Air Defense Anti-Tank System
The Oerlikon/Martin Marietta air defense anti-tank system (US designation MIM-146 ADATS) is a dual-purpose short range surface-to-air and anti-tank missile system based on the M113A2 vehicle. The ADATS missile is a laser-guided supersonic missile with a range of 10 kilometers (6.2 miles), with an electro-optical sensor with TV and forward looking infrared (FLIR). The carrying vehicle also has a search radar with an effective range of over 25 kilometers (16 miles). The first firing of an ADATS missile occurred in June 1981. Canada was the launch customer for the system with 36 units on the M113 chassis ordered for the Canadian Army in 1986. The system was further developed and produced at a new facility in Québec. The US Army also selected ADATS installed on the M2 Bradley chassis but by the time it was ready for service the ending of the Cold War led the US Army to cancel its orders, after Oerlikon invested over CHF 1 billion in the project. A small number of vehicles, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Nova Scotia International Tattoo
The Royal Nova Scotia International Tattoo is a show inspired by Military Tattoos given by military bands and display teams. It has taken place annually in the capital of Nova Scotia, Halifax since 1979. It is currently held in the Halifax Scotiabank Centre. Background The Royal Nova Scotia International Tattoo is unique among other Tattoos in the world in that it is more theatrical in nature with a mixture of both military and civilian performers. It takes place in the Scotiabank Centre arena, a venue that, to some degree, resembles a traditional theatre in the round. The show is heavily costumed and intensively rehearsed with technical staff, choreographers, assistant directors, wardrobe staff and designers as part of the production team, which also sets it apart from traditional Tattoos. A recurring theme of ''Bond of Friendship'' is woven into the Nova Scotia Tattoo each year that is intended to confirm and to build international relationships. Additional themes, usuall ...

Cold War
The Cold War was a period of global Geopolitics, geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which lasted from 1947 until the dissolution of the Soviet Union in 1991. The term ''Cold war (term), cold war'' is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and Nuclear arms race, nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, Economic sanctions, embargoes, and sports diplomacy. After the end of World War II in 1945, during which the US and USSR had been allies, the USSR installed satellite state, satellite governments in its occupied territories in Eastern Europe and N ...

M2 Bradley
The M2 Bradley, or Bradley IFV, is an American infantry fighting vehicle that is a member of the Bradley Fighting Vehicle family. It is manufactured by BAE Systems Land & Armaments (formerly United Defense) and entered service in 1981, with fielding beginning in 1983. The Bradley is designed for reconnaissance and to transport a nine-man rifle squad, providing them protection from small arms fire, while providing firepower to both suppress and eliminate most threats to friendly infantry. It is designed to be highly maneuverable and to be fast enough to keep up with heavy armor during an advance. The M2 holds a crew of three: a commander, a gunner, and a driver, and can carry six fully equipped soldiers as passengers. In the year 2000 the total cost of the program was US$5,664,100,000 for 1,602 units, giving an average unit cost of $3,166,000, equivalent to $5,841,000 in 2025. Design The Bradley IFV was developed largely in response to the amphibious Soviet BMP family of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US Army
The United States Army (USA) is the primary land service branch of the United States Department of Defense. It is designated as the Army of the United States in the United States Constitution.Article II, section 2, clause 1 of the United States Constitution (1789).See alsTitle 10, Subtitle B, Chapter 301, Section 3001 It operates under the authority, direction, and control of the United States secretary of defense. It is one of the six armed forces and one of the eight uniformed services of the United States. The Army is the most senior branch in order of precedence amongst the armed services. It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> Th ...

Québec
Quebec is Canada's largest province by area. Located in Central Canada, the province shares borders with the provinces of Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast and a coastal border with the territory of Nunavut. In the south, it shares a border with the United States. Between 1534 and 1763, what is now Quebec was the French colony of ''Canada'' and was the most developed colony in New France. Following the Seven Years' War, ''Canada'' became a British colony, first as the Province of Quebec (1763–1791), then Lower Canada (1791–1841), and lastly part of the Province of Canada (1841–1867) as a result of the Lower Canada Rebellion. It was confederated with Ontario, Nova Scotia, and New Brunswick in 1867. Until the early 1960s, the Catholic Church played a large role in the social and cultural institutions in Quebec. However, the Quiet Revolution of the 1960s to 1980s increased the role of the Government of Q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Army
The Canadian Army () is the command (military formation), command responsible for the operational readiness of the conventional ground forces of the Canadian Armed Forces. It maintains regular forces units at bases across Canada, and is also responsible for the Army Reserve, the largest component of the Primary Reserve. The army is headed by the Commander of the Canadian Army and Chief of the Army Staff, who is subordinate to the Chief of the Defence Staff (Canada), Chief of the Defence Staff. The army is also supported by 3,000 civilian employees from the public service. The army was formed in 1855, as the Canadian Militia#Active militias, Active Militia, in response to the threat of the United States to the Province of Canada after the British garrison left for the Crimean War. This militia was later subdivided into the Permanent Active Militia and the Non-Permanent Active Militia. Finally, in 1940, an order in council changed the name of the Active Militia to the Canadian Arm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M113
The M113 is a fully tracked armored personnel carrier (APC) that was developed and produced by the FMC Corporation. The M113 was sent to United States Army Europe in 1961 to replace the mechanized infantry's M59 APCs. The M113 was first used in combat in April 1962 after the United States provided the South Vietnamese army (ARVN) with heavy weaponry such as the M113, under the Military Assistance Command, Vietnam (MACV) program. Eventually, the M113 was the most widely used armored vehicle of the U.S. Army in the Vietnam War and was used to break through heavy thickets in the midst of the jungle to attack and overrun enemy positions. It was largely known as an "APC" or an "ACAV" ( armored cavalry assault vehicle) by the allied forces. The M113 was the first aluminum Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13.

Forward Looking Infrared
Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation. The sensors installed in forward-looking infrared cameras, as well as those of other thermal imaging cameras, use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create an image assembled for video output. They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect is 3 to 12 μm and differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm). Design Infrared light falls into two basic ranges: ''long-wave'' and ''medium-wave''. Long-wave infrared (LWIR) cameras, sometimes called "far-infrared", operate at 8 to 12 μm and can see heat sources, such as hot ...

Electro-optics
Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials. It is closely related to photonics, the branch of optics that involves the application of the generation of photons. It is not only concerned with the " electro–optic effect", since it deals with the interaction between the electromagnetic ( optical) and the electrical ( electronic) states of materials. Electro-optical devices The electro-optic effect is a change in the optical properties of an optically active material in response to changes in an electric field. This interaction usually results in a change in the birefringence Birefringence, also called double refraction, is the optical property of a material having a refractive index that depends on the polari ...

Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Guidance
Laser guidance directs a robotics system to a target position by means of a laser beam. The laser guidance of a robot is accomplished by projecting a laser light, image processing and communication to improve the accuracy of guidance. The key idea is to show goal positions to the robot by laser light projection instead of communicating them numerically. This intuitive interface simplifies directing the robot while the visual feedback improves the positioning accuracy and allows for implicit localization. The guidance system may serve also as a mediator for cooperative multiple robots. Examples of proof-of-concept experiments of directing a robot by a laser pointer are shown on video. Laser guidance spans areas of robotics, computer vision, user interface, video games, communication and smart home technologies. Commercial systems Samsung Electronics Co., Ltd. may have been using this technology in robotic vacuum cleaners since 2014. Google Inc. applied for a ...
