U.S. soldiers for bomb disposal training.
reflect the U.S. military in Baghdad, Iraq war combat film “Hurt Locker” has become the biggest winner in this year’s Academy Awards. U.S. military bomb disposal unit real look like? Stripped the veil of American movies, this time facing life-threatening occupation, the number of unknown story?
harsh conditions as the application, training dates long, so the U.S. military bomb disposal experts are scarce resources. Currently only 4000 U.S. bomb disposal experts. Most of the time, by the EOD bomb disposal robots to complete. Only when the robot can not solve the problem, bomb disposal experts will personally play.
the world’s countries have a bomb disposal unit in the military establishment, in addition to the U.S. military bomb disposal unit has repeatedly experienced real test, the United Kingdom, Israel, Spain and other countries of the bomb disposal unit are also some low- intensity military conflict has accumulated rich experience.

training is very strict
bomb disposal unit out rate of 85%
improvised explosive devices in Iraq and Afghanistan is the face of destructive weapons. Removal or detonation of explosive devices need to bomb them experts in explosives disposal teams composed. Was awarded the Oscar for best film award, “Hurt Locker” is described in such a group.
according to the U.S. military branches of the military division of the U.S. military bomb disposal unit are the preparation of engineering sequence, commonly referred to as explosive ordnance disposal teams. Bomb disposal experts have been more than 100 pre-years of special training, usually 12 months to 16 months between.
bomb training from the fireworks start
to become a qualified U.S. military bomb disposal experts, who need to apply numerous tests. First, the applicant’s fitness is better, no color blindness, but also by mechanical classification test. In the physical tests, applicants have to wear more than 30 kilograms of heavy protective clothing to complete the tasks.
preliminary examination by the soldiers will then be sent to bomb the school for further training. Accordance with the process, these soldiers to go through at least one year of hard training. During the training, they have to learn terminology explosion, bomb disposal methods and other techniques. Bomb training attrition rate as high as 85%, only a few people through a final examination.
according to U.S. military engineering training tutorial, just enter the bomb squad of recruits, the first study will be repeated a number of explosive devices that have been invalidated. Then they will slowly into contact with some smaller explosive devices, such as firecrackers.
so, even if the bomb failed bomb disposal experts would not be much damage. Only the technology is mature, they will start training defuse other explosives.
In addition, training courses in mental training is a vital link. With a retired U.S. military bomb disposal experts as saying, “We must have the ability to make decisions under pressure.”
U.S. military bomb disposal unit started to increase gradually the pace of development has invested billions of dollars for training the bomb squad, bomb disposal robots to buy.
Typically, each U.S. military bomb disposal team needed seven people, bomb disposal tasks in the implementation of their respective different division of labor. But in recent years because the U.S. military manpower tension, often bomb squad in the implementation of tasks, usually only three act together. An experienced bomb disposal experts as captain and two soldiers as support staff.
take out “buffalo”
in Iraq and Afghanistan, the U.S. military bomb disposal unit has three main tasks: the first is the protection of VIPs traffic safety, and the second is the removal of improvised explosive devices have been found, and the third is after the explosion at the blast site investigation, looking for clues and so on.
bomb disposal unit is a heavy armored vehicles used by the mine-protected vehicles, these vehicles usually have some strange names such as “buffalo”, “Puma” or “husky.” They placed on board all the necessary equipment: explosives disposal robot, explosives disposal services and water and food.
bomb very rude
rocket forward to open up channels
U.S. air and sea forces will have their own bomb disposal unit, police can generally be divided into two lines.
