IMPROVISED
EXPLOSIVE
DEVICES
(IED)
1
Definition
An IED is a device, assembled by an
organization or an individual in
contravention