IMT :
International Military Tribunal. The London Agreement between the Allied representatives of the Soviet Union, Great Britain, France, and America on 8 August 1945 sponsored Law Ten of the Allied Control Council, which instruments authorized the Charter of the International Military Tribunal, and established its methodology. The Charter of the IMTribunal authorized the trial of wartime suspects whose acts crossed national boundaries; while suspects whose acts were localized were to be tried separately by the Occupation Zone nation having jurisdiction. All four of these war crimes' courts operated according to its own national procedures, but each was governed by the IMT Charter. The IMT was based in Berlin, located in the USSR Occupation Zone, and the IMT trials were convened in November 1945 at the Palace of Justice in Nuremberg, situated in the US Occupation Zone. Each Occupation force appointed a judge, a judicial alternate, a prosecutor, and a prosecutorial staff, while the defendants chose their own legal counsel. The charges brought were: conspiracy to wage aggressive war; waging of aggressive war in violation of treaties; war crimes; and crimes against humanity. Twenty-two defendants and eight organizations were charged, resulting in guilty verdicts for nineteen convicts (12 hanged, 7 incarcerated, 3 acquitted), and four organizations. The IMT heard appeals after sentencing, and disbanded on 16 October 1946 as soon as the sentences were executed. See IMTFE, ICC, UNWCC, ROE, WAR CRIMES TRIAL, HAGUE TRIBUNAL, LAWS OF WAR; compare UCMJ. [nb: "That four great nations, flushed with victory and stung with injury, stay the hand of vengeance and voluntarily submit their captive enemies to the judgement of the law, is one of the most significant tributes that power has ever paid to reason." by Robert D. Jackson in an opening statement at Nuremberg] [nb: the prosecutors in the 1942 "Pastorius" Nazi saboteurs' trial respectively became the chief justices of the WWII war crimes trials of Axis defendants: Attorney General Francis Biddle was senior US judge at Nuremberg, and Army Judge Advocate General Myron C. Cramer was the US judge at Tokyo] [v: mittimus]

IMTFE :
International Military Tribunal for the Far East. The IMTFE was conducted in Tokyo from 3 May 1946 to 12 November 1948 by judges and prosecutors from each of the eleven Allied nations: Australia, Canada, China, France, Great Britain, India, the Netherlands, New Zealand, the Philippines, the Soviet Union, and the United States of America. The IMTFE Charter was written by General Douglas MacArthur, the Supreme Allied Commander, and Joseph Keenan, the US chief prosecutor. The indictment accused the defendants of promoting a scheme of conquest that "contemplated and carried out ... murdering, maiming and ill-treating prisoners of war [and] civilian internees ... forcing them to labor under inhumane conditions ... plundering public and private property, wantonly destroying cities, towns and villages beyond any justification of military necessity; [perpetrating] mass murder, rape, pillage, brigandage, TORTURE and other barbaric cruelties upon the helpless civilian population of the over-run countries." Of the eighty Class-A war criminal suspects detained in Sugamo prison after 1945, twenty-eight were brought to trial before the IMTFE. The accused included nine civilians and nineteen military professionals. Unlike the IMT, all the defendants were found guilty; with two defendants dying of natural causes, seven executed by hanging, sixteen sentenced to life imprisonment, two to lesser sentences, and one incarcerated in a mental institution ... all survivors had been paroled by 1956. In a separate trial, conducted 25-30 December 1949, twelve Japanese from the top-secret TAMA Detachment, who had been accused of bacteriological experiments on prisoners in Manchuria, were convicted by the USSR. See ICC, IMT, UNWCC, WAR CRIMES TRIAL, HAGUE TRIBUNAL, LAWS OF WAR, ROE; compare UCMJ. [nb: the prosecutors in the 1942 "Pastorius" Nazi saboteurs' trial respectively became the chief justices of the WWII war crimes trials of Axis defendants: Attorney General Francis Biddle was senior US judge at Nuremberg, and Army Judge Advocate General Myron C. Cramer was the US judge at Tokyo] [v: mittimus]

IN COUNTRY :
the designated hostile area, specifically Vietnam, but not the geographic limit of the war; also spelled "in-country". Compare OUT COUNTRY; see INDOCHINA.

