1 Introduction after the end of the cold war, peace and development have become the theme of the times. Small the possibility of large-scale war, army, police to participate in "the maintenance of peace" and "non-war actions" growing at the same time, calls for peace in the world, call for humane voices rising, the practice of relying on mass destruction and failure to win will be strongly condemned, but to weaken or under the control of the enemy's fighting power of non-lethal weapons increasingly obvious. Non-lethal weapons, also known as non-lethal weapons, weak anti-personnel weapons, deactivation of weapons, mainly refers to the use of acoustic, optical, electromagnetic, chemical means such as enemy officers or the combat capability of weapon equipment loss or reduced, but does not cause a large number of casualties and weapon equipment badly damaged new weapons, and by reason of its "non-lethal, is billed as the" inhumane weapons ". The US military believes that non-lethal weapons can reduce loss of life, enable us to win support at home and abroad, subject to guarantees for the ultimate purpose of the US military. Since the 90 's, especially after the Gulf war, the developed countries were committed to the development of non-lethal technology, in the context of a new round of high technology race. Non-lethal weapons after more than 10 years of development, both in theory and in practice has made great progress, 21st century is a century of rapid development of deadly weapons, actively carry out famous weapons research was undoubtedly profound. Military experts predict that the "non-lethal weapons have the potential to dramatically change the nature of the war, the fundamental change in the future operations of the war. "Non-lethal weapon2 2.1 background and present situation of development of non-lethal weapons development background trace the real rise of non-lethal weapons, had to go back to 1995. At that time, to protect the last of the safety of United Nations peacekeeping personnel evacuated out of Somalia, the United Nations carried out a "United Shield" action to avoid an escalation of conflict, peacekeepers used non-lethal weapons. The whole operation period, no casualties of United Nations peacekeeping forces. Since then, defense based on the experience in Somalia began to expand the joint non-lethal weapon project, also followed in other countries, intensive research and development in the field of special use of such new weapons. In 1997, entrusted by the Congress, United States Department of Defense established the joint non-lethal weapon project, United States Marine Corps as the executing agency and is responsible for leadership, whose mission is to "support, discovery, research, development, test and assess the advantages of supporting force protection, mobility and precision strike has bright application prospects of joint operational concepts, and the unique role of non-lethal weapons, concepts and capabilities. "These efforts will increase the level of existing non-lethal weapons, provide non-lethal weapons far distances beyond the range of light projection capability, and can find innovative, can provide advantages in various levels of threat and crisis and solution of non-lethal technologies and concepts. United States civil and military sector has repeatedly stressed that non-lethal weapon used in the military operations will never replace conventional destruction weapons, but for responding to the threat and the control of the military commander to provide greater flexibility. NATO has gradually begun to set foot in this very special project officially published and in 1999 the definition of non-lethal weapons: "non-lethal weapons is a clear for making people lose and disperse the crowd, while people are less likely to cause fatal or permanent damage, or loss of equipment, equipment damage, and at the same time with minimal impact on the environment. "With the United States, NA TO's Policy Committee has made it clear that non-lethal weapons are conventional weapons complement, rather than their replacement, which allow officers on the battlefield to determine what kind of weapons mostsuitable for tactical environments to avoid completely the use of anti-personnel weapons to protect the force and complete tasks. 2.2 foreign status of foreign non-lethal weapons development earlier, and the technology matures, leading international. With the rapid development of science and technology, especially the last 20 years, various high-tech applications in non-lethal weapons, non-lethal weapons have seen significant development, Germany and the United Kingdom and France and other Western countries in the area of non-lethal weapons are new products have emerged. United States has been a pioneer of new technology, in addition to continue to develop improved traditional non-lethal weapons, also vote in person a lot of human and financial resources to the development of new high-tech non-lethal weapons. Especially after the end of the Gulf war, United States naval Mcmartin's concept of non-lethal war, received the United States Government and the military's attention and support, resulting in non-lethal weapon as the center of the new development of military theory and doctrine. In addition to United States, it is also in many other countries added their own national project, aimed at evaluating new technologies for non-lethal weapons and develop solutions. But many problems remain unresolved. 