“Hurt Locker” in the main character in the city work, more like the police bomb squad. Field army bomb disposal means much more than police brutality, ground forces attacked the enemy on the route have been mine, not one of modern engineering to demolition. It is common practice to use mine rocket launch in a row with the rocket blasting cord leap over the minefield and then detonated the blasting cord. By violent explosions, can clear a channel.
bomb fuse almost all modern electronic. If only the electronic detonation, of course not, tear down or destroy the power wire fuse can be so disabling. But who will carry out bomb-making technical improvements to increase the tamper function. Therefore, the bomb disposal experts, in order to find out exactly what all of the bombs is not possible.
course, this does not mean you can not bomb, and now the more common approach in two ways. One is a kind of dry ice or liquid nitrogen spray fuse parts of things, it quickly cooled near absolute zero degrees Celsius in the case of most electronic components will fail, so that you can ignore the fuse tamper function.
Another idea is to contrast with thousands of degrees Celsius temperature flame burst fuze, the fuse in less than 1/10 seconds to melt completely, this approach is common in United Nations peacekeeping force in de-mining experts. Relative to the poor to carry dry ice storage, the high-temperature flame is obviously easier.
task very dangerous
at least 64 people were killed by a bomb
about the current U.S. military 4000 bomb disposal experts. U.S. data show that, in Afghanistan and Iraq, about 50% of IE improvised explosive device exploded in the bomb experts dismantled before removal. But the U.S. military bomb technology to improve at the same time, Afghanistan and Iraq and other places of resistance are evolving.
only in the past year, the power of roadside bombs in Afghanistan increased dramatically. In 2008, about 40% of the IED explosive device weighing more than 25 pounds. 2009, to 75%, of which a considerable portion of the weight of more than 100 pounds. Bomb technology are becoming increasingly complex, with multiple trigger device, and deliberately set up the second bomb exploded, the blast site specifically for the investigation of bomb disposal experts.
Last week, a Taliban commander said in an interview admitted that they had received bomb training, one of the main content is to learn how to use the secondary explosive devices, the first aim is to After the explosion, bomb experts to the scene of killing.
annual salary of up to several hundred thousand dollars
fatal incident with the increase in roadside bombs, bomb experts in Afghanistan and Iraq have become hot. Private contractors are willing to pay big bucks to recruit them, you can easily reach hundreds of thousands of salary dollars. However, this pressure is not the work of a great danger for everyone, every day bomb disposal experts are all at risk of losing limbs and lives at risk.
no doubt, bomb disposal experts and become a thorn in the flesh militants. Therefore, the bomb disposal expert is also a very dangerous arms. According to statistics, there are at least 64 bomb disposal experts in Iraq and Afghanistan sacrifice. There are statistics found that the majority of bomb disposal experts were not in direct bomb killed when a bomb, but the way the escort killed by a roadside bomb.
retired U.S. soldiers about life in Baghdad Bomb
a “cat and mouse” game
retired Chinese-American soldier serving in Baghdad Shao-Hua Liu for a long time, the task is to exclude mines. “U.S. military department responsible for excluding bomb called the bomb squad, is an upgraded version of mine group. Excluded from roadside bombs nature of the work connected with the removal of mines,” Hurt Locker “in the plot basically true.” Shao-Hua Liu said.
In his view, the bomb is a cat and mouse game, with the “bomb squad” Bomb technological progress, bomb-maker’s technology is also progress.
How to find a bomb:
the road to clean and take photo comparison
LIU Shao-hua said that over and over refuse to identify roadside bombs, logic is very simple, “Those things should not be here.” U.S. military patrol routes relatively fixed, the record of the patrol area has photographs, for example, a poultry market, usually on the ground are dead animals, if one day suddenly a pile of gravel, very suspicious.
usually requires U.S. businesses regularly patrol the area clean up garbage, so the patrol road relatively clean, if suddenly a bunch of garbage, it will immediately attract attention.
how the bomb:
first set and then be removed without protective circle split
encounter In both cases, according to standard procedures, the establishment of U.S. military protection is usually the first lap, then bomb disposal experts to enter the venue. If you find explosives, they first detect the type of explosives, and then decide whether to dismantle or detonate, clean up the site after work.