INCURSION :
the hostile entry of a place, or the military penetration of a territory, as an expeditionary raid or inroad for defined or limited objectives; as distinguished from an INVASION for enduring conquest or perpetual occupation. [v: anabasis; cf: katabasis, excursion] [nb: the Cambodian INCURSION (30 April - 30 June 1970) was limited to 30kn from the SVN border; as SOG missions were restricted to 20km inside Laos and Cambodia]

INDIAN COUNTRY :
hostile territory, especially in the field or jungle, as any areas contested by the enemy remote from BASE CAMPs or cities; see BOONIES, THULE, DOWN RANGE, SANDBOX.

See STACK, COMBAT SPREAD, ACCORDION, CATERPILLAR, HEADWAY; compare COLUMN.

INDIAN WARS :
a general term referring to the series of conflicts, under the tenets of Manifest Destiny, between European immigrants and the indigenous peoples of North America; ranging from the 1680 Pueblo Uprising, the 1637 Pequot War, the 1675-7 Wampanoag and Narragansett Uprising (King Philip's War), Pontiac's Rebellion in 1763, the Battle of Fallen Timbers in 1794, defeat of the Shawnee prophecy at Tippecanoe in 1811 (and the demise of the Shawnee Confederacy with the death of Tecumseh in the 1813 Battle of the Thames, and the defeat of their British ally in the WAR OF 1812), the 1814 defeat of the Creek Confederation, the 1832 Black Hawk War (caused by the forced removal of the Sac and Fox to the Indian Territory west of the Mississippi River), but most especially the battles fought after 1860 on the Frontier (Great Plains and Far West) against the Sioux, Apache, Comanche, Cheyenne, Arapaho, Kiowa, Ute, Blackfoot, Shoshone, Nez Percé, and Bannock tribes. Hostilities reached their peak between 1869-78 when more than 200 battles were fought; notable incidents include the Siege of Tucson, the Massacre at Sand Creek, the Modoc War, the Fetterman Massacre, the Battle at Little Bighorn, and the Battle of Wounded Knee. The 1890 Battle of Wounded Knee is usually considered to be the closing encounter of the INDIAN WARS, although there was an expedition against the Ojibwa in Minnesota in 1898. At the end of this era, the AmerIndian was confined on reservations. [v: after the surrender of the Apaches, the surviving tribesmen, including women and children, all classified as POWs, endured a 30-year imprisonment on various remote Army posts (eg: "The Long Walk")] [nb: in an effort to economize after the CIVIL WAR, Congress mandated that each Spencer repeater be retrofitted with the Stabler Cut-off Device, which modification converted the 7-shot carbine into a single-shot firearm, until combat losses in the INDIAN WARS forced its abandonment, and later succession of the Spencer by the trapdoor Springfield having even more firepower]

INDIG :
(indidge) contracted form of INDIGenous, as a reference to the native peoples of a region or locale who may be divided in their loyalties by race, creed, religion, and other criteria. In Southeast Asia during the VIETNAM WAR, numerous partisan factions and ethnic tribes participated in Allied operations, including Bahnar, Bru, Cao Dai, Cham, Chinese, Cua, Halang, Hmong/Meo, Hoa Hao, Hre, Hroi, Jarai, Jeh, Katu, Kha, Khmer, Koho, Ma, M'nong, Muong, Nung, Raglai, Rengao, Rhade, Sedang, Stieng.

[cf: aborigine, autochthon, native, denizen, inhabitant, countryman, compatriot, citizen, CIVILIAN, ALLY]

