMMAND ELEMENT, CHAIN-OF-COMMAND, MILICRAT, RANK. [nb: Vietnamese term: Si Quan] [nb: although the USAF phased-out their Warrant Officer ranks in 1979, designating technical personnel as NCOs and command personnel as officers, they did not resume the WWII Army Air Corps program of "Flying Sergeants", inasmuch as pilots and weapons officers are "technicians" ... so a Lieutenant "commands" a one- or two-person aircraft worth $20-million but a Sergeant "commands" a three- or four-person tank crew worth $60-million!] [nb: the word "caddie", with the same origin as CADET, and sometimes shortened to "cad" (irresponsible, dishonorable), was the 17th century term for a gentleman who learned the military profession by serving in the army without a commission; henceforth, it was applied to any person seeking employment] [nb: until recently, an OFFICER was simultaneously designated a "gentleman" when appointed by an ACT OF CONGRESS, which not only inspired further intellectual development but also encouraged cultural sophistication, which refinements were mocked as being 'suave and debonair' (deliberately mispronounced as "soo-wave" and "dee-boner"); v: BRASS HAT, BLUE BLOOD, UP THE HAWSEPIPE, OFFICER'S COUNTRY, TALLY-HO, TACT; cf: HARD-ASS, MACHO] [nb: "Oh he's doing fine, Michael. Nevertheless, he's an officer and a gentleman, and that's no job for a gentleman." by Frank S. Nugent and John Ford in Fort Apache (1948, based on the story "Massacre" by James Warner Bellah); "The worst thing about this war is the chance it gives these dreadful little persons (commoners), the chance to make themselves important." by Arthur Wimperis, George Froeschel, James Hilton, and Claudine West in Mrs. Miniver (1942); "There is no place for a caesar in the army ... I have stood by and watched poor officers rise above me, and I've seen great officers march out their lives in one rank when they should've worn stars. I've seen bribery and favoritism and cheating. I've saluted men I knew to be scoundrels. I've seen officers rot away in some little sagebrush post while others bore gold braid in Washington city without reason. It is unfair. It is hard. It is brutal. But you've got to learn it, and do your duty as you set it, and make that your one consolation. I can't talk to him, and you can't. He's got to sit there and go through every damned bit of it alone. He'll be a great man if he does; he won't be anything you'd want if he doesn't. I don't know whether God hates a political general or a grandstand swashbuckler, but I do. And I cannot take the chance of sending him out with twenty men he'll lead to slaughter for the sake of ambition." by Ernest Haycox The Border Trumpet (1936)]

OFFICER'S CALL :
an early morning meeting of all subordinate officers with their immediate superior, sometimes convened as a breakfast gathering at the commander's discretion, for the purpose of discussing unit problems, checking on work in progress, and assigning new details or duties. This meeting is known as "Captain's Call" on-board ships; and is commonly derided as "morning prayers". See BRIEFING, CONFAB, EAR-BANG, CROSS-TALK, CHATTER, HALF-MAST, CHIN CHIN, POWWOW, SUMMIT. [cf: consistory, gabfest]

OFFICER'S COUNTRY :
refers to where officers live and work, such as HQ, MESS, BOQ, VOQ, NOB HILL, WARDROOM, and other QTRS, but is especially noted on-board ships, where separation is both functional and social. Compare BELOW DECK; see TOPSIDE, ABOVE BOARD, MUSTANG. [nb: until recently, an OFFICER was simultaneously designated a "gentleman" when appointed by an ACT OF CONGRESS, which not only inspired further intellectual development but also encouraged cultural sophistication, which refinements were mocked as being 'suave and debonair' (deliberately mispronounced as "soo-wave" and "dee-boner"); v: BRASS HAT, BLUE BLOOD, UP THE HAWSEPIPE, TALLY-HO, TACT; cf: HARD-ASS, MACHO]

OFFICER'S MESS CHEST :
also called a field mess chest; see CANTEEN; compare MESS KIT. [cf: chuck box, grub box]

