A weapon, arm, or armament is any device used with intent to inflict damage or harm to living beings, structures, or systems. Weapons are used to increase the efficacy and efficiency of activities such as crime, law enforcement, self-defense, and warfare. In a broader context, weapons may be construed to include anything used to gain a strategic, material or mental advantage over an adversary.
While just about any ordinary objects such as sticks, stones, cars, or pencils can be used as weapons, many are expressly designed for the purpose – ranging from simple implements such as clubs, swords and guns, and to complicated modern intercontinental ballistic missiles, biological and cyberweapons.
The use of objects as weapons has been observed among chimpanzees,[1] leading to speculation that early hominids first began to use weapons as early as five million years ago.[2] However, this can not be confirmed using physical evidence because wooden clubs, spears, and unshaped stones would not have left an unambiguous record. The earliest unambiguous weapons to be found are the Schöninger Speere: eight wooden throwing spears dated as being more than 300,000 years old.[3][4][5][6][7]
Ancient weapons were evolutionary improvements of late neolithic implements, but then significant improvements in materials and crafting techniques created a series of revolutions in military technology:
The development of metal tools, beginning with copper during the Copper Age (about 3,300 BC) and followed shortly by bronze led to the Bronze Age sword and similar weapons.
The first defensive structures and fortifications appeared in the Bronze Age,[8] indicating an increased need for security. Weapons designed to breach fortifications followed soon after, for example the battering ram was in use by 2500 BC.[8]
Although early Iron Age swords were not superior to their bronze predecessors, once iron-working developed, around 1200 BC in Sub-Saharan Africa,[9][10] iron began to be used widely in weapon production[11]
Domestication of the horse and widespread use of spoked wheels by ca. 2000 BC,[12] led to the light, horse-drawn chariot. The mobility provided by chariots were important during this era.[citation needed] Spoke-wheeled chariot usage peaked around 1300 BC and then declined, ceasing to be militarily relevant by the 4th century BC.[13]
Cavalry developed once horses were bred to support the weight of a man[citation needed]. The horse extended the range and increased the speed of attacks.
Ships built as weapons or warships such as the trireme were in use by the 7th century BC.[14] These ships were eventually replaced by larger ships by the 4th century BC.
European warfare during the middle ages was dominated by elite groups of knights supported by massed infantry (both in combat and ranged roles). They were involved in mobile combat and sieges which involved various siege weapons and tactics. Knights on horseback developed tactics for charging with lances providing an impact on the enemy formations and then drawing more practical weapons (such as swords) once they entered into the melee. Whereas infantry, in the age before structured formations, relied on cheap, sturdy weapons such as spears and billhooks in close combat and bows from a distance. As armies became more professional, their equipment was standardized and infantry transitioned to pikes. Pikes are normally seven to eight feet in length, in conjunction with smaller side-arms (short sword).
In Eastern and Middle Eastern warfare, similar tactics were developed independent of European influences.
The introduction of gunpowder from the Far East at the end of this period revolutionized warfare. Formations of musketeers, protected by pikemen came to dominate open battles, and the cannon replaced the trebuchet as the dominant siege weapon.
The European Renaissance marked the beginning of the implementation of firearms in western warfare. Guns and rockets were introduced to the battlefield.
Firearms are qualitatively different from earlier weapons because they release energy from combustible propellants such as gunpowder, rather than from a counter-weight or spring. This energy is released very rapidly and can be replicated without much effort by the user. Therefore even early firearms such as the arquebus were much more powerful than human-powered weapons. Firearms became increasingly important and effective during the 16th century to 19th century, with progressive improvements in ignition mechanisms followed by revolutionary changes in ammunition handling and propellant. During the U.S. Civil War various technologies including the machine gun and ironclad warship emerged that would be recognizable and useful military weapons today, particularly in limited conflicts. In the 19th century warship propulsion changed from sail power to fossil fuel-powered steam engines.
The age of edged weapons ended abruptly just before World War I with rifled artillery. Howitzers were able to destroy masonry fortresses and other fortifications. This single invention caused a Revolution in Military Affairs (RMA) and established tactics and doctrine that are still in use today. See Technology during World War I for a detailed discussion.