2.3 starting low domestic status of China's non-lethal weapons technology, financial investment and limited, comparison of gap gap with developed countries. In China of counter-terrorism concept is from "following the" yihou only began of, non-fatal theory system and framework also to be improve, apart from need carried out non-fatal weapons of standard, and trauma ballistic learn technology research, and shock wave damage hinder value and non-fatal weapons on people of effect, basic theory research outside, also must carried out counter-terrorism information technology, and network security protection technology, and sensor and detection recognition technology, and warning detection technology, and electromagnetic pulse weapons, and laser weapons, and Sonic weapons, and non-fatal weapons and fatal weapons integrated technology, and counter-terrorism equipment technology intelligence, project of research work. At present, China's development of a non-lethal weapons are mainly concentrated in tear, combat shock Halo, kinetic energy, capture network and blinding flash on the lower level, type is not complete enough, model comparison of a single non-lethal weapons launch means backward, it is difficult to achieve against long-range, accurate, difficult to enclosed spaces for effective control and innovative, high levels of non-lethal weapons in the fight to come out. To non-lethal weapon 3 display the non-lethal weapons is based on a modern military technology of the 20th century of the history of mankind's most brilliant achievements in science and technology, biotechnology, computer technology, the rapid development of information technology, new materials technology for military use and provide a powerful impetus to the development of high technology. Its wide range of applications in the military, police, species diverse, is the new favorite of modern weapons. 3.1 non-fatal weapons of defined non-fatal weapons, also said non-anti sexual weapons, and weak anti weapons, and lost can weapons, main is means using sound, and light, and electromagnetic, and chemical, means, makes enemy personnel or weapons equipment of fighting ability lost or reduce, but does not caused personnel large casualties and weapons device serious damage of new weapons, due to has non-fatal sexual, was flaunted for "humanitarian weapons". 3.2 non-lethal weapons of category 3.2.1 and the mechanism of non-lethal weapon 1 chemical incapacitating agent, chemical loss through drive target or targeted disability, usually using chemical tear agent. CN is the most commonly used tear agent (phenyl ethyl chloride), CS (o-chlorobenzaldehyde methylene malononitrile) and OC (Oleoresin capsicum). CN is a tear that can cause respiratory tract irritation on substance can cause skin irritation. CN is Germany chemist Graeber found in 1869, most of itsuses have been replaced by CS. But it to pollution in the urban environment and cross-contamination is a very big problem. OC is an acronym for pepper oil resin. It is a red pepper food products obtained after drying powder, can act as a stimulant with a variety of Jet blast to safety to control violence or dangerous animals, restoring and maintaining law and order. Now, thanks to increasing use of OC,CN, CS is gradually being replaced. PepperBall paprika projectile is a new development in recent years OC riot control weapons. 2, against loss of kinetic energy can be achieved by projectiles in General. Kinetic energy with emission targets make it lose resistance capacity. Is one of the most familiar with rubber bullets and plastic bullets against kinetic energy projectiles. In recent years has developed a wide variety of projectiles, such as the Spring bean bundle (with lead and sand package), pain ball, ring-wing projectiles, and so on. 3, a shock loss by releasing high voltage low current electric shock the target disability. Electric shock weapons at present there are basically 4 types: Taser (Manager), including electric shocks and shock batons; this kind of electric shock weapons range is short (only an arm's length), an efficient low (only about 50% per cent), and open to abuse. Cable electric shock represented by taser gun projectiles, is in development and evaluation of radio hit projectiles and can make muscles of patients of UV laser shock weapon. 