OFFICER'S WIFE :
a woman who uses her native wit and feminine wile to acquire, by fair means or foul, a military spouse who is sufficiently malleable to be converted into her ideal (ie: the transsexual version of herself) but without the onus of devoting an excess of time or effort in attaining this expectation, and who is almost as monomaniacally ambitious as herself, but can be driven to greater achievements by the promise of several illicit inducements, covert or clandestine, until either high enough rank is obtained or compulsory retirement intervenes, at which point she too retires, never to be nice to anyone again! Formerly a lady and once a frontierswoman, serving in partnership with her mate and sharing in his adversities, but lately a highly polished female, more ornamental than practical, less enduring than brittle, possessing a stainless steel smile and envious eyes in every shade of jealousy. Her rigid spine forgives nothing, her soft bosom comforts only herself, and her moral scale is so finely balanced that everyone is found wanting, and none is better than her. She wears her husband's rank, immodestly goes where she doesn't belong, and no soldier is rude enough to tell her to go away ... not even her sponsor. Although she marries into the military lifestyle, she resents its obligations and resists its impositions, making her sponsor and BRATs pay in myriad and sundry ways for each and every unhappy limitation upon her fickle nature, being at best an asset, and at worst a deterrent to the career of a MIL-PERS. The only difference between her and her sisters strolling the street outside the gate is the price that is charged for services rendered. The gracious and dedicated exception, so fine when rarely encountered, proves the rule. See COW, PETTICOAT COMMAND, DRAG, CAMP FOLLOWER, RING THE BELL, THE DAUGHTER OF THE REGIMENT, THE MOTHER-IN-LAW OF THE ARMY, CLASS-B DEPENDENT, CAMPAIGN WIFE, DISTAFF, BITCH, SKIRT, BRAT, GREEN BLOOD, ARMY SOUP. [v: officer's wife syndrome, professional widow] [nb: "They also serve who only stand and wait" by John Milton; "It is women who knit the lamb's wool cloak in which barbarism masquerades as civilization."] [nb: "If the military wanted you to have a wife, they'd have issued you one." serviceman's adage] [nb: until the Vietnam-era, the military did not recognize the spouse or other dependents of enlisted personnel below the non-commissioned officer ranks]

OFF LIMITS :
areas prohibited or denied to unauthorized access, also known as "restricted access" or "out of bounds", such as firing ranges, munitions training areas, weapons storage areas, operational security areas, intelligence briefing areas, prisoner detention areas, communications equipment areas, medical treatment facilities, and the like. Some paternalistic restraints have been selectively prescribed for "the good of the service", such as excluding servicemembers from posted civilian establishments (ie: clip joint, roadhouse, tourist trap, etc), and confining travel by mileage limits calibrated to PASS/Liberty periodicity (eg: 150mi for 36hr, 250mi for 72hr, 300mi for 96hr).

OFF THE RESERVATION :
used literally to specify persons or regions outside the military COMPOUND, post, or BASE, and used figuratively to represent any unauthorized conduct or unsanctioned action; phrase most often refers to a person or situation which is "unresponsive" to command authority or is "out of control" by improvisation, being more extra-legal than illegal; sometimes known as "off the map" or "off the grid", "off the radar" or "off the books", as being without guidance, unaccountable or undetectable. Also, used as a synonym for overseas (OCONUS), being anywhere outside the Zone of the Interior (ZI) or the continental United States (CONUS), with the clear implication that different rules apply in a "foreign realm" or "alien territory" appertaining to everything from sexual mores and substance abuse to professional accountability and LAWS OF WAR.

