Combat Identification Panel
The Combat Identification Panel (CIP), also known as a Coalition Identification Panel, is an Identification friend or foe device mounted on military ground vehicles used by United States Armed Forces' United States Army with United States Marine Corps and its allies to distinguish them from the enemy during battle. History Combat Identification Panels were developed after the Persian Gulf War to reduce friendly fire incidents among allied ground forces. These panels are designed to produce a distinct and easily identifiable infrared signature when seen through thermal imaging systems. Originally created as a hasty expediency, the use of low-thermal-emissivity tape and physical separation from the body of the vehicle meant that the panel would appear as a contrasting dark (i.e. cooler) area through thermal viewers. CIPs first saw widespread use in the Iraq War where nearly all coalition vehicles were equipped with these devices, usually mounted on the sides and rear of the body ...

Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

Invasion Stripes
Invasion stripes were alternating black and white bands painted on the fuselages and wings of Allied aircraft during World War II to reduce the chance that they would be attacked by friendly forces during and after the Normandy Landings. Three white and two black bands were wrapped around the rear of a fuselage just in front of the empennage (tail) and from front to back around the upper and lower wing surfaces. Background After a study concluded that the thousands of aircraft involved in the invasion (scheduled for June 6, 1944) would saturate and break down the IFF system, the marking scheme was approved on May 17, 1944, by Air Chief Marshal Sir Trafford Leigh-Mallory, commanding the Allied Expeditionary Air Force. A small-scale test exercise was flown over the OVERLORD invasion fleet on June 1, to familiarise the ships' crews with the markings, but for security reasons, orders to paint the stripes were not issued to the troop carrier units until June 3 and to the fighter ...

Clapboard (architecture)
Clapboard (), also called bevel siding, lap siding, and weatherboard, with regional variation in the definition of those terms, is wooden siding of a building in the form of horizontal boards, often overlapping. ''Clapboard'', in modern American usage, is a word for long, thin boards used to cover walls and (formerly) roofs of buildings. Historically, it has also been called ''clawboard'' and ''cloboard''. In the United Kingdom, Australia and New Zealand, the term ''weatherboard'' is always used. An older meaning of "clapboard" is small split pieces of oak imported from Germany for use as barrel staves, and the name is a partial translation (from , "to fit") of Middle Dutch and related to German . Types Riven Clapboards were originally riven radially by hand producing triangular or "feather-edged" sections, attached thin side up and overlapped thick over thin to shed water.

Humvee
The High Mobility Multipurpose Wheeled Vehicle (HMMWV; colloquial: Humvee) is a family of Military light utility vehicle, light, four-wheel drive Military vehicle#Military trucks, military trucks and utility vehicles produced by AM General. It has largely supplanted the roles previously performed by the Willys MB, original jeep, and others such as the Vietnam War-era M151 ¼-ton 4×4 utility truck, M151 Jeep, the M561 "Gama Goat", their M718A1 and M792 ambulance versions, the Commercial Utility Cargo Vehicle, and other light trucks. Primarily used by the United States military, it is also used by numerous other countries and organizations and even in civilian adaptations. The Humvee saw widespread use in the Gulf War of 1991, where it navigated the desert terrain; this usage helped to inspire civilian Hummer versions. The vehicle's original unarmored design was later seen to be inadequate and was found to be particularly vulnerable to improvised explosive devices in the Iraq Wa ...

Iraq War
The Iraq War (), also referred to as the Second Gulf War, was a prolonged conflict in Iraq lasting from 2003 to 2011. It began with 2003 invasion of Iraq, the invasion by a Multi-National Force – Iraq, United States-led coalition, which resulted in the overthrow of the Ba'athist Iraq, Ba'athist government of Saddam Hussein. The conflict persisted Iraqi insurgency (2003–2011), as an insurgency arose against coalition forces and the newly established Iraqi government. US forces Withdrawal of United States troops from Iraq (2007–2011), were officially withdrawn in 2011. In 2014, the US became re-engaged in Iraq, leading a new coalition under Combined Joint Task Force – Operation Inherent Resolve, as the conflict evolved into the ongoing Islamic State insurgency in Iraq (2017–present), Islamic State insurgency. The Iraq invasion was part of the Presidency of George W. Bush, Bush administration's broader war on terror, launched in response to the September 11 attacks. ...

A Challenger 2 Crosses Into Iraq
A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is '' a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, '' a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest known ancestor of A is ''aleph''—the first letter of the Phoenician ...

Thermal Imaging
Infrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals becom ...

Friendly Fire
In military terminology, friendly fire or fratricide is an attack by belligerent or neutral forces on friendly troops while attempting to attack enemy or hostile targets. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack enemy or hostile targets, and deliberate firing on one's own troops for disciplinary reasons is not called friendly fire,Regan, Geoffrey (2002) ''Backfire: a history of friendly fire from ancient warfare to the present day'', Robson Books and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting. Use of the term ''friendly'' in a military context for allied personnel started during the First World War, often when shells fell short of the targeted enemy. The term ''friend ...

Multi-National Force – Iraq
The Multi-National Force – Iraq (MNF–I), often referred to as the Coalition forces, was a U.S.-led military command during the Iraq War from 2004 to 2009. The vast majority of MNF-I was made up of United States Army forces. However it also supervised British, Australian, Polish, Spanish, and other countries' forces. It replaced the previous force, Combined Joint Task Force 7, on 15 May 2004. It was significantly reinforced during the Iraq War troop surge of 2007. MNF-I was reorganized into its successor, United States Forces – Iraq, on 1 January 2010. The United Nations Assistance Mission for Iraq, which does humanitarian work and has a number of guards and military observers, has also operated in Iraq since 2003. The U.N. Assistance Mission in Iraq was not a part of the MNF-I, but a separate entity. The NATO Training Mission – Iraq, was in Iraq from 2004 to December 2011, where it trained the Iraqi Army and the Iraqi Police. History The MNF-I's objectives, as ...
