Throwing Weapons
Throwing is a physical action that consists of mechanics, mechanically acceleration, accelerating a projectile and then releasing it into a ballistics, ballistic trajectory, usually with the aim of impact (mechanics), impacting a distant target. ''Throwing'' typically refers to hand-throwing by animals with prehensile forelimbs, in which the projectile is grasping, grasped in a hand and the proximal limb segments move through compounded kinematic chains to impart a mechanical advantage, mechanically advantaged swinging motion. For other animals, the definition of throwing is somewhat unclear, as other actions such as spitting or spray (liquid drop), spraying may or may not be included. Primates are the most proliferative throwers in the animal kingdom, and they typically throw feces as a form of agonistic behavior. Of all primates, Homo, humans are by far the most capable throwers, and throw a large variety of projectiles with a much greater complexity, efficacy and accuracy. T ...

Feces
Feces (also known as faeces American and British English spelling differences#ae and oe, or fæces; : faex) are the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine. Feces contain a relatively small amount of metabolic waste products such as bacterially-altered bilirubin and dead epithelial cells from the lining of the gut. Feces are discharged through the anus or cloaca during defecation. Feces can be used as fertilizer or soil conditioner in agriculture. They can also be burned as dry animal dung fuel, fuel or dried and used for wattle and daub, construction. Some medicinal uses have been found. In the case of human feces, fecal transplants or fecal bacteriotherapy are in use. Urine and feces together are called excretion, excreta. Characteristics The distinctive odor of feces is due to skatole, and thiols (sulfur-containing compounds), as well as amines and carboxylic acids. Sk ...

Tear Gas
Tear gas, also known as a lachrymatory agent or lachrymator (), sometimes colloquially known as "mace" after the Mace (spray), early commercial self-defense spray, is a chemical weapon that stimulates the nerves of the lacrimal gland in the eye to produce tears. In addition, it can cause severe eye and respiratory pain, skin irritation, bleeding, and blindness. Common lachrymators both currently and formerly used as tear gas include pepper spray (OC gas), PAVA spray (nonivamide), CS gas, CR gas, CN gas (phenacyl chloride), bromoacetone, xylyl bromide, chloropicrin (PS gas) and Mace (spray), Mace (a branded mixture). While lachrymatory agents are commonly deployed for riot control by law enforcement and military personnel, its use in warfare is prohibited by various international treaties.E.g. the Geneva Protocol of 1925 prohibited the use of "asphyxiating gas, or any other kind of gas, liquids, substances or similar materials". During World War I, increasingly toxic and deadly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stun Grenade
A stun grenade, also known as a flash grenade, flashbang, thunderflash, or sound bomb, is a Non-lethal weapon, non-lethal explosive device used to temporarily disorient an enemy's senses. Upon detonation, a stun grenade produces Flash blindness, a blinding flash of light and an extremely loud "bang". They are often used in close-quarters combat, door breaching, and riot control, typically to stun enemies or distract them. Originally developed to simulate explosions during military training, stun grenades were first used by the British Army Special Air Service's Counterterrorism, counterterrorist wing in the late 1970s, and have been used by police and military forces worldwide since. Despite their less-lethal nature, stun grenades are still capable of causing harm, and can injure or kill when detonating in close proximity. They are also capable of sparking fires. Effects Stun grenades are designed to produce a blinding flash of light of around 7 megacandela (Mcd) and an intens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Grenade
A grenade is a small explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a Shell (projectile), shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal Firing pin, striker to trigger the detonator, an arming safety secured by a transport safety. The user removes the transport safety before throwing, and once the grenade leaves the hand the arming safety gets released, allowing the striker to trigger a Percussion cap, primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (High explosive, high-explosive, Anti-tank grenade, anti-tank and stun grenades), chemical aerosols (Smoke grenade, smoke, Grenade#Chemical and gas, gas and Grenade#Chemi ...

Dart (missile)
Darts are airborne ranged weapons. They are designed to fly such that a sharp, often weighted point will strike first. They can be distinguished from javelins by the presence of fletching (feathers on the tail) and a shaft that is shorter or more flexible. Darts can be propelled by hand or with the aid of a hand-held implement such as a blowgun. They can be distinguished from arrows because they are not used with a Bow and arrow, bow. Darts have been used since pre-history. The plumbatae were lead-weighted darts thrown by infantrymen in Antiquity and the Middle Ages. Darts can be propelled by a number of means. The atlatl uses leverage to increase the velocity of the dart, the kestros (weapon), kestros increases the range of propelled darts using a sling, and the exhalation of a person's breath through a blowgun propels small stone points or poisoned needles with pneumatic force. In the modern era, darts have been used for recreation in lawn darts and the game of darts. Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Throwing Axe
A throwing axe is a weapon used from Antiquity to the Middle Ages by foot soldiers and occasionally by mounted soldiers. Usually, they are thrown in an overhand motion in a manner that causes the axe to rotate as it travels through the air. Axe throwing is a sport in which the competitor throws an axe at a target, attempting to hit the bullseye as near as possible like that of the archery. Axe throwing is an event held in most lumberjack competitions. A skilled axe thrower will rotate the throwing axe exactly once throughout the flight so that the sharpened edge of the head will penetrate the target. Throwing axes are becoming popular among outdoor enthusiasts as a throwing tool. Francisca The francisca is a throwing axe associated with the Franks in the 3rd century CE. Its design was also used by other Germanic peoples of the period including the Anglo-Saxons. The francisca is characterised by its distinctly arch-shaped head, widening toward the cutting edge and terminati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spear
A spear is a polearm consisting of a shaft, usually of wood, with a pointed head. The head may be simply the sharpened end of the shaft itself, as is the case with Fire hardening, fire hardened spears, or it may be made of a more durable material fastened to the shaft, such as bone, flint, obsidian, copper, bronze, iron, or steel. The most common design for hunting and/or warfare, since modern times has incorporated a metal spearhead shaped like a triangle, lozenge (shape), diamond, or Glossary of leaf morphology, leaf. The heads of fishing spears usually feature multiple sharp Tine (structural), points, with or without barbs. Spears can be divided into two broad categories: those designed for thrusting as a melee weapon (including weapons such as lances and Pike (weapon), pikes) and those designed for throwing as a ranged weapon (usually referred to as javelins). The spear has been used throughout human history as a weapon for hunting and/or fishing and for warfare. Along with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Throwing
Stone throwing or rock throwing, when it is directed at another person (called stone pelting in India), is often considered a form of criminal battery. In certain political contexts, stone-throwing is considered a form of civil resistance. History The throwing of rocks or stones is one of the most ancient forms of ranged-weapon combat, with stone-throwing slings found among other weapons in the tomb of Tutankhamen, who died about 1325 BC. Xenophon mentions the petrobóloi () in his work '' Hellenica'', and Thucydides and Cassius Dio both mention the lithobóloi () in ''History of the Peloponnesian War'' and ''Histories'' respectively. Both terms mean stone-throwers in Ancient Greek, as army units. De re militari (Latin "Concerning Military Matters") by the Roman writer Publius Flavius Vegetius Renatus details Roman soldiers training to throw stones as weapons. "Recruits are to be taught the art of throwing stones both with the hand and sling." And "Formerly all soldier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hunting
Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species (commonly called a culling#Wildlife, cull). Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a ...
