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.

OATH :
a solemn appeal to a deity, or to some revered person, entity, or thing, to witness a person's determination to speak the truth or keep a PROMISE; any statement, troth, or affirmation accepted as the equivalent of such an appeal.

[nb: 'gee' and 'gee-whiz', used as an interjection or exclamation, derive as euphemisms for the name "Jesus"; archaic 'zounds' derived as contraction of "God's wounds"; "blimey" or "gorblimey", used as an interjection or exclamation, derive as a reduction of "God blind me"; 'hooey', allegedly an Americanism used as an interjection for nonsense or tripe, is actually a corruption of the Russian vulgarity ("khuy") for penis, and is commonly used alone (eg: dick, dickhead, dick-wad) or in phrases (eg: dumber than dick; he doesn't know dick; don't dick around; don't stir your tea with your dick; don't dip your dick in the soup)] [cf: migration of "putz" from shine through ornament to penis and dolt; as sexual lure] [v: lucky stiff] [Swearing is either juvenile or crass, but MIL-PERS admire talent and respect skill, so creative vulgarity and uncommon scurrility is often appreciated. "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]

OB :
(oh-bee) Order of Battle, the identification, strength, command structure (arrangement), and disposition of the personnel, units, and equipment of military forces; known as Order of Battle Echelon (OBE) by Naval personnel, and compiled by Order of Battle Study (OOBS); compare TO&E/TOE, MTOE [cf: battalia]. Also, the abbreviation for Operations Base; see FOB.

OBJ :
OBJective, being the TARGET or goal, destination or end-point of an operation, usually denoted by code word or reference point (RP); see AIMPOINT, PHASE LINE, WAY POINT, SOFT TARGET, HARD TARGET, COLLATERAL DAMAGE.

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. [cf: vitalism, dynamism, mechanism, automatism; v: objectivity, objectivism, objective idealism, objective relativism, reification]

OBSTACLE COURSE :
a training course consisting of a series of physical barriers which must be negotiated by troops in a race against time; used for physical training (PT), and for familiarization with the tactical movements that might be encountered on a battlefield. 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.

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 safety and security; see KNOCK IT OFF, OPFOR, STOOGE, ALL'S FAIR IN LOVE AND WAR.

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, grogshop, watering hole, honky-tonk, dive, brasserie, bistro, taproom, beer joint, beer parlor, alehouse, rathskeller, cabaret, nightclub, drinkery]

OCOI :
Office of the Coordinator Of Intelligence/Information (COI) was the predecessor, along with the JCS Office of War Information (OWI), of the Office of Strategic Services (OSS) during WWII.

OCONUS :
(oh-ko-nus) Outside [of the] CONtinental United States; being MIL-SPEAK for overseas; includes assignments in Alaska and Hawaii. See HERSHEY BAR, DEROS; compare CONUS, ZI. [nb: civilians go 'abroad' while soldiers go 'overseas']

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 WAC OCS program was episodically offered until women were fully integrated into the Armed Forces in 1976. OCS during WWII 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 known as a "candidate" [or more formally an "officer candidate" (OC)], 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)]

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. 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)]

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. [v: dog days] [nb: "The sabbath was made for man, and not man for the sabbath." Mark 2:27 KJV Bible]

OFFHAND :

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 a 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]

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.

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 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 MOTHER-IN-LAW OF THE ARMY, CLASS-B DEPENDENT, CAMPAIGN WIFE, DISTAFF, BITCH, SKIRT, BRAT, 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. Servicemembers are excluded from some posted civilian establishments, and are confined 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", as without guidance.

OIF :
(oyef) Operation Iraqi Freedom, conducted from 19 March 2002 to 1 May 2003; sometimes called GULF WAR II or "Gulf War Part Two", and is sarcastically called the "Baghdad urban renewal project"; and also refers to the continuing WAR ON TERROR in the SANDBOX after the "mission accomplished" announcement that was supposed to be the "end of major hostilities", which is also referred to as "Operation Iraqi Freedom Part Two" or "OIF2" / "OIF II". Compare OEF; see GULF WAR, WAR ON TERROR. [v: Gulf War Supplement]