On, on, you noblest English. / Whose blood is fet from fathers of war-proof! / Fathers that, like so many Alexanders, / Have in these parts from morn till even fought / And sheathed their swords for lack of argument: / Dishonour not your mothers; now attest / That those whom you call'd fathers did beget you. / Be copy now to men of grosser blood, / And teach them how to war. And you, good yeoman, / Whose limbs were made in England, show us here / The mettle of your pasture; let us swear / That you are worth your breeding; which I doubt not; / For there is none of you so mean and base, / That hath not noble lustre in your eyes. / I see you stand like greyhounds in the slips, / Straining upon the start. The game's afoot: / Follow your spirit, and upon this charge / Cry 'God for Harry, England, and Saint George!' [nb: not "once more into the breech"]

[v: Knife Terms; The Language of Swordplay] [nb: the "spirit of the bayonet" is "to kill!" ... not only was the word "kill" banned from the training and indoctrination (TRADOC) vocabulary (see SMACK) during the VIETNAM WAR, but bayonet, pugil stick, and hand-to-hand close combat training have since been eliminated from soldierly preparation. Although the "little corporal" Napoleon claimed that three hostile newspapers are to be feared more than thousands of BAYONETs, Voltaire said, as both social and political philosophy, that "You can do anything with a BAYONET, except sit on it!".

rhyming slang satirizing continuous field operations in contrast with piecemeal relief and replacement; being a method that contradicts the COMBAT EFFECTIVEness of whole unit rotation, necessary refit, and integrated replacement training ... a catch-phrase that probably inspired the later civilian expression: "shop 'til you drop". See OPTEMPO, WETSU.

OPTION IV :
US plan to evacuate Saigon.

OR :
Operating Room in a hospital. Also, ORDERLY ROOM. Also, Operational Readiness.

ORANGE FORCE :

ORDEAL :
a test or putting to the proof, as someone subjected to distress, suffering, or grievous experience; also known as a "trial by ordeal", a "trial by fire", or a "trial by combat". In the time before the reign of the anti-hero in this modern era of "God is dead", people believed that ultimate truth would be revealed, that it could not be hidden or obscured, distorted or obliterated, hence the quest for spiritual fulfillment and the moral basis for proper conduct. People sought to propitiate what they could not control, and subjected each other to tests as verification of worthiness; the mediums of fire and water employed in these ordeals does not condemn, but enables the sinner to condemn himself. Before its degeneration into a contest to settle a private quarrel, the DUEL was a consecrated ORDEAL representing the spiritual embodiment of metaethical forces engaged in "trial by combat", wherein divine judgment would decide the "single combat" issue, and "God's Will" would be represented by victory. See ACT OF TRUTH, CARTEL, DUEL, GANTLET, OATH, CROSS SWORDS, MEASURE SWORDS, SNAKE PIT, FIELD OF HONOR, KEEP YOUR SHIRT ON, HOLD ONE'S FEET TO THE FIRE, GAUNTLET, CUTTHROAT, BLOOD ALLEY, MARATHON, PAIN.

