A weapon, arm, or armament is any implement or device that is used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In a broader context, weapons may be construed to include anything used to gain a tactical, strategic, material, or mental advantage over an adversary or enemy target.
The nunchaku, "nunchucks", "chainsticks", or "chuka sticks" in English) is a traditional East-Asian martial arts weapon consisting of two sticks, connected to each other at their ends by a short metal chain or a rope. It is approximately 30 cm or 12 inches (sticks) and 2.5 cm or 1 inch (rope). A person who has practiced using this weapon is referred to in Japanese as nunchakuka.
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports.
Non-lethal weapons, also called nonlethal weapons, less-lethal weapons, less-than-lethal weapons, non-deadly weapons, compliance weapons, or pain-inducing weapons are weapons intended to be less likely to kill a living target than conventional weapons such as knives and firearms with live ammunition. It is often understood that unintended or incidental casualties are risked wherever force is applied, however non-lethal weapons minimise the risk of casualties as much as possible. Non-lethal weapons are used in policing and combat situations to limit the escalation of conflict where employment of lethal force is prohibited or undesirable, where rules of engagement require minimum casualties, or where policy restricts the use of conventional force. However, these weapons occasionally cause serious injuries or death due to allergic reactions, improper use and/or other factors; for this reason the term "less-lethal" has been preferred by some organizations as it describes the risks of death more accurately than the term "non-lethal", which some have argued is a misnomer.
Riot control measures are used by law enforcement, military, paramilitary or security forces to control, disperse, and arrest people who are involved in a riot, unlawful demonstration or unlawful protest.
An injury is any physiological damage to living tissue caused by immediate physical stress. Injuries to humans can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries.
A club is a short staff or stick, usually made of wood, wielded as a weapon or tool since prehistory. There are several examples of blunt-force trauma caused by clubs in the past, including at the site of Nataruk in Turkana, Kenya, described as the scene of a prehistoric conflict between bands of hunter-gatherers 10,000 years ago.
The ARWEN 37 is a less-lethal launcher which fires a variety of 37mm less-lethal munitions which includes direct impact batons, chemical irritant delivery munitions and smoke delivery munitions. The ARWEN 37 has 5-round rotary drum magazine.
A penetrating head injury, or open head injury, is a head injury in which the dura mater, the outer layer of the meninges, is breached. Penetrating injury can be caused by high-velocity projectiles or objects of lower velocity such as knives, or bone fragments from a skull fracture that are driven into the brain. Head injuries caused by penetrating trauma are serious medical emergencies and may cause permanent disability or death.
The ARWEN ACE is a breech-loaded less-lethal launcher which fires a variety of 37mm less-lethal munitions which includes direct impact batons, chemical irritant delivery munitions and smoke delivery munitions.
A deadly weapon, sometimes dangerous weapon or lethal weapon, is an item that can inflict mortal or great bodily harm. By statutory definition, certain items, especially firearms, are designated "deadly weapons per se", meaning they are regarded as deadly weapons no matter how they are used, from the Latin for "by itself". In addition, deadly weapons statutes often contain provisions covering other implements intended to be used to inflict harm.
Physical or chemical injuries of the eye can be a serious threat to vision if not treated appropriately and in a timely fashion. The most obvious presentation of ocular (eye) injuries is redness and pain of the affected eyes. This is not, however, universally true, as tiny metallic projectiles may cause neither symptom. Tiny metallic projectiles should be suspected when a patient reports metal on metal contact, such as with hammering a metal surface. Corneal foreign bodies are one of the most common preventable occupational hazards. Intraocular foreign bodies do not cause pain because of the lack of nerve endings in the vitreous humour and retina that can transmit pain sensations. As such, general or emergency department doctors should refer cases involving the posterior segment of the eye or intraocular foreign bodies to an ophthalmologist. Ideally, ointment would not be used when referring to an ophthalmologist, since it diminishes the ability to carry out a thorough eye examination.
Stopping power is the ability of a weapon – typically a ranged weapon such as a firearm – to cause a target to be incapacitated or immobilized. Stopping power contrasts with lethality in that it pertains only to a weapon's ability to make the target cease action, regardless of whether or not death ultimately occurs. Which ammunition cartridges have the greatest stopping power is a much-debated topic.
In martial arts, a waster is a practice weapon, usually a sword, and usually made out of wood, though nylon (plastic) wasters are also available. Nylon is safer than wood, due to it having an adequate amount of flex for thrusts to be generally safe, unlike wooden wasters. Even a steel feder has more flex than most wooden wasters. The use of wood or nylon instead of metal provides an economic option for initial weapons training and sparring, at some loss of genuine experience. A weighted waster may be used for a sort of strength training, theoretically making the movements of using an actual sword comparatively easier and quicker, though modern sports science shows that an athlete would most optimally train with an implement which is closest to the same weight, balance, and shape of the tool they will be using. Wasters as wooden practice weapons have been found in a variety of cultures over a number of centuries, including ancient China, Ireland, Iran, Scotland, Rome, Egypt, medieval and renaissance Europe, Japan, and into the modern era in Europe and the United States. Over the course of time, wasters took a variety of forms not necessarily influenced by chronological succession, ranging from simple sticks to clip-point dowels with leather basket hilts to careful replicas of real swords.
Blunt trauma, also known as blunt force trauma or non-penetrating trauma, describes a physical trauma due to a forceful impact without penetration of the body's surface. Blunt trauma stands in contrast with penetrating trauma, which occurs when an object pierces the skin, enters body tissue, and creates an open wound. Blunt trauma occurs due to direct physical trauma or impactful force to a body part. Such incidents often occur with road traffic collisions, assaults, and sports-related injuries, and are notably common among the elderly who experience falls.
A sponge grenade is a riot control weapon, intended to be non-lethal, which is fired from a 40 mm grenade launcher to cause confusion, or otherwise temporarily disable its target. As a single blunt force object, it is best used when aimed at a particular individual.
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment. The penetrating object may remain in the tissues, come back out the path it entered, or pass through the full thickness of the tissues and exit from another area.
A baton is a roughly cylindrical club made of wood, rubber, plastic, or metal. It is carried as a compliance tool and defensive weapon by law-enforcement officers, correctional staff, security guards and military personnel. The name baton comes from the French bâton (stick), derived from Old French Baston, from Latin bastum.
Weighted-knuckle gloves, also called sap gloves, are a type of handwear-concealed melee weapon used in hand-to-hand combat, consisting of a pair of ordinary-looking impact protection gloves usually made of leather or a synthetic material, with powdered lead or steel sewn into a special pouch covering the knuckles, and often also the backs of the fingers and the hand. In some designs, this distinctive feature is obvious, while in others it is almost completely indistinguishable from an ordinary glove, allowing the gloves to be worn in plain sight without suspicion.
A liver injury, also known as liver laceration, is some form of trauma sustained to the liver. This can occur through either a blunt force such as a car accident, or a penetrating foreign object such as a knife. Liver injuries constitute 5% of all traumas, making it the most common abdominal injury. Generally nonoperative management and observation is all that is required for a full recovery.
