Two fuels surfaced as constants: There is a well-documented history of explosives production from analogous urea-nitrate salt solutions used in Iraq. VBIEDs use charges ranging in mass from approximately 40 pounds to tens of thousands of pounds, depending on the carrying capacity of the vehicle. Compiled from open source materials, the handbook promotes a ‘Threats’ perspective and enemy situational awareness of U. Other countries restrict access to precursor chemicals in an effort to reduce the opportunity for HMEs to be used in IEDs. Initially, groups attempt to procure commercial or military explosives if such are accessible. Denied the precursors for simple blends, they resort to processing materials to produce the feedstock of their explosives, such as by isolating AN from CAN.
Starting with these scenarios, one can 1 identify the chemicals that terrorists can use to produce each type of device and the conditions under which they can obtain them; 2 develop strategies to reduce the odds of malicious actors getting access to the precursor chemicals; and 3 ultimately, lessen the risk of either scenario by making both scenarios less likely to happen i. In the s, a large number of small dynamite bombs less than 20 lb were used in the United States. To synthesize urea nitrate, the precursor chemicals urea and nitric acid are both required; thus, urea nitrate production could be blocked in the absence of either. Email it to a friend! While acetone can be reacted with hydrogen peroxide to produce the explosive TATP, the committee did not include acetone on the short list because it is not considered a threat if appropriate steps are taken to control the peroxide component. However, any government creating controls for precursor chemicals must consider the tactics that will be developed in response.
For the third criterion, chemicals judged independent in syntheses I were assigned a higher priority, and those judged dependent D were assigned a lower. By the s, the use of HMEs in smaller sudy was growing.
The evolution of Suicide Car Bombs examined
Inapproximately 19 years after its introduction, PIRA discovered that crushing the CAN prills into a powdered form using either industrial strength coffee grinders or barley crushers eliminated the need to isolate purified AN.
The remainder of the groups shown in Figure include bomb builders in the Iraq and Afghanistan conflicts as well as the newer factions encountered with the rise of Vbiee and other extremists.
They utilised a wide range of colours, sometimes even bright hues fbied seem counter-intuitive from a camouflage viewpoint. Every chemical on the list had been used in a bombing or in IED production in some capacity at least once. At the same time, they also used up-armored SVBIEDs against well-defended targets, in areas where they had an increased presence and fighting was especially tough.
In this study, the committee chose to conduct an in-depth examination of the Group A precursor chemicals. Share this Article Like this article? The final evaluation is provided in Table Powered by WordPressMandigo theme by tom. Based on this trend, the committee chose to cast a wider net, by looking at precursor chemicals that can be used to manufacture VBIEDs or PBIEDs, and further prioritized the precursors using three criteria: In contrast, nitric acid can be used to synthesize a variety of other explosive materials.
The committee assigned each chemical either a higher or lower priority for each criterion. The Hellenic Arms Control Centersimulated the explosion of 75 kilograms of ANFO on the same ground zero in order to assess the claim of the terrorists.

In the s, a large number of small dynamite bombs less than 20 lb were used in the United States. The VBIED can either vbued parked and then sttudy detonated, or it can be driven by a suicide bomber who ultimately controls the detonation mechanism.

Two fuels surfaced as constants: Generating a Short List of Precursor Chemicals Every exercise in prioritization, including this winnowing process, has an inherent degree of subjectivity.
Such materials were not accessible in the United Kingdom, but PIRA atudy able to obtain farm chemicals to replace the dynamite. Understanding terrorism spans foreign and domestic threats of nation-states, rogue states with international or transnational agent demonstrations, and actors casf specific strategies, tactics, and targets. They often use the same or similar vehicle models that are fitted with identical armour kits, and a lot of time the IEDs that make up the main payload are standardised as well.
Improvised explosive devices IEDs are a vbisd of unconventional explosive weapon that can be deployed in a variety of ways, and can cause loss of life, injury, and property damage in both military and civilian environments. While acetone can be reacted with hydrogen peroxide to produce the explosive TATP, the committee did not include acetone stusy the short list because it is not considered a threat if appropriate steps are taken to control the peroxide component.
VBIEDs use charges ranging in mass from approximately 40 pounds to tens of thousands of pounds, depending on the carrying capacity of the vehicle.
Do you enjoy reading reports from the Academies online for free? This handbook supports operational missions, institutional training, and professional military education for U. To generate a more-focused short list of precursor chemicals, the committee considered two variables: In this situation, the use of covert S VBIEDs does not make sense anymore, as they most likely would be disabled before reaching the target.
Of the two, urea is much more commonly available than nitric acid, and the only explosive it can be used to produce is urea nitrate. While both subtypes were used extensively, they each served a different purpose.
The handbook promotes an improved understanding of terrorist incident objectives, motivation, planning, and conduct of operations. Under the second criterion, past usage of a precursor was taken as an indicator of its continued potential to be applied in IEDs in the present and future.