ORIENTEERING :
a paramilitary training and civil affairs activity practiced by MIL-PERS, including CADETs and CRUITs, that promotes teamwork, leadership, physical fitness, and navigational skills, which are useful to military components ... ORIENTEERING is a recreational pastime, not unlike sport parachuting, that appeals to military servicemembers. As with fencing and polo, this sport originated as a military exercise, and was first open to competition in 1897 near Oslo Norway, then the first large scale meet was organized in 1918 near Stockholm Sweden. The sport developed (being the impetus for the 1933 invention of the Swedish protractor COMPASS) and expanded worldwide; and although Silva co-sponsored an event at Dartmouth College in 1941, ORIENTEERING was not established in America until the Vietnam-era. The International Orienteering Federation (IOF), which sets rules and regulates competition, was founded in 1961; and the United States Orienteering Federation (USOF) was founded by members from the Quantico Club in 1971. ORIENTEERING is an activity in which cross-country trekkers use a detailed map and a compass to locate control sites (WAY POINTs) in the landscape. A standard ORIENTEERING course consists of a start (triangle), a series of demarcated control sites (circles), and a finish (double circle). The control sites, numbered in the order that they are to be visited, are marked by circles connected by lines on a map, and by distinctive panels ("markers") on the ground. The control sites are positioned at features that are to be found, and include a control description (or "clue") that clearly identifies the site. The route between control sites is not specified, so the selection of the best navigational pathways is the essence of this sport. ORIENTEERING exists in two basic forms: accuracy and timed events; it is also undertaken by individuals or teams that compete from staggered, relay, or mass starts. Although the timed events have an element of accuracy, with competitors checking through a series of remote stations, they are primarily speed races, from sprints to overnighters, conducted on foot ("foot-o"), mountain bicycle ("bike-o" / "MTBO"), X-C ski ("ski-o"), or boat ("canoe-o"). Other timed events include hash marking ("hash-o" / "blaze-o"), hill climbing ("billy goat"), extreme terrain ("extreme-o"), Rugged Outdoor Group Activity Involving Navigation and Endurance ("ROGAINE"), timed-out scoring ("score-o"), and Amateur Radio Direction Finding ("ARDF" / "radio-o"). The accuracy events ("trail-o") are untimed and are typically much more difficult to navigate. In trail-o competitions, it is not uncommon for the course to have false goals at pivotal control sites to increase the challenge. Trail-o courses are also open to handicapped persons, such as disabled veterans, where canes, crutches, and wheelchairs are not inhibiting factors. ORIENTEERING, which can also be conducted in urban areas and underwater seascapes (v: SCUBA ORIENTEERING or "scuba-o"), uses a variety of maps (eg: 1:15,000 magnetic, road map, MOSAIC, TOPO, etc), prefers a wrist or thumb COMPASS, but does not use the military GRID COORDINATES system ... use of a GPS or other electronic locator is prohibited. Other than suitably rugged outdoor attire, there is no ORIENTEERING uniform, and team equipment costs are low. For those unable to participate in an organization's shooting team or drill team, ORIENTEERING can be an alternate sponsored activity. [nb: "ROGAINE" actually derives from the names of its originators in Australia: Rod Gail and Neil Phillips; cf: STABO] [cf: hide and hunt, scavenger hunt, LETTER BOX hunt, treasure hunt]

ORIENTAL FAN :
slang reference to an enthusiastic Western convert to the exoticism of Asian customs and peoples; the partisan expressions of such a proselytizing aficionado is commonly known as YELLOW FEVER; see GONE NATIVE, EXILE, BAMBOO ENGLISH, SLEEPING DICTIONARY, POINTIE TALKIE, BRACELET, JOSS STICK, SPIRIT MONEY, BAMBOO, RICE BALL, BUSH HANKY; compare RICE CHRISTIAN, YELLOW PERIL.

Lockheed P-3 propeller-driven aircraft, used for electronic and anti-submarine warfare; see ASW, MAD, DASH, compare LIGHTNING.

ORV :
Off-Road Vehicle, being an enclosed four-wheel drive (4WD) automobile used to transport passengers; also known as an "off-highway vehicle" (OHV) or "sport utility vehicle" (SUV), as opposed to a sedan, JEEP / HMMWV, or TRUCK. Fleet purchase of the International "Scout" in the 1950s began the procurement trend away from vehicles built to MIL-SPEC (like the JEEP and HUMVEE) that were later "civilianized" for sale to the general public, and toward the purchase of commercial models that only needed to be painted in military livery.

OSCAR :
the word assigned to represent the letter "O" in the international phonetic alphabet; at various times in different spelling schemes, it has also been acrophonetically represented as Oboe and Opal; it is sometimes spelled "oskar".

The amphibious MV-22 OSPREY is scheduled to replace the CH-46 SEA KNIGHT.

OSS :
Office of Strategic Services
patch
OSS
(oh-ess-ess) Office of Strategic Services; sometimes called "Donovan's Dilettantes", but widely misrepresented as "Oh So Social" or "Oh So Silly". Evolving from the Coordinator of Intelligence (COI) in July 1941 and the JCS Office of War Information (OWI) in June 1942, the OSS was developed from 13 June 1942 to engage in "unorthodox warfare" (eg: subversion, espionage, counter-espionage, intel, psy-war, guerrilla warfare, sabotage, economic warfare in support of military operations); and was patterned on the British Special Operations Executive (SOE, formed 19 July 1940, which was known as the "Ministry of Ungentlemanly Warfare"). OSS subdivisions specialized in processing information and direct action;including sections: Research & Analysis (RA), Secret Intelligence (SI), Special Operations (SO), Operational Groups (OG), Maritime Unit (MU), CounterIntelligence Branch (X2), Morale Operations (MO), School & Training Branch. OSS teams operated in Southeast Asia at the end of WWII, and recommended Vietnamese autonomy under Ho Chi Minh. OSS was disbanded Sept 1945, and was a forerunner of both the CIA and Special Forces (USSF). See SACO, JACK, SECRET AGENT, CRYPTO, TRADECRAFT, PROVOCATEUR, SPOOK, SHANGRI-LA, COUNTRY CLUB, FINISHING SCHOOL.