Iraq is a tribal form of society, armed tribal elders are respected for many, something the government can only help the elders often. “Some local people are usually hard to know when and where attacks will occur so near the station in a good relationship with them is very important.” Shao-Hua Liu said.
learn to refine the attackers ideas
In addition, we must learn to refine the attackers ideas, to understand what kind of place they need to know to avoid a certain period of time where to go. Usually the last to learn to observe their more frequent access to lots of law, “If a road has a lot of people usually go, and suddenly one day only one or two people waiting to see, do not be surprised you do?”
another Chinese Shao-Hua Liu a soldier is not so lucky. June 2009, serving in Iraq, the son of immigrants from Hong Kong Aidemengluo in the removal of a roadside bomb, the bomb were killed by. 23-year-old Aidemengluo like his immigrant parents as smart and hard, well-known Rochester Institute of Technology gave him a full scholarship, but he refused.
animals Bomb Unit
mice mine cat as bodyguards
researchers found that, mine has a mouse in the unmatched talent, especially those living in Africa, in Mozambique is extremely keen sense of smell hamster, skill than sniffer dogs is also fast, able to accurately locate mines position, thus the local government demining project “hero.”
According to reports, a mine detection rats within 30 minutes of at least 100 square meters of minefield detection, and de-miners in the mine in the same area a day time. This “mine-mouse” with the sense of smell is very sensitive although bigger in size, but will not detonate mines.
Similarly, Colombia is also the world’s first established in 2008 a “mine detection rats force”, the group can sniff out explosives in the laboratory rats receiving high-intensity training to detect scattered Colombia’s anti-personnel mines. Colombia is the world’s most heavily mined countries.
Interestingly, the first mouse mine in Colombia troops, including 14 rats and three cats. According to reports, the cat can not be mine own activities, but this group of trained cats, can protect mice from these mine attack other cats.
variety of mine, “tools” complement each other
mine detection dogs has become one of the most common means of mine clearance. According to reports, Currently there are more than 25 organizations worldwide use of mine detection dogs, there are two main reasons: First, if used correctly, mine detection dogs faster than manual clearance, and more economical.
Additionally, mine detection dogs can detect mines with low metal content and high metal mixture mines, such as railway lines mines. Many international mine clearance organizations to adopt an integrated approach such as combined use of mechanical pre-clearance, manual clearance and mine detection dogs, a variety of mine, “tools” complement each other. In this combination, the use of mine detection dogs are an important part.
armored bulldozers cost one million U.S. dollars
countries in the world after another bomb disposal units are equipped with bomb disposal robots, bomb disposal experts in order to minimize the dangerous. It is understood that the first bomb disposal robot in the 1970s, when the British Army bomb disposal experts are suffering from the Irish Republican Army bomb attacks, bomb disposal robots came into being.
bomb squad can be manipulated by remote remote control robot, in order to achieve the purpose of reducing casualties. All-metal construction of the bomb disposal robots, often with a camera, a distance of bomb disposal experts to manipulate the robot arm through the screen to complete the bomb task.
current foreign military equipment, bomb disposal robots, usually about 47 cm high, weighing 3 kg. As a bomb disposal robot used by many of the objective conditions, so Britain and other countries in Afghanistan and Iraq EOD promote the use of armored bulldozers.
U.S. military bomb disposal experts used a high degree of protection armored vehicles are designed to dig out buried bombs or barrier net, each military vehicle costs up to $ 1 million.
U.S. custom in recent years from a heavy Israeli armored bulldozers, with full armor and bulletproof glass cab, engine cooler, hydraulic blade cylinder and hydraulic lines and other important components to install the armor. It can be located in a large roadside bomb pushed to the side, to follow-on force to open up the impact of the road.
service weight 40 kg bomb built air conditioning
most of the time, by the EOD bomb disposal robots to complete. Only when the robot can not solve the problem, bomb disposal experts will personally play. In this case, the bomb defusing experts put service first, and only in this work can be completed with the help of his comrades. EOD is a physical work wear clothing, because the weight of the clothes themselves, there were 40 kg.
