Black operation

A black operation or black op is a covert operation by a government, a government agency, or a military organization. This can include activities by private companies or groups. Key features of a black operation are that it is secret and it is not attributable to the organization carrying it out. The main difference between a black operation and one that is merely secret is that a black operation involves a significant degree of deception, to conceal who is behind it or to make it appear that some other entity is responsible ("false flag" operations).

A single such activity may be called a "black bag operation"; that term is primarily used for covert or clandestine surreptitious entries into structures to obtain information for human intelligence operations. Such operations are known to have been carried out by the FBI, the Central Intelligence Agency,Mossad, MI6, ISI (Pakistan), RAW, MSS, and the intelligence services of other nations.

Etymology

"Black" may be used as a generic term for any government activity that is hidden or secret. For example, some activities by military and intel agencies are funded by a classified "black budget," of which the details, and sometimes even the total, are hidden from the public and from most congressional oversight.

Setting and characters

Call of Duty: Black Ops III takes place in 2065, 40 years after the events of Black Ops II, in a world facing upheaval from climate change and new technologies. In response to the drone assaults of Black Ops 2, several countries around the world have developed high-tech air defenses that render conventional air forces virtually useless. As such, most of the warfare between countries is done by covert operatives fighting behind enemy lines. Military technology has progressed to the point where robotics play a major role in combat, and both fully robotic humanoid drones and cyborg supersoldiers have been developed to fight in the battlefield. As a result, there is speculation and fear about an eventual robotic takeover. The game follows a team of black ops soldiers, like previous installments in the Black Ops series.

Call of Duty

Call of Duty is a first-person shooter video game franchise. The series began on Microsoft Windows, and later expanded to consoles and handhelds. Several spin-off games have been released. The earlier games in the series are set primarily in World War II, including Call of Duty, Call of Duty 2, and Call of Duty 3. Beginning with Call of Duty 4: Modern Warfare, which is set in modern times, the series has shifted focus away from World War II. Modern Warfare, released November 2007, was followed by World at War and Modern Warfare 2. Black Ops, released November 2010, takes place in the Cold War, while Modern Warfare 3, released November 2011, takes place in a near-future setting. Black Ops II, released November 2012, takes place mainly in the year 2025. Call of Duty: Ghosts was released in November 2013. In May 2014, Advanced Warfare was announced. On April 9, 2015, Treyarch announced Black Ops III.

The Call of Duty games are published and owned by Activision. While Infinity Ward is still a developer, Treyarch and Sledgehammer Games also develop several of the titles with the release of the studios' games alternating with each other. Some games have been developed by Gray Matter Interactive, Nokia, Exakt Entertainment, Spark Unlimited, Amaze Entertainment, n-Space, Aspyr, Rebellion Developments, Ideaworks Game Studio, and nStigate Games. The games use a variety of engines, including the id Tech 3, the Treyarch NGL, and the IW engine.

XR-2

The XR-2 is an educational robot made by Rhino Robotics.

The robot is a multi-jointed arm, having five degrees of freedom. (Not six, unless it is attached to the optional sliding base.) The arm is constructed of aluminum and the workings of the robot, such as geared electric motors and their rotary encoders, are visible.

A controller, based on the 6502 CPU also found in the robot's contemporary, the Apple II, can control up to eight motors - the robot and two other items, such as a turntable or the aforementioned sliding base.

There is a teach pendant, rather like those of full-size industrial robots, that can be connected to the controller. Using this, the robot can be "taught" simple programs using the pendant and can then repeat them.

Controller interface

The interface for the motor controller is based on a RS-232 serial port. (9600 baud, 7 data bits, 2 stop bits, even parity.) The controller, while in one physical box, is actually two machines. The one on the top is the teach pendant computer, the one below is the motor controller proper.

Black

Black is the darkest color, the result of the absence of or complete absorption of light. It is the opposite of white (the combined spectrum of color or light). It is an achromatic color, literally a color without color or hue. It is one of the four primary colors in the CMYK color model, along with cyan, yellow, and magenta, used in color printing to produce all the other colors.

Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century.

In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches and magic. According to surveys in Europe and North America, it is the color most commonly associated with mourning, the end, secrets, magic, force, violence, evil, and elegance.