OLD WRIST BREAKER :
1860 light cavalry saber
cavalry saber
slang for the short and heavy saber issued to the U.S. Army cavalry (CAV) and mounted infantry (DRAGOON) until WWI, which was made of such inferior metal and so poorly tempered that it was impossible to sharpen; see LONG KNIFE, MAMELUKE SWORD. [v: Knife Terms; The Language of Swordplay]

OLYMPUS :
sardonic reference to the Oval Office in the White House, being short for Mount Olympus, the mythic abode of the gods; that realm where POTUS/CINC (Zeus) meets with the JCS (Titans) and other cabinet members. See GREEN ACRES, NSC, SECDEF, CHAIN-OF-COMMAND. [v: theomachy, gigantomachy, titanomachy]

Most MIL-PERS believe that 100 MPH TAPE is the greatest of all human inventions! See MUZZLE. [nb: in an effort to control costs and reduce waste, the DoD has instituted a policy of "non-duplication" in military procurement (Military Adaptable Commercial Item {MACI}), such that a mil-spec contract will NOT be let whenever a commercial "off the shelf" (COTS) product is "close enough for government work" and does not require special features; so some name brand items are now in logistical inventory]

101st ABN DIV (AMBL) :

[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!". An old military maxim states: "Deny your soldiers a proper bayonet and you will find a foreign one at your throat."]

OORAH :
(oo-rah, ouhr-rah) Marine Corps version of HOOAH, with the same spirit and meaning; apparently introduced by recon elements during the KOREAN WAR to express esprit, although earlier use of HOISE is a very credible antecedent for both OORAH and HOOAH. According to USMC FORCE RECON history, the 1st Amphibious Reconnaissance Company, then operating aboard a WWII-vintage diesel submarine in the KOREAN WAR theater, is credited with the invention of the call or salute OORAH, which was then pronounced "Aar-uugah", in imitation of the submarine dive warning alarm; since the 1st and 2nd Amphib Recon Co's were then deployed for raiding and surveillance from submarines, this call was both an alert and an acknowledgement of readiness for action. The veterans of these missions introduced this KLAXON sound to other Marines during stateside training after the war, and it spread ... becoming a PT chant as well as an enthusiastic affirmation.

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, 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]

OSS
(oh-ess-ess) Office of Strategic Services; sometimes called "Donovan's Dilettantes" and "Oh So Social". 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.

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.

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.

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 :
despite this phrase being indicative of a SHOTGUN configuration, it is slang for the XM-203, introduced 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.

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, 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]

OVERSIGHT :

slang for cross-border operations, which are typically covert or clandestine, except during HOT PURSUITs, interventions, or other INCURSIONs; also called "across the fence", "cross the line" (or "line crossing"), "over the wall", and "hop the fence". See DMZ, DEMILITARIZE, THE GREEKS, UNPFK / UNPIK (CCRAK), JACK, STD, SOG, SPECIAL OPERATIONS. [nb: Vietnamese term: Hanh Quan Vuot Bien] [nb: unlike the CIA and similar agencies, the military operates in foreign territory only under Department of Defense (DoD) and Department of State (DoS) sanctions, with operational security (OPSEC) providing "plausible deniability" for any classified operations]

OVER THE HILL :
an act of flight or abandonment, as to go or to have gone OVER THE HILL, with figurative or symbolic reference to any boundary; see AWOL, UA, DESERTER, MUTINEER, UCMJ, AWOL BAG. Also, informal reference to anyone too old or too unfit to "cut the mustard" (MUSTER), being a poor or pathetic example, an unworthy specimen, past one's prime; as a metaphor for someone who has reached his peak and is now on the downhill side of life's hill.

OVER THE TOP :
rash or impetuous, excessive or gross, extravagant or reckless behavior; ostensibly derived from the brave CHARGE of WWI troops advancing out of their trenches toward the enemy ... perhaps this attribution and re-interpretation has been made by a mistaken confusion between "dutiful courage" and "unfettered wildness" ... in any case, the modern meaning has completely distorted its origin.

OVERWATCH :
a supportive base of fire from heavy weapons during a maneuver.

OWI :
the JCS Office of War Information, being the predecessor, along with the Office of the Coordinator Of Intelligence/Information (OCOI), of the Office of Strategic Services (OSS) during WWII.
