Airsoft
Airsoft is a team game in which participants eliminate opposing players by tagging them out of play with spherical plastic projectiles shot with mock air weapons(usually powered by an electronic motor) called airsoft guns. Although similar to paintball in concept and gameplay, airsoft pellets do not leave visible markings on their target and hits are not always apparent. Though the pellets leave bruises or welts on exposed skin (and so protective gear is recommended), the game relies heavily on an honor system in which players who have been hit are expected to call themselves out. The airsoft guns used are mostly magazine-fed, with some having manual/battery-powered spring- piston pump power plants similar to Nerf Blasters, or pneumatically powered by replaceable compressed gas (e.g. propane ("green gas"), 1,1,1,2-tetrafluoroethane or ) canisters. Many airsoft guns also have mounting platforms compatible with genuine firearm accessories, and most cosmetically res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airsoft Guns
Airsoft guns are replica toy guns used in airsoft sports. They are a special type of low-power smoothbore air guns designed to shoot non-metallic spherical projectiles (pb) often colloquially (but incorrectly) referred to as " BBs", which are typically made of (but not limited to) plastic or biodegradable resin materials. Airsoft gun powerplants are designed to have low muzzle energy ratings (generally less than 1.5 J, or 1.1 ft⋅lb) and the pellets have significantly less penetrative and stopping powers than conventional airguns, and are generally safe for competitive sporting and recreational purposes if proper protective gear is worn. Depending on the design mechanism for pellet propulsion, airsoft guns can be categorized into two groups: mechanical, which consists of a coil spring-loaded piston air pump that is either manually cocked (e.g. spring guns) or automatically cycled by a battery-powered electric motor gearbox (e.g. AEGs); and pneumatic, which operates ...

Airsoft Pellets
Airsoft pellets are spherical projectiles used by airsoft guns. Typically made of plastic, they usually measure around in diameter (though selective models use 8 mm), and weigh , with the most common weights being 0.12 g and 0.20 g, while 0.25 g, 0.28 g, 0.30 g and 0.40 g pellets are also commonplace. Though frequently referred to as "''BB''s" among airsoft users, these pellets are ''not'' the same as either of the 4.5 mm metal projectiles that BB guns fire, or the -sized birdshot from which the term "BB" originated. Variants Although the majority of pellets bought and used are simple spherical projectiles made of plastic, some of the following special varieties can be used to give a player an advantage, such as higher quality pellets. Biodegradable Biodegradable pellets are available, and are often required by outdoor fields where sweeping is not an option.

MilSim
MilSim, an abbreviation of military simulation, refers to live-acted simulation of armed conflict scenarios conducted by civilians for entertainment, sporting or nostalgic purposes. It has been described as both a form of "extreme sport" and as historical reenactment. MilSim includes activities that strive to provide an experience of combat, simulate battlefield missions, or replicate military service-style training. The training is simulated because participants engage in mock scenarios and do not actually engage in real conflicts or use real weaponry. There are several forms of MilSim: physical shooting sports (e.g. airsoft, paintball, or laser tag) with an emphasis on realism based on military scenarios and team tactics; historical reenactment of famous battles; stylistic imitations of a specific military era or focus, such as cosplaying; and military-themed e-sports (e.g. video games). Airsoft guns are used commonly in MilSim due to their cosmetic realism, satisfactory external ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paintball
Paintball is a competitive team shooting sport in which players eliminate opponents from play by hitting them with spherical dye-filled gelatin capsules called paintballs that break upon impact. Paintballs are usually shot using low-energy air weapons called paintball markers that are powered by compressed air or carbon dioxide and were originally designed for remotely marking trees and cattle. The game was invented in May 1981 in New Hampshire by Hayes Noel, a Wall Street stock trader, and Charles Gaines, an outdoorsman and writer. A debate arose between them about whether a city-dweller had the instinct to survive in the woods against a man who had spent his youth hunting, fishing, and building cabins. The two men chanced upon an advertisement for a paint gun in a farm catalogue and were inspired to use it to settle their argument with 10 other men all in individual competition, eventually creating the sport of paintball. The sport is played for recreation and is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honor System
An honor system or honesty system is a philosophical way of running a variety of endeavors based on trust, honor, and honesty. Something that operates under the rule of the "honor system" is usually something that does not have strictly enforced rules governing its principles. In British English, it would more often be called a "trust system" and should not be confused with the British honours system. The honor system is also a system granting freedom from customary surveillance (as to students or prisoners) with the understanding that those who are so freed will be bound by their honor to observe regulations (e.g. prison farms are operated under the ''honor system''), and will therefore not abuse the trust placed in them. A person engaged in an honor system has a strong negative concept of breaking or going against it. The negatives may include community shame, loss of status, loss of a personal sense of integrity and pride or in extreme situations, banishment from one's c ...

Live Action Role-playing
A live action role-playing game (LARP) is a form of role-playing game where the participants physically portray their characters.(Tychsen et al. 2006:255) "LARPs can be viewed as forming a distinct category of RPG because of two unique features: (a) The players physically embody their characters, and (b) the game takes place in a physical frame. Embodiment means that the physical actions of the player are regarded as those of the character. LARP participants may dress in the costume of their character and carry appropriate physical props (e.g., an 18th century militia LARP participant may wear a military uniform and carry a musket). Whereas in a RPG played by a group sitting around a table, players describe the actions of their characters (e.g., "I run to stand beside my friend"); in an equivalent situation in a LARP, a player would physically run to the appropriate point within the game space." The players pursue goals within a fictional setting represented by real-world enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Gun
An air gun or airgun is a gun that fires projectiles pneumatically with compressed air or other gases that are mechanically pressurized ''without'' involving any chemical reactions, in contrast to a firearm, which pressurizes gases ''chemically'' via oxidation of combustible propellants that generates propulsive energy by breaking molecular bonds. Air guns come in both long gun (air rifle) and handgun (air pistol) forms. Both types typically propel metallic projectiles that are either diabolo-shaped pellet (air gun), pellets or spherical round shot, shots called BB (ammunition), BBs, although in recent years Minié ball-shaped cylindro-conoidal bullet, cylindro-conoidal projectiles called slug (projectile), slugs are gaining more popularity. Certain types of air guns (usually air rifles) may also launch fin-stabilized projectile such as flechette, darts (e.g., tranquilizer guns) or hollow-shaft arrows (so-called "airbows"). The first air guns were developed as early as the 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1,1,1,2-tetrafluoroethane
1,1,1,2-Tetrafluoroethane (also known as norflurane ( INN), R-134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming potential (1,430, compared to R-12's GWP of 10,900). It has the formula CFCHF and a boiling point of −26.3 °C (−15.34 °F) at atmospheric pressure. R-134a cylinders are colored light blue. A phaseout and transition to HFO-1234yf and other refrigerants, with GWPs similar to CO2, began in 2012 within the automotive market. Uses 1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historical Reenactment
Historical reenactment (or re-enactment) is an educational or entertainment activity in which mainly amateur hobbyists and history enthusiasts dress in historic uniforms or costumes and follow a plan to recreate aspects of a historical event or period. This may be as narrow as a specific moment from a battle, such as the reenactment of Pickett's Charge presented during the Great Reunion of 1913, or as broad as an entire period, such as Regency reenactment. While historical reenactors are generally amateurs, some participants are members of armed forces or historians. The participants, called reenactors, often do research on the equipment, uniform, and other gear they will carry or use. Reenactors buy the apparel or items they need from specialty stores or make items themselves. Historical reenactments cover a wide span of history, from the Roman empire to the major world wars and the Korean War of the 20th century. History Activities related to "reenactment" have a long hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