4, sound and light interference (attention shift) weapons by bright light, high intensity sound makes people temporarily to blind or deaf to distribute targeted attention, helping to achieve the purpose of control of the target. These weapons include a variety of acoustic light grenades and light projectiles, light torches, laser torches. 5, other weapon other than the above 4 categories, such as blocking nailed row, using winding technology catching NET. 3.2.2 role object-1 by non-lethal weapons, non-lethal weapon against anti-sensor sensor non-lethal weapons are mainly used to deal with intelligence collection and object detection sensor, through the optical system of attack weapons, electronic equipment, complete equipment, or system failure, not working properly. Typical anti-sensor non-lethal weapons include low energy laser weapon, high power microwave weapons and other radiation light ammunition. Rapid development of low energy laser weapon, United States, Britain, Russia, France and Germany have already come out there are several prototypes, and has some of the troops. Blinding it can interfere with, or even undermine the seeker, Tracker, target indicators, Ranger and view sight equipment, can also make people blind, disrupt, block, deter or suppress enemy action. As United States Army AN/PLQ 15 type laser confrontation system, and United States Marine Corps "saber" (Saber) 203 laser lighting device, and United States Army handheld type laser "caused by Xuan device" (Daz-er), and United States Army "riding attendants" (Outrid-er) car laser caused by blind weapons, and United States forces directed infrared interference system (DIRCM), and United Kingdom "revenge goddess" (Nemsis) directed infrared interference system, and United Kingdom laser caused by Xuan device, and Qian Soviet laser caused by blind weapons,. 2, non-lethal weapons against non-lethal weapon against personnel is the use of low energy laser weapon, high power microwave weapons, non-lethal chemical warfare agents, optical, acoustic weapons ammunition, non-penetrating warheads and other weapons, affect the operations or operational capabilities of staff, temporary disability, resulting in non-casualty battle of attrition, so as to weaken the opponent's combat strength, can even be directly reached operational purpose. Non-lethal weapons against personnel, first tried in Viet Nam war. In August 1969, after Vietnamese troops wiped out a large number of US forces, took at l Highway 824 PLEI groups positions on high ground. The US military to take immediate retaliatory action, to the Highlands, the position of non-lethal projectile fired a number of anti-personnel, all positions after a fewminutes, the army lost the battle, the US military cake recaptured positions. This weapon with so-called "humanitarian color", so interest States. At present, non-lethal weapons against personnel has the following broad categories: non-lethal "Cannon", non-lethal chemical warfare agents, non-fatal virus, non-lethal ammunition. Non-lethal weapon 3, reverse maneuvering against mobile mainly uses some non-lethal weapons have a special function of chemical substances or net-like device, prevent aircraft took off normally, vehicle normal, normal navigation of ships, equipment functioning, affect the enemy's combat operations, securing favorable opportunity for home. Typical anti-mechanized Super lubricant, Super caustic, non-lethal weapons include material embrittlement agent and combustion agent "virus". For example: Super lubricant, material embrittlement agent and fuel "virus". 4, against the infrastructure of non-lethal weapons against non-lethal weapons to power energy infrastructure, water and other strategic resources and information infrastructure and other infrastructure targets, undermining energy supply, the destruction of infrastructure, affecting the material base of the war. Typical anti-infrastructure of non-lethal weapons, including ammunition, power failure damage hydro chemical warfare agent non-deadly computer virus and non-fatal bacterial bomb, weapons and so on. 3.2.3 according to the principle of non-lethal weapon 1, laser weapons. Laser weapons are a distinct from the traditional weapons of the new concept of beam weapons. Blinding laser weapons were made of low-energy laser beam irradiation for the human eye, so that the loss of retinal, cause a temporary or permanent blindness and loss of combat effectiveness. United States maidao electronic systems company developed the "snake eyes" laser gun, was a soldier to carry and use of laser guns, shape and M-16 similar to rifle, charge to launch 2000 "bullet", its effective range to 1 km. 2, chemical and biological weapons. Biological weapons, is a traditional weapon, but the power of modern biological weapons has greatly exceeds the efficiency of biochemical weapons in the traditional sense, it can cause the enemy army team。
