3
Background

• Non-Military Action
• Used to Distract, Disrupt, or Delay
• Materials For Detonation Vary
• Three Categories
• Package Type
• Vehicle-Borne
• Suicide Bomb

4
History

• First Example Belarus Vs. Germany WWII
• Vietnam
• Grenade In A Can
• Rubber Band Grenade
• Mason Jar Grenade
• Northern Ireland
• Afghanistan
• Iraq

5
Package Type IED

• Simple IED
• Thrown from overpasses or in front of Vehicles
• - Detection
• - Trigger
• - Disarming

6
Package Type IED-Detection-

• Employed along supply routes, in potholes
• - Dog Detection for Chemical IED
• - Radiation
• - Image Registration

7
Package Type IED

• Time delayed trigger and Command detonated
• - Cell phone
• - Garage Door Opener
• - Simple Timers

8
Package Type IED

• Disarmament
• - 23-ton "Buffalo"
• - Dragon Runner SUGV

9
Vehicle Borne IEDs

• Use the Vehicle as the package or container of
  the device
• Trigger
• -Park and then KA-BOOM (By radio control)
• -Crash into the crowd/city (By Driver)

10
Vehicle Borne IEDs

• Detection -Weight of the vehicle (remember The
  Italian Job?) -ESSEX system (Extremely Sensitive
  and Selective
• Explosives detector)2 -lase
  r ionization mass spectrometry (analysis line
  spectra) -special trained dogs3.

11
Vehicle Borne IEDs

• Disarmament
• -same way of disarming of a Package
  IDE -except you might be doing that in a car

12
Suicide Bomb IED

• A device worn by an individual that employs a
  high-explosive/fragmentary effect

13
How does it work?

• The most common form of a Suicide IED Bomb is
  known as a suicide vest
• Initially, the device was a square block of
  
  explosives worn in the chest and the belly
  
  area. Gradually, the device evolved into a
  
  heart shaped block of explosives placed just
  
  above the navel
• These vests have no/little electronics,
  
  making it difficult for security agencies to
  
  develop counter-technologies to detect these
  
  devices
• Can be made from common items found in
  your
  local stores such as wire, batteries,
  
  switches and chemicals
• Generally a timer, hand trigger or remote
  initiation systems such as wireless
  radio-controlled system is used to detonate the
  explosives

14
Detection

• Around 2003, police officials used dog sniffers
  to detect individuals carrying IEDs but over the
  last few years, terrorists have improved there
  technology to avoid being detected by these dogs
• At airports, computed tomography and X-ray
  backscatter imaging as well as high-performance
  sensors have been used that can detect and help
  interpret sounds, odors, or even images from
  within the bomb
• More suitable devices for large amounts of cargo
  are nuclear-based technology such as thermal
  neutron activation, pulsed fast thermal neutron
  activation and nuclear quadruple resonance

15
Triggering

• Timers
• Hand Trigger
• Wireless-remote initiation systems

16
Disarming

• Explosive Ordnance Disposal technicians (EODs)
  use 75-lb bomb suites and bulletproof helmets to
  shelter themselves from the worst of an
  unexpected blast
• In the event of a terrorist threat, negotiation
  is used, otherwise deadly force is normally the
  only other option

17
Conclusion

• IEDs Fall Into Three Categories
• Material And Complexity Vary
