Multispectral Camouflage
Multi-spectral camouflage is the use of counter-surveillance techniques to conceal objects from detection across several parts of the electromagnetic spectrum at the same time. While traditional military camouflage attempts to hide an object in the visible spectrum, multi-spectral camouflage also tries to simultaneously hide objects from detection methods such as infrared, radar, and millimetre-wave radar imaging. Among animals, both insects such as the eyed hawk-moth, and vertebrates such as tree frogs possess camouflage that works in the infra-red as well as in the visible spectrum. History The English zoologist Hugh Cott, in his 1940 book ''Adaptive Coloration in Animals'', wrote that some caterpillars such as the eyed hawk-moth ''Smerinthus ocellatus'', and tree frogs such as the red-snouted treefrog '' Hyla coerulea'', are coloured so as to blend with their backgrounds whether observed in visible light or in infra-red. Cott noted the importance of camouflage in the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Camouflage
Military camouflage is the use of camouflage by an armed force to protect personnel and equipment from observation by enemy forces. In practice, this means applying colour and materials to military equipment of all kinds, including vehicles, ships, aircraft, gun positions and battledress, either to conceal it from observation ( crypsis), or to make it appear as something else (mimicry). The French slang word ''camouflage'' came into common English usage during World War I when the concept of visual deception developed into an essential part of modern military tactics. In that war, long-range artillery and observation from the air combined to expand the field of fire, and camouflage was widely used to decrease the danger of being targeted or to enable surprise. As such, military camouflage is a form of military deception. Camouflage was first practiced in simple form in the mid 18th century by rifle units. Their tasks required them to be inconspicuous, and they were issued gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates 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 emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PT-91
The PT-91 Twardy (, en, Tough, link=no) is a Polish main battle tank. A development of the T-72M1, it entered service in 1995. The PT-91 was designed at the OBRUM (''Ośrodek Badawczo-Rozwojowy Urządzeń Mechanicznych'', or ''Research and Development Centre for Mechanical Appliances'') and is produced by the Bumar Łabędy company, part of the Bumar Group, a Polish technical military consortium. Changes from the T-72M include a new dual-axis stabilized fire-control system, reactive armour, a more powerful engine, transmission and new automatic loader. Unlike many other T-72 upgrades, Polish Army PT-91s feature elements created almost exclusively by domestic companies, including the new engine, fire control system, and all communication system elements. Many of the elements were used to upgrade existing fleets of T-72 tanks in countries including the Czech Republic ( T-72M4 CZ), Georgia (T-72SIM-1), and India (T-72 Ajeya Mk. 2). A total of 232 PT-91 tanks were delivered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopard 2
The Leopard 2 is a 3rd generation main battle tank originally developed by Krauss-Maffei in the 1970s for the West German army. The tank first entered service in 1979 and succeeded the earlier Leopard 1 as the main battle tank of the West German Army. It is armed with a 120 mm smoothbore cannon, and is powered by a V-12 twin-turbo diesel engine. Various versions have served in the armed forces of Germany and 13 other European countries, as well as several non-European nations, including Canada, Chile, Indonesia, and Singapore. The Leopard 2 was used in Kosovo with the German Army, in Afghanistan with the Dutch, Danish and Canadian contributions to the International Security Assistance Force, and saw action in Syria with the Turkish Armed Forces. There are two main development batches of the tank: the original models up to Leopard 2A4, which have vertically faced turret armour, and the improved batch, namely the Leopard 2A5 and newer versions, which have angled arrow-shape ...

KTO Rosomak
The KTO Rosomak (Kołowy Transporter Opancerzony Rosomak) (pol. wheeled armored personnel carrier Wolverine) is an 8×8 multi-role military vehicle produced by Rosomak S.A. (formerly Wojskowe Zakłady Mechaniczne) in Siemianowice Śląskie (Upper Silesia), a Polish Armaments Group company. The vehicle is a licensed variant of Patria's armored modular vehicle. History In December 2002, the Polish Ministry of National Defense signed a contract to buy 690 Patria AMV vehicles, to be manufactured in Poland. The main competitors of the AMV were the MOWAG Piranha and Steyr Pandur. As part of the initial order, 690 vehicles were to be delivered in two basic variants: 313 combat IFVs and 377 transport-special base vehicles. In October 2013 the order increased to 997 for delivery between 2014 and 2019. The name "Rosomak" (Polish for "Wolverine") was chosen following a contest organized by the '' Nowa Technika Wojskowa'' magazine. The Rosomak replaced the obsolete OT-64 SKOT APCs an ...

Operation Enduring Freedom
Operation Enduring Freedom (OEF) was the official name used synonymously by the U.S. government for both the War in Afghanistan (2001–2014) and the larger-scale Global War on Terrorism. On 7 October 2001, in response to the September 11 attacks, President George W. Bush announced that airstrikes targeting Al-Qaeda and the Taliban had begun in Afghanistan. Operation Enduring Freedom primarily refers to the War in Afghanistan, but it was also affiliated with counterterrorism operations in other countries, such as OEF-Philippines and OEF-Trans Sahara. After 13 years, on 28 December 2014, President Barack Obama announced the end of Operation Enduring Freedom in Afghanistan. Subsequent operations in Afghanistan by the United States' military forces, both non-combat and combat, occurred under the name Operation Freedom's Sentinel. Subordinate operations Operation Enduring Freedom most commonly referred to the U.S.-led combat mission in Afghanistan. The codename was also used ...

Camouflage Patterns
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