An important feature of industrial age warfare was technological escalation – innovations were rapidly matched through replication or countered by yet another innovation. The technological escalation during World War I (WW I) was profound, producing armed aircraft and tanks.
This continued in the inter-war period (between WW I and WW II) with continuous evolution of all weapon systems by all major industrial powers. Many modern military weapons, particularly ground-based ones, are relatively minor improvements of weapon systems developed during World War II. See military technology during World War II for a detailed discussion.
Since the mid-18th century North American French-Indian war through the beginning of the 20th century, human-powered weapons were reduced from the primary weaponry of the battlefield yielding to gunpowder-based weaponry. Sometimes referred to as the "Age of Rifles",[15] this period was characterized by the development of firearms for infantry and cannons for support, as well as the beginnings of mechanized weapons such as the machine gun, the tank and the wide introduction of aircraft into warfare, including naval warfare with the introduction of the aircraft carriers.
World War I marked the entry of fully industrialized warfare as well as weapons of mass destruction (e.g., chemical and biological weapons), and weapons were developed quickly to meet wartime needs. Above all, it promised to the military commanders the independence from the horse and the resurgence in maneuver warfare through extensive use of motor vehicles. The changes that these military technologies underwent before and during the Second World War were evolutionary, but defined the development for the rest of the century.
World War II however, perhaps marked the most frantic period of weapons development in the history of humanity. Massive numbers of new designs and concepts were fielded, and all existing technologies were improved between 1939 and 1945. The most powerful weapon invented during this period was the atomic bomb, however many more weapons influenced the world in different ways.
Since the realization of Mutually Assured Destruction (MAD), the nuclear option of all-out war is no longer considered a survivable scenario. During the Cold War in the years following World War II, both the United States and the Soviet Union engaged in a nuclear arms race. Each country and their allies continually attempted to out-develop each other in the field of nuclear armaments. Once the joint technological capabilities reached the point of being able to ensure the destruction of the entire planet (see nuclear holocaust) then a new tactic had to be developed. With this realization, armaments development funding shifted back to primarily sponsoring the development of conventional arms technologies for support of limited wars rather than nuclear war.[16]
The end of a weapon's lifecycle has been determined differently in different cultures, and throughout history. Likewise, the disposal methods of used or no longer used weapons have varied.
The US military used ocean dumping for unused weapons and bombs, including ordinary bombs, UXO, landmines and chemical weapons from at least 1919 until 1970. Weapons dumped in the Gulf of Mexico have washed up on the Florida coast. The oil drilling activity at the seafloor off the Texas-Louisiana coast increases chances of encountering these weapons.[17] Fishermen have brought weapons disposed of at the Massachusetts Bay Disposal Site to various towns in Massachusetts.[18]
The production, possession, trade and use of many weapons are controlled. This may be at a local or central government level, or international treaty.

무기(武器, 영어: weapon)는 인류가 군집 생활을 하면서 야생 동물로부터 신변을 보호하기 위한 수단으로 발명되었을 뿐만 아니라 삶을 꾸려가기 위한 수단인 사냥에 필요한 도구로 사용되었다. 세월이 흐름에 따라 군집생활의 영역이 넓어지고 인구의 수가 늘어나고 알지 못하는 부족들과의 교류와 갈등이 심화됨으로써 살상 도구로서 무기가 쓰이고 발명되었다.
무기는 또한 전시에 대비한다는 뜻에서 이를 효율적으로 사용하기 위한 방책으로 매우 일찍이 무기를 사용한 이른바 스포츠가 생겨났다. 무기를 사용한 스포츠는 오늘날에 살상과는 거리가 먼 정신집중 혹은 체력 단련을 목적으로 널리 인정을 받고 있다.
또한 흔히 무기는 공격 병기만을 가리키나, 방패나 갑주와 같은 방어 병기도 무기에 포함된다.
시대마다 18반에 들어가고 빠지는 병기가 있으므로 명확하게 구분하기는 어려우나, 대략 다음과 같다.