Morgan (1957)] [nb: for an authentic anecdotal account of a WREN selected and trained for offensive CT ops in Northern Ireland, see One Up: A Woman in the SAS by Sarah Ford]

OSUT :
One Station Unit Training; being a combination of basic (BCT) and advanced (AIT) training, where a soldier remains in the same unit for both portions of instruction; similar to the CADRE system employed during WWII where the parent unit was responsible for training all of its own members.

BILTMORE OSWALD :
a humorous character created by James Thorne Smith Jr., son of a U.S. Navy commodore and WWI veteran, who was then editing the Navy newspaper "Broadside"; the stories about this accident-prone would-be sailor were collected into a book, "Biltmore Oswald: The Diary of a Hapless Recruit" (1918), whose misadventures proved so popular after the war that another volume of stories was published, "Out 'o Luck: Biltmore Oswald Very Much at Sea" (1919). Thorne Smith, who also published a book of poetry, is best known for writing "Topper: An Improbable Adventure" (1926) and "Topper Takes a Trip" (1932), "Night Life of the Gods" (1931), "Turnabout" (1931), "The Big Book of Alcoholics Anonymous" (1939), and two posthumous releases "I Married a Witch" (1941) and "Bats in the Belfry" (1943), which spawned the TV series "Bewitched", "I Dream of Jeannie", and "My Living Doll" during the 1960s. Smith said of his work: "Like life itself, my stories have no point and get absolutely nowhere. And like life they are a little mad and purposeless. Quite casually I wander into my plot, poke around with my characters for a while, then amble off, leaving no moral proved and no reader improved." See FICTIONAL CHARACTER.

OTH :
an Other Than Honorable discharge from military service; see DISCHARGE.

a distant station or POST that's been established to protect the main force (or the nation) from surprise attack, generally situated in a foreign environment; see COP, OP, CP, FOB, FSB, LSA, BASE CAMP, COMPOUND, CROW'S NEST, DEW LINE, NATURAL AREA. [nb: "But the turning and surrounding a small fraction of the enemy, and particularly in the darkness of night, is also more practicable for this reason, that whatever we stake upon it, and however superior the force used may be, still probably it constitutes only a limited portion of our army, and we can sooner stake that than the whole on the risk of a great venture. Besides, the greater part or perhaps the whole serves as a support and rallying-point for the portion risked, which again very much diminishes the danger of the enterprise. Not only the risk, but the difficulty of execution as well confines night enterprises to small bodies. As surprise is the real essence of them so also stealthy approach is the chief condition of execution: but this is more easily done with small bodies than with large, and for the columns of a whole army is seldom practicable. For this reason such enterprises are in general only directed against single outposts, and can only be feasible against greater bodies if they are without sufficient outposts, ...." by Karl von Clausewitz]

OUTRIGGER :
slang for the supporting and balancing TRAIL on a TOWED cannon or other artillery piece when LIMBERed for travel or UNLIMBERed for firing; also called "outrigger legs"; see ARTY.