INDOCHINA :
the region of Southeast Asia (SEA), between the Bay of Bengal and the South China Sea, comprising Vietnam, Cambodia, Laos, Burma (Myanmar), Thailand, western Malaysia, and boundary islands (eg: Paracels). Scottish poet and Orientalist John Leyden proposed the referent INDOCHINA during the early 19th Century, because the region lay between India and China, and its history was tied to both dominant influences. Popularized by Bernard Fall, who is also credited with designating the native rebellion against British, French, and American forces as the Second Indochina War. Also, the name of the former (1862-1954) French colonial federation, French INDOCHINA (Indo-Chine = Extreme Orient) or "Union Indochinoise", now comprised of Laos, Cambodia, and Vietnam; Vietnamese version : "Dong Nam A". Compare ANNAM, COCHIN CHINA, TONKIN. [nb: During the First through Fifth Centuries, most of southeast Asia was dominated by Funan, which included most of present Thailand, Laos, Cambodia, and the Mekong delta region of Vietnam. Funan was supplanted around the Sixth Century by Chenla. Annam was a small coastal strip in north VN and southern China, and south of it Champa controlled a coastal strip in central VN. Pressure from China pushed Annam southwards, and in turn Annam pushed Champa south to what is now roughly central South Vietnam. In 1284, Kublai Khan leads a 500,000-man Chinese army into Vietnam, but guerrillas organized by Tran Hung Dao virtually destroy the INVASION force. Around the Twelfth Century the Khmers emerged as a great empire controlling all the lower Mekong, leaving Sukhothai as a small version of modern Siam and Laos. From 1407 to 1428, China seized control of Dai Co Viet, but resistance forces led by Le Loi drove the Chinese from the country, and established the kingdom of Dai Viet; so that by 1428, Vietnam regained her independence from China's Ming Empire. The Khmer Khmer Empire collapsed after Siam seized Ankor in 1431. Thereafter, Cambodia found itself pinched between its more powerful neighbours: Siam and Annam. In the late 18th and early 19th Centuries, much of Cambodia was partitioned between Siam and Annam. In 1844, what was left of Cambodia became a protectorate of Siam. Around the 15th Century the Kingdom of Luang Prabang emerged along the upper and middle Mekong River. Vientiane and the middle Mekong broke away in 1707. Both Luang Prabang and Vientiane came under Siamese suzerainty in 1778. During most of its existence, Laos was disputed over by Siam and Annam. Laos did not reemerge as a distinct and separate entity until the French declared this region a protectorate in 1893. Annam expanded farther southward into Champa in the 16th Century, and into the Mekong Delta in the 18th Century. With its capital at Hue, Annam seized Saigon in 1776. With French advice and assistance, Annam defeated the Tay Son triumvirate, and united the Tongking and Cochinchina regions into the Vietnamese Empire in 1802; but the Cochin, Annam, and Tongking regions were administered separately. Following religious persecutions, France seized Saigon in 1861, and annexed Cochin in 1862. Cambodia became a French protectorate in 1863, and Siam gave up its claims to the area in 1867. The French then made protectorates of Annam and Tongking in 1884, and unified the protectorate into the "Union Indochinoise" in 1887, retaining the capital at Saigon. Laos was added to this union when it became a French protectorate in 1893. After further confrontations, Siam ceded more territory, which France added to Cambodia and Laos in 1907. After the Nationalist Chinese and British reinstated the French protectorate on 19 Dec 1946, with Bao Dai as nominal emperor, the Second Indochina War began.]

INF :

[v: Joseph Hooker's Bureau of Military Information] ["Thus, what enables the wise sovereign and the good general to strike and conquer, and achieve things beyond the reach of ordinary men, is foreknowledge [of the enemy's disposition and intentions]. Now this foreknowledge cannot be elicited from spirits; it cannot be [predicted] obtained inductively from experience, nor by any deductive calculation. Knowledge of the enemy's dispositions can only be obtained from other men." by Sun-Tzu]

IOTV :
Improved Outer Tactical Vest; individual body armor introduced in 2007 to replace the "Interceptor" Outer Tactical Vest from the late 1990s. The Improved Outer Tactical Vest is an over-the-head entry FLAK VEST, with a mesh liner for wicking and an inner cummerbund for weight distribution, available in eleven sizes that incorporate a lower back flap to increase ballistic coverage. The IOTV has integrated side ballistic plate carriers to accommodate currently-issued Enhanced Small Arms Protective Insert plates in the front, back, and sides, obviating the need for the Deltoid Axillary Protector set. Soldier survivability is enhanced by a single-point quick release tab on the front of the vest that pulls it apart into several pieces with one tug, as well as tear-away access points for medical treatment. The 27 pound IOTV (weighing 3#s less than the "Interceptor" Outer Tactical Vest) offers a reduced profile for increased mobility during operations.

