Counter-sniper Tactics
Counter-sniper tactics have evolved in sniper warfare to reduce the effectiveness of snipers. Reducing the risk of damage During the stalking phase of their attack, a sniper will, if time allows, try to identify high-value targets, such as other snipers or Senior officers and NCOs. They will do this by closely observing the behavior of the people in front of them. The intention is to identify who is in charge and then prepare to fire at them. It naturally follows that leaders should attempt to blend into the background by avoiding anything that distinguishes them from the most junior soldiers and attracts the interest of a sniper. In order to reduce a sniper's ability to damage the chain of command, doctrine and equipment need to prevent any observable "leadership" behaviors and signs. Insignia, e.g. rank insignia, should be subdued (i.e. dark or black as opposed to bright colors), camouflage colors on battledress, battledress identical for all ranks, military servants and ran ...

Trajectory
A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The mass might be a projectile or a satellite. For example, it can be an orbit — the path of a planet, asteroid, or comet as it travels around a central mass. In control theory, a trajectory is a time-ordered set of states of a dynamical system (see e.g. Poincaré map). In discrete mathematics, a trajectory is a sequence (f^k(x))_ of values calculated by the iterated application of a mapping f to an element x of its source. Physics of trajectories A familiar example of a trajectory is the path of a projectile, such as a thrown ball or rock. In a significantly simplified model, the object moves only under the influence of a uniform gravitational force field. This can ...

Loophole (firearm)
A loophole is a protected small opening, which allows a firearm to be aimed and discharged, while providing cover and concealment for the rifleman. To prevent detection, the rifle's muzzle should not protrude through the loophole, particularly at night to hide the muzzle flash. Arrowslit The precursor to the loophole for firearms was the arrowslit, which is a narrow aperture in a fortification for an archer to launch arrows or an arbalist to launch crossbow bolts. The earliest use of the arrowslit was alleged to have been by Archimedes during the siege of Syracuse in 214–212 BC. Arrowslits were used in ancient Greek warfare and by the military of ancient Rome. There was a reintroduction of arrowslits during the medieval warfare period at Dover Castle and Framlingham Castle in England and by Richard the Lionheart at Château Gaillard in France.

Smoke Grenade
A smoke grenade is a canister-type grenade used as a signaling device, target or landing zone marking device, or as a screening device for unit movements. Smoke grenades are generally more complex and emit a far larger amount of smoke than smoke bombs, which are a type of firework typically started with an external fuse rather than a pin. Smoke grenades often cost around compared to smoke bombs, which can often cost just a few cents. The phrase "to smoke", meaning to fake, bluff, or beat around the bush, comes from the military usage of smoke grenades to obscure and conceal movement; similarly, "pop smoke", derived from a common way of ordering the use of smoke grenades, is used as a slang term for quickly leaving a place. __TOC__ Design left, Diagram and cross section of an M18 smoke grenade A typical design consists of a sheet steel cylinder with four emission holes on top and one on the bottom to allow smoke release when the grenade is ignited. The filler consists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pincer Movement
The pincer movement, or double envelopment, is a maneuver warfare, military maneuver in which forces simultaneously attack both flanking maneuver, flanks (sides) of an enemy Military organization, formation. This classic maneuver has been important throughout the history of warfare. The pincer movement typically occurs when opposing forces advance towards the center of an army that responds by moving its outside forces to the enemy's flanks to surround it. At the same time, a second layer of pincers may attack the more distant flanks to keep reinforcements from the target units. Description A full pincer movement leads to the attacking army facing the enemy in front, on both flanks, and in the rear. If attacking pincers link up in the enemy's rear, the enemy is encirclement, encircled. Such battles often end in surrender or destruction of the enemy force, but the encircled force can try to breakout (military), break out. They can attack the encirclement from the inside to ...

Smoke Screen
A smoke screen is smoke released to mask the movement or location of military units such as infantry, tanks, aircraft, or ships. Smoke screens are commonly deployed either by a canister (such as a grenade) or generated by a vehicle (such as a tank or a warship). Whereas smoke screens were originally used to hide movement from enemies' line of sight, modern technology means that they are now also available in new forms; they can screen in the infrared as well as visible spectrum of light to prevent detection by infrared sensors or viewers, and they are also available for vehicles in a super-dense form used to block laser beams of enemy laser designators or rangefinders. Technology Smoke grenades These are canister-type grenades used as a ground-to-ground or ground-to-air signalling device. The body consists of a steel sheet metal cylinder with a few emission holes on the top and/or bottom to allow smoke release when the smoke composition inside the grenade is ignited. In ...

Fire Support
Fire support is a military tactics term used to describe weapons fire used to support friendly forces by engaging, suppressing, or destroying enemy forces, facilities, or materiel in combat. It is often provided through indirect fire, though the term may also be used for some forms of supporting direct fire. The United States Department of Defense defines fire support as " fires that directly support land, maritime, amphibious, and special operations forces to engage enemy forces, combat formations, and facilities in pursuit of tactical and operational objectives." Overview Fire support generally consists of fire from heavy or crew-served weaponry with high firepower, including strikes and barrages from artillery, mortars, rocket artillery, and missiles; naval gunfire support from naval artillery; airstrikes, strafes, and close air support from military aircraft; and drone strikes from unmanned combat aerial vehicles; among various other forms.

PackBot
PackBot is a series of military robots by Endeavor Robotics (previously by iRobot), an international robotics company founded in 2016, created from iRobot, that previously produced military robots since 1990. More than 2000 were used in Iraq and Afghanistan. They were also used to aid searching through the debris of the World Trade Center (1973–2001), World Trade Center after September 11 attacks, 9/11 in 2001. Another instance of the PackBot technology being implemented was to the damaged Fukushima Daiichi nuclear disaster, Fukushima nuclear plant after the 2011 Tōhoku earthquake and tsunami where they were the first to assess the site. As of November 2014, the U.S. Army is refurbishing 224 iRobot 510 robots. The PackBot technology is also used in collaboration with NASA for their rovers and probes.

Defense Advanced Research Projects Agency
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996. ''The Economist'' has called DARPA "the agency that shaped the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boomerang (mobile Shooter Detection System)
Boomerang is a gunfire locator developed by DARPA and BBN Technologies primarily for use against snipers. Boomerang is mounted on mobile vehicles such as the Humvee, Stryker, and MRAP combat vehicles. There were plans to integrate it into the Land Warrior system. Development Boomerang grew out of a program conceived by the U.S. Department of Defense in late 2003, months after the traditional combat phase of the Iraq War had ended on 1 May, at a time when it was clear that U.S. troops were increasingly at risk from a growing and aggressive insurgency. Often, troops in noisy Humvees did not know they were being shot at until someone was hit. U.S. Defense Secretary Donald Rumsfeld approached DARPA and asked for near-term solutions that could be applied to the conflict in Iraq. Rumsfeld was looking for something that did not have to be a perfect solution, but was at least better than nothing. The U.S. Army and Special Operations Command began using a limited number of French-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonic Boom
A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear. The crack of a supersonic bullet passing overhead or the crack of a bullwhip are examples of a small sonic boom. Sonic booms due to large supersonic aircraft can be particularly loud and startling, tend to awaken people, and may cause minor damage to some structures. This led to the prohibition of routine supersonic flight overland. Although sonic booms cannot be completely prevented, research suggests that with careful shaping of the vehicle, the nuisance due to sonic booms may be reduced to the point that overland supersonic flight may become a feasible option. A sonic boom does not occur only at the moment an object crosses the sound barrier and neither is it heard in all directions emanating from the supersonic objec ...