EOD service by the high-tech synthetic material, a total of two layers: the outer layer of hard, relatively soft inner layer. Hard outer layer of people from shrapnel wounds; soft inner layer to protect soldiers from blast damage.
once put EOD suits, Bomb disposal experts will accelerate the speed of action, because his body temperature will continue to rise. Every 15 minutes, the EOD service will rise 10 degrees Celsius temperature. Therefore, the bomb disposal soldiers, the EOD service within the fire protection layer is their savior. Fire protection layer and the internal water-cooling unit like the suit, it has a pumping system, from a special bottle in the extraction of water, so that the soldiers of the body cool down.
Iraq in response to hot dry weather, the U.S. military returned to the bomb disposal unit is equipped with a server installed in the explosion on the split air-conditioning. But wear clothing that does not mean 100% safe EOD, bomb disposal experts only increased the chance of surviving. If I run across powerful explosion, bomb disposal expert was doomed.
global military bomb disposal unit Competition
City Bomb experienced
into the establishment of the world’s first one in British bomb disposal units. Outstanding performance in World War II British bomb disposal units, after the war continue to accept new challenges. Before and after the 1970s, the Irish Republican Army bomb placed frequently in the United Kingdom, the British bomb disposal unit in the rapid growth in this environment.
countless bomb in combat, the British accumulated rich experience in urban bomb, technically quite a breakthrough. For example, a bomb disposal unit allotted a special explosion-proof clothing, to reduce casualties in the explosion; for the discovery of a bomb, placed in a special explosion-proof when handling drums, these are the pioneering British bomb disposal unit.
British Ministry of Defense has demonstrated a high-tech bomb disposal robots, “Long Departed”, it can carry in a backpack. Under the control of the operator, “Long Departed” in a variety of complex terrain on the move, and even climbing stairs and open the door. Robots installed four cameras, images can be returned to the operator.
founding of Israel after the war has been a common occurrence. Palestinian resistance groups frequently use roadside bombs and other explosive device attacks on Israeli targets, prompting Israel to build the world’s most outstanding one bomb disposal unit.
to prevent terrorist attacks, whether at home or in the occupied territories against the Palestinian people’s resistance, are inseparable from a bomb disposal unit. Israel also has its own bomb Henzhao. For example, for suspected possession of a bomb houses, they would use armored bulldozers pushed directly to the house, so as not to cause casualties.
army bomb disposal unit of Paris in 2006, conflict in the creative use of armored bulldozers, with its huge blade cleared with 200 to 500 kg of many explosives, improvised explosive devices. Army after the war report, with special emphasis on the armored bulldozer “is the army’s effective strength without the loss of several key.” It is also inspired by the army, the U.S. began to purchase Israeli arms dealers, this armored bulldozers.
battlefield combat experience up
U.S. domestic environment to “secure” some, but they are on Earth four troops, the garrison for extreme resistance either. Far has the Vietnam War, nearly there from 2003 into the Iraq quagmire. The former is a battle on the battlefield, which is basically an outright civil bomb attacks. It can be said, is Iraq’s long stalemate, the U.S. bomb disposal unit also have more opportunities to show his face.
Americans bomb technology was particularly “deep pockets.” For example, the “picture mine” category of the chain of explosives, the U.S. military creatively caliber rifle with a large mine. Again, in response to hot dry weather in Iraq, the U.S. military returned to the bomb disposal unit is equipped with a server installed in the explosion on the split air-conditioning.
Spain’s bomb disposal unit also has a high visibility, active in Spain as Basque separatists ETA, etc. molecules, they often install some improvised explosive devices. Especially in the last century, 80-90 years, the attacks peaked in Spain bomb disposal unit is in such an environment to grow up.
Spain’s national police, gendarmerie and the Basque autonomous police force has its own bomb disposal unit. Typically, the explosive device involved in civil security to the State Police handle the rest by the military police and the Basque police processing.