IRC :
the International Rescue Committee was setup during 1933 by a group of 51 concerned Americans (including John Dewey, Charles A. Beard, Morris Cohen, Roger Baldwin, John Dos Passos, Abba Hillel Silver, Oswald Garrison Villard, Reinhold Niebuhr, and William J. "Wild Bill" Donovan) who responded to a plea for action by Albert Einstein. Established in imitation of the Europe-based International Relief Association, the objective of the International Rescue Committee (IRC) was to save anti-Nazi leaders targeted by the Gestapo by guiding them to safety in free countries. The refugee tide grew in 1938 as thousands escaped from Fascist Italy and Franco's Spain, then surged in 1939 when the infamous Nazi/Soviet pact led to the invasion and partition of Poland, and the beginning of WWII. When France fell, the refugees had to flee again, so a new American organization, called the "Emergency Rescue Committee", sent volunteers to establish escape routes, many of whom later joined the underground resistance. The end of the war left a devastated continent with millions of uprooted people on the move: prisoners of war, displaced persons (DP), forced laborers, expellees, concentration camp survivors, and refugees. In order to provide the most effective assistance for them, the International Relief Association and the Emergency Rescue Committee joined forces to become the International Rescue Committee, serving refugees of all religions, races, and nationalities. With the onset of the Iron Curtain, the IRC's relief and resettlement efforts shifted, establishing hospitals and children's centers funded by a combination of public and private monies. The IRC has served the emergency relief needs, as well as some extended health and education goals ("One doctor can save a thousand lives and one teacher can save a thousand minds."), of refugees and exiles from "hot spots" scattered around the world. Its resettlement methodology for Indochinese BOAT PEOPLE has become the model for other agencies and organizations. [nb: "There is so much injustice and suffering crying out for our attention: Victims of hunger, racism and political oppression, prisoners of so many lands, governed by the Left and Right. What all these victims need above all is to know that they are not alone: that we are not forgetting them; that when their voices are stifled, we shall lend them ours; that while their freedom depends on ours, our quality of freedom depends on theirs." by Elie Wiesel; "Support of the principle of asylum, and assistance for refugees, are fundamental principles of American foreign policy." by Dwight David Eisenhower] See PEACE CORPS, IVS, SPARTAN, CA, ADV, E&E, BRIGHT LIGHT, SAFE, BLOOD CHIT, DP, BOAT PEOPLE, YELLOW BIRD. [nb: the parent organization of the American Red Cross, being the International Red Cross based in Geneva Switzerland, should not be confused with the International Rescue Committee (IRC), despite their cooperation]

IR MARKERS :
American and NATO military rotary- and fixed-wing aircraft are marked with infrared (IR) patches in distinctive patterns on the fore (near cockpit) and aft portions of the fuselage, and on the wings or rotor blades, which serve as positive identification whenever flying in BLACKOUT conditions prohibits the use of colored navigation lights or IFF/SQUAWK recognition aids. See STARBOARD, PORT, AFT, STERN, BOW, PROW, STEM, WEFT, SCRAM, CHOPPER, BIRD.

IRON BOMB :
any conventional gravity ordnance or "dumb bomb", also called an "egg", including time delay and proximity, explosive and incendiary, weighing from 100# to 2000#, and delivered on target by aircraft subject only to the laws of physics. See STICK, BUTTERFLY BOMB, FAE, CBU, GBU, SNAKE, SNAKES 'n' NAPES, NAPALM.

IRON CURTAIN :
a political and ideological barrier that impeded relations between the Soviet Union (USSR) and its allies (Warsaw Pact) and other non-communist countries; phrase used by Winston Churchill in 1946 to describe the line of demarcation between Western Europe and the Soviet zone of influence. Also, an impenetrable barrier to the exchange of information and ideas, to communication and understanding, as imposed by rigid censorship and secrecy. Compare STAR WARS, MAGINOT LINE, SMEZ, BERLIN WALL, BAMBOO CURTAIN, BAR LEV LINE, CACTUS CURTAIN, McNAMARA'S WALL, McNAMARA LINE, CHINESE WALL, DEW LINE, PHASE LINE. [cf: Hadrian's Wall, Antonine Wall, Great Wall of China] [nb: "The strength of a wall is neither greater nor less than the men who defend it." by Genghis Khan]

IRON MIKE :
paratrooper statue, dedicated in tribute to WWII combat parachutists ["In honor of the American Airborne Trooper, whose courage, dedication, and traditions make him the world's finest fighting man."], and serving as a paradigm for subsequent AIRBORNE personnel, has been emplaced at Fort Bragg since 1961. The IRON MIKE statue was inspired by the cover illustration on Those Devils in Baggy Pants by Ross Carter (504/82 Abn Div), was modeled by SGM Mike Runyon (1960), and was sculpted in steel and fiberglass resin by Leah Hiebert, an artist and wife of LTC Samuel L. Hiebert (then Deputy Post Chaplain). IRON MIKE represents a paratrooper ready for action shortly after landing, depicting the courage, dedication, weariness, and compassion characteristic of veterans. This icon complements the infantryman and doughboy statues at other posts. [nb: 'statue' derived from 'status', meaning 'standing', 'position'] [nb: not to be confused with John W. "Iron Mike" O'Daniel, CG of 3rd Inf Div in WW2 and MAAG-VN]