parachute badge background
trimming for 509th Airborne Brigade parachute badge background
trimming for 3rd Bn 504th Parachute Infantry Regiment parachute badge background
trimming for 11th Airborne Division
background trimming for para wings
the informal term for the background trimming for PARACHUTE WINGS, being a distinctively colored and patterned PATCH worn behind the parachutist's badge when the PARATROOPER is assigned to a unit on jump status. Originating during WWII to increase the perceived size of para-WINGS, which was commonly believed to be too small by contrast with PILOT's WINGS, it became a designator for active jump status when permanent wear of the WINGS was permitted, regardless of AIRBORNE standing. The OVAL is sometimes "humped" to include the gradations of Senior and Master ratings; and the entire badge (OVAL and WINGS) may sometimes be a single embroidered PATCH (especially in the Far East where custom tailoring was inexpensive). Depending upon historic tradition and unit evolution, the OVAL will not always match the color or pattern of the same unit's beret FLASH (eg: 5th SFGAbn). The distinctive OVAL and FLASH patches are collectively known as "FLASHing". AIRMOBILE units are not authorized "FLASHing". Navy and Marine personnel on jump status do not wear OVALs. Compare JSD; see Q-COURSE, Q-TAB, TRASH. [v: Flashing Sampler]

OVER :
a procedure word (PROWORD) meaning 'transmission temporarily completed' that's used in radio/telephone procedure (RTP) to make voice communications more concise and clear; it implies that the station remains atuned and waiting so that further communication is possible, and it is mutually exclusive with OUT. [nb: 'clear' means that communication is finished but the station is standing-by for more traffic (finished sending, able to receive); 'break' means that this communication is finished but this station is changing channels for further communication (still sending, unable to receive)]

OVER A BARREL :
an awkward or untenable position, being one from which extrication is difficult or impossible; as derived from a corporal punishment practiced in earlier times, where the offender was bound across the barrel of a cannon (not a staved container, but the tubelike part of a gun) preliminary to lashing for an infraction of military regulations. See PAIN; compare GAUNTLET, KEELHAUL, GARROTE, DEATH OF A THOUSAND CUTS, TWIST IN THE WIND, BELL THE CAT. [nb: apparently civilians adopted variations of this punishment, including humiliating college hazings, where victims were bound helpless to a wooden barrel (a staved container) for assorted torments, not unlike being locked in a pillory or stocks for public derision] [nb: a 19th century Navy expression for a formal flogging with the cat-o'-nine-tails as ship's punishment was: "dance at the gratings"; while a Navy version of the pillory or stocks, known as "kiss the wooden lady", bound a sailor facing the mast for fatigue punishment and intermittent or random kicks to his buttocks by shipmates]

OVER 'n' UNDER :
prototype of M-203 grenade
launcher attached to M-16 rifle
XM-148
despite this phrase being indicative of a SHOTGUN configuration, it is slang for the XM-203, introduced as XM148 into the field in 1970, which hung a single-shot 40mm "bloop tube" grenade launcher barrel under the foregrip of the M-16 rifle, which impaired the balance and accuracy of both weapons. An experimental style "pump M-79", with a five-round tube-magazine below the barrel, was selectively issued to LRRP and SPECIAL OPERATIONS teams in Vietnam. In 2006, all versions of the single-shot grenade launcher were superseded by the M-32 Multiple-shot Grenade Launcher (MGL) for infantry operations. See BLOOPER, THUMPER, BLACK MAGIC, WIDOW MAKER, POODLE SHOOTER, TUPPERWARE, ACTIV. Also, any double-barreled shoulder arm, configured one barrel above the other, as with shotguns or combination guns; see the Aircrew Survival Weapon (ASW) or M-6 SCOUT. [cf: the LeMat revolver was a double-barreled nine-shot pistol that was developed by Jean A.F. LeMat, a New Orleans physician, in 1856 for close combat by naval and cavalrymen; chambered for .40 caliber and 18 gauge, it was preferred by Confederate generals J.E.B. Stuart and P.G.T. Beauregard]

OVERHEAD :
a ceiling-like covering of the exposed support members for above the compartment; see DECK, BULKHEAD, HATCH.

