M7 Spider
The M7 Spider is a networked United States anti-personnel munitions system that provides a secure remote command and control capability of up to 1500 meters for a hand-emplaced munition field. The system was developed by Alliant Techsystems (ATK) with its joint venture partner Textron Systems as a part of the Non-Self-Destruct Alternative (NSD-A) program and is intended to replace the Matrix remote trigger system currently deployed in Iraq which works with pre-existing mines like the M18 Claymore. Day & Zimmermann and General Dynamics are prime subcontractors. Design The system is composed of Munition Control Units (MCUs), a Remote Control Station (RCS), and a repeater for extending communication range. Up to 63 MCUs can be configured for each RCS. Each MCU can attach up to six Miniature Grenade Launchers (MGL) each of which covers a sixty degree arc. The MCUs are hand emplaced after which the operator can optionally command to deploy six triplines to provide a sensing netwo ...

M18 Claymore
The Claymore mine is a directional anti-personnel mine developed for the United States Armed Forces. Its inventor, Norman MacLeod, named the mine after a large medieval Scottish sword. Unlike a conventional land mine, the Claymore is command-detonated and directional, meaning it is fired by remote-control and shoots a wide pattern of metal balls into the kill zone. The Claymore can also be victim-activated by booby-trapping it with a tripwire firing system for use in area denial operations. The Claymore fires steel balls out to about within a 60° arc in front of the device. It is used primarily in ambushes and as an anti-infiltration device against enemy infantry. It is also used against unarmored vehicles. Many countries have developed and used mines like the Claymore. Examples include former Soviet Union models MON-50, MON-90, MON-100, and MON-200, as well as MRUD (Serbia), MAPED F1 (France), and Mini MS-803 (South Africa).

Engineers Make The Choice 140708-A-HD608-053
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

US Dollar
The United States dollar (symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Denial Weapons
An area denial weapon is a defensive device used to prevent an adversary from occupying or traversing an area of land, sea or air. The specific method used does not have to be totally effective in preventing passage (and sometimes is not) as long as it is sufficient to severely restrict, slow down, or endanger the opponent. Some area denial weapons pose long-lasting risks to anyone entering the area, specifically to civilians, and thus are often controversial. An area denial weapon can be part of an anti-access/area denial (A2/AD) strategy. Historical methods Anti-cavalry In medieval warfare, sharp and sturdy stakes were buried at the bottom of long lines of ditches, pointed end up diagonally, in order to prevent cavalry charges in a given area. Even if the stakes were spotted, soldiers would be forced to dismount and effectively give up their advantage as cavalry as well as becoming easier targets. The correct layout of these extensive lines of ditches and the quality control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