IRON RATIONS :
a small supply of emergency food, also called survival rations; see BULLY SOUP, BEANS, CHOW, C-RATIONS, SOUP, SOLDIER'S BREAKFAST, GI JOE, BUG JUICE, FORAGE, RATIONS. [nb: despite the perennial complaints about military food, and some rude characterizations (eg: biscuit = armor-plate), this designation does not describe the texture or taste of survival rations!] [cf: pemmican]

IRON TRIANGLE :
an enemy sanctuary in III CORPS region near Ben Suc; adjacent to WAR ZONE C. See CEDAR FALLS.

IROQUOIS :
Bell UH-1 utility helicopter series; NICKNAMEd HUEY, from its "UH" designation, and became symbolic of the VIETNAM WAR through photojournalism. The Bell UH-1 helicopter is one of aviation's true success stories. Thousands of the aircraft have been made in a number of variations, serving a multitude of roles. Bell was chosen in 1955 to provide the army with a utility helicopter capable of serving as a FRONT LINE medical evacuation (MEDEVAC) aircraft, a general utility aircraft, and an instrument training aircraft. Deliveries to the U.S. Army began in 1959. In 1961 a more powerful version, the UH-1B, was introduced, and saw use by both Army and Marines in transport and as an early GUNSHIP. The UH-1C was used by the Army as an armed attack helicopter. In 1967, starting with the UH-1D series, the airframe length was increased, giving the HUEY a much roomier passenger-cargo compartment capable of carrying more troops or supplies. The UH-1F Bell helicopter was used by the Air Force as a light utility cargo or personnel carrier, and as a GUNSHIP. The UH-1N was an Army light helicopter. In 1968 Bell developed a specialized version of the aircraft with a stronger airframe and more powerful engine. The HUEY TUG, as it was NICKNAMEd, was capable of lifting loads up to three tons, nearly double that of a conventional HUEY. Powered by a 1,400 SHP Avco Lycoming engine, the HUEY had a cruising speed of 127 mph and a range of 318 miles. Fast and maneuverable, the HUEY proved far superior to the CH-21 SHAWNEE or CH-34 KINGBEE as an assault helicopter. Combat troops normally rode in the wide door openings on each side of the aircraft, and could exit quickly; greatly reducing the time the helicopter was on the ground. Often troops jumped from a HUEY just above the ground as it "bounced" in ground effect, with the entire ground time reduced to a matter of seconds. See SLICK, GUNSHIP, CHOPPER.

IRR :
Individual Ready Reserve; see WEEKEND WARRIOR, MILITIA.

IRREGULARS :

ITV :
(eye-tee-vee) abbreviation for Improved Tow Vehicle, being a mobile platform for firing TOW (Tube-launched Optically-tracked Wire-guided) missiles; similar to the earlier JEEP-mounted recoilless rifle (RR) anti-tank (AT) setup.

I2 :

IVAN :
NICKNAME for USSR soldier, also known as BULLSHITVIK or "Charlie Brown" for similar personality (serious and deliberate, but always messing-up); also known as "Russki", "Red", "Katsap", "Radish", or "Commie". Compare MARVIN THE ARVN, LUKE THE GOOK, CHARLIE, GOMER, HERMAN THE GERMAN, ISAAC THE IRAQ, SCARAB THE ARAB, FOE, BAD GUYS.

IVS :
abbreviation for International Voluntary [Volunteer] Service; a QUANGO formed in 1956, which served as the model for the PEACE CORPS, and was finally dissolved in 2003 by insufficient funding. IVS operated worldwide, attracting idealistic and dedicated young adults, often religious, who wanted an opportunity to improve living conditions in remote areas. It sometimes received service, aid in kind (AIK), or funding from USAID or USDAO. Composed of civilian advisers and teachers in technical (medical or agricultural) fields, these volunteers served the needs of INDIGenous peoples. During the VIETNAM WAR, the VC/NVA made no distinction between armed and unarmed advisers, and several IVS volunteers were deliberately captured or killed in order to politicize their acts. See ADV, CA, CAP, COUNTERPART, LITTLE BROWN BROTHER, INDIG, SPARTAN, IRC, AMERICAN FRIENDS SERVICE COMMITTEE, DRAFT LOTTERY. [nb: civilians go 'abroad' while soldiers go 'overseas']
