Mass murder is the act of killing a number of people, typically simultaneously or over a relatively short period of time and in proximity. A mass murder typically occurs in a single location where one or more persons kill several others.
Tunnel vision is the loss of peripheral vision with retention of central vision, resulting in a constricted circular tunnel-like field of vision.
Iron sights are a system of physical alignment markers used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearms, airguns, crossbows, and bows, or less commonly as a primitive finder sight for optical telescopes. Iron sights are the earliest type of sighting device, as it relies completely on the viewer's naked eye, and is distinctly different to optical sights such as telescopic sights, reflector sights, holographic sights, and laser sights, which make use of optical manipulation and/or active illumination.
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a reticle – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. Similar devices are also found on other platforms such as artillery, tanks and even aircraft. The optical components may be combined with optoelectronics to add night vision or smart device features.
A shooting range, firing range, gun range or shooting ground is a specialized facility, venue, or field designed specifically for firearm usage qualifications, training, practice, or competitions. Some shooting ranges are operated by military or law enforcement agencies, though the majority of ranges are privately owned by civilians and sporting clubs and cater mostly to recreational shooters. Each facility is typically overseen by one or more supervisory personnel, known as a Range Officer (RO), or sometimes a range master in the United States. Supervisory personnel are responsible for ensuring that all safety rules and relevant laws are followed at all times.
Point shooting is a practical shooting method where the shooter points a ranged weapon at a target without relying on the use of sights to aim. Emphasis is placed on fast draw and trying to score preemptive hits first. In close quarters combat, where life-threatening situations emerge very quickly, sighted marksmanship techniques become risky, so advocates of point shooting emphasize a less sighting-oriented style that prioritizes the tactical advantages of quick fire superiority and suppression.
Target fixation is an attentional phenomenon observed in humans in which an individual becomes so focused on an observed object that they inadvertently increase their risk of colliding with the object. It is associated with scenarios in which the operator is in control of a high-speed vehicle or other mode of transportation, such as fighter pilots, race-car drivers, paragliders, and motorcyclists. In such cases, the observer may fixate so intently on the target that they steer in the direction of their gaze, which is often the ultimate cause of a collision. The term target fixation was originally used in World War II fighter-bomber pilot training to describe pilots flying into targets during a strafing or bombing run.
Coquihalla Canyon Provincial Park, popularly called the Othello Tunnels is a provincial park located near Hope, British Columbia focused on the canyon of the Coquihalla River and a decommissioned railway grade, now a walking trail, leading eventually to Coquihalla Pass. Originally part of the Kettle Valley Railway, five tunnels and a series of bridges follow a relatively straight line through the gorge, which is lined with sheer, flat rock cliffs.
The Getaway: High Speed II is a 1992 pinball game by Steve Ritchie. It is a sequel to 1986's High Speed.
A globe sight is a front sight component used to assist the aiming of a gun/device, usually those intended to launch projectiles, such as firearms, airguns, and crossbows. It is found in particular as a front sight element on rifles.
A diopter sight is an aperture sight component used to assist the aiming of ranged weapons, mainly firearms, airguns, and crossbows. Diopters function to precisely align the shooter's eye with the front sight and the target, while also producing beneficial optical effects for accurate aiming. A diopter must be paired with a complementing front sight element to obtain a usable sighting line. Diopter sights used for modern target shooting allow for very fine windage and elevation adjustments, moving the impact point on the order of less than five millimeters at a range of 100 metres. High end diopters typically accept accessories to aid the shooter's ability to see the target clearly.
A red dot sight is a common classification for a non-magnifying reflector sight that provides an illuminated red dot to the user as a point of aim. A standard design uses a red light-emitting diode (LED) at the focus of collimating optics, which generates a dot-style illuminated reticle that stays in alignment with the firearm the sight is attached to, regardless of eye position.
Strafing in video games involves sliding in one direction allowing the player to the arrive at their intended destination while increasing speed. It also allows a player to move in one direction while keeping the camera focused on a target in a different direction.
Tunnel vision is the loss of peripheral vision
The Radiological Research Accelerator Facility (RARAF), located on the Columbia University Nevis Laboratories campus in Irvington, New York is a National Institute of Biomedical Imaging and Bioengineering biotechnology resource center (P41) specializing in microbeam technology. The facility is currently built around a 5MV Singletron, a particle accelerator similar to a Van de Graaff.
The Cobra is a 2010 thriller novel by British writer Frederick Forsyth, about the international cocaine trade. In it, an unnamed Obama-like U.S. President colludes with an unnamed Cameron-like British Prime Minister to put an end to the international cocaine trade and brings in ex-CIA Director Paul Devereaux who is basically given carte blanche to accomplish this task by any means necessary. The book re-introduces some of the characters from Forsyth's book Avenger.
Tatler is a British magazine published by Condé Nast Publications. It focuses on fashion and lifestyle, as well as coverage of high society and politics. Targeted towards the British and global upper class and upper-middle class, as well as those interested in society events, its readership is the wealthiest of all Condé Nast's publications.
The shootings at the pub Vår Krog & Bar in Gothenburg happened on 18 March 2015. Two unidentified gunmen entered a pub in Gothenburg, Sweden and began firing indiscriminately at people inside the restaurant. The pub, Vår Krog & Bar, is located in the Biskopsgården neighbourhood of Gothenburg on Hisingen, an area that has witnessed gang violence. The shootings are one of the rare times in which an innocent bystander has been killed in criminal rival gang violence in Sweden. The shooters were part of a gang from North Biskopsgården out for revenge.
Shooting glasses are specialized corrective glasses for use in shooting and are used almost exclusively in sport shooting competitions. Like other glasses, they are worn in front of the eyes to compensate for the shooter's ametropia with optical lenses.
"Tunnel Vision (Outro)" is a drill song by American rapper Pop Smoke from his posthumous debut studio album, Shoot for the Stars, Aim for the Moon (2020). The song was written by Pop Smoke, known as Bashar Jackson, alongside 808Melo, who has the real name of Andre Loblack, Jugraj Nagra, and Carson Hackney. It was produced by the latter three. The original melody of the song is called "Wild West" and had a Western flute over it. In the lyrics, Pop Smoke raps about looking towards his future and wanting to have an impact on the music industry.