OVERKILL :
to extirpate more of the enemy, or to cause more destruction, than is absolutely necessary for a military victory; this term implies wanton devastation and needless COLLATERAL DAMAGE. Term seems to have originated after the atomic bombings of WWII, but utterly fails to note historic examples of greater devastation and annihilation; see CBR, WMD, NUKE, BOMB 'EM BACK TO THE STONE AGE, BOUNCE THE RUBBLE, UP-GUN, OUTGUN, ROMAN HOLIDAY, NOT ONE STONE LEFT UPON ANOTHER, KNOCK INTO A COCKED HAT, MASSACRE, HEADHUNTING, TURKEY SHOOT, KILL 'EM ALL, ATROCITY, GENOCIDE, HOLOCAUST [eg: Albi, Atlanta, Baharestan Square, Beziers, Carthage, Chatham Islands, Columbia, Covington, Dresden, Glencoe, Guernica, Hiroshima, Katyn, Lidice, Meroë, Nagasaki, Nanking/Nanjing, Shanghai, Sybaris, Tiananmen Square, Veii].

OVERSEAS BAR :
a service stripe worn on the lower right sleeve of the CLASS-A uniform, each representing six-months of foreign duty served in a combat zone; this service stripe, commonly known as a HERSHEY BAR(qv), replaced the WWI-era overseas chevron that was worn in the same manner. See OCONUS, DEROS, WHEN IN ROME, DUC, PH. [nb: an OVERSEAS BAR should never be confused with exotic drinking establishments outside CONUS or with foreign legalities, no matter how much the former involves the latter] [nb: civilians go 'abroad' while soldiers go 'overseas']

OVERSEAS CAP :
the GARRISON CAP or garrison hat that was adopted for troops in France during WWI as a more convenient replacement for the CAMPAIGN HAT when not wearing a helmet; also known as a "Go To Hell" cap, fore 'n' aft cap, flight cap, boat cap, flat cap, envelope cap, pisscutter, or CUNT CAP. Compare BILLED CAP, SAUCER CAP, CRUSHER; see HEADGEAR. [nb: a Balmoral hat, which somewhat resembles a beret, and is traditionally blue (from the campaigning dress of the Blue Bonnets), and is often accented with a surrounding "diced" pattern (called "checky" after an accounting process of the Stewarts or High Stewards, from which "exchequer" derives) that symbolizes guardianship and protection; the boat-shaped Glengarry hats are of 19th century military origin]

OVERSEXED WEEKLY :
nickname of the "Overseas Weekly", an unaffiliated newspaper that was published from 1950 to 1975 in various theater editions [ie: Europe (c1950), Asia (c1966), America (c1970)] as a representative of the alternative press. Being "the enlisted man's newspaper in contemporary times", and calling itself "the only overground-underground paper", it appealed to a youthful readership with sensational reportage, but attracted the ire of officialdom (eg: banned by SecDef Robert S. McNamara; ban later rescinded by the Supreme Court) for the accuracy of its exposés. This populist weekly supported the rights of servicemembers, regardless of race or religion, against the abuses of power inflicted by crazed or bigoted officers (eg: the lieutenant colonel who dressed his twelve-year-old son in a military uniform to help conduct troop inspections). The métier of this independent tabloid was titillation, from lurid court martial testimony and come-on headlines to ribald humor and pin-ups, which were leavened by sports and lifestyle features for the edification of its servicemember readership. Founded by Marion von Rospach, a companion publication ["Overseas Family" (c1959)] was also produced in Germany. The "Overseas Weekly" is proud of never having lost a libel suit, and never having been charged with any act harmful to the United States [cf: Pentagon papers in NYT (1971)]. Compare STARS AND STRIPES, YANK, JOURNAL. [nb: "We have Communists and we have the Overseas Weekly. Neither is one of God's blessings to the American people or their soldier sons overseas. Immoral, unscrupulous, corrupt and destructive are words which could be applied to either." by MG Edwin Walker (1961)] [nb: "Army Times", "Navy Times", "Air Force Times", "Marine Gazette", "Early Bird Brief", "Daily News Roundup", and other service-oriented newspapers are proprietary publications, just as "Army", "Leatherneck", "Sea Power", "Air Power", "National Guard", "Legion", "VFW", and other quasi-military magazines are proprietary publications of their respective professional or veteran associations, which are neither endorsed nor sponsored by the military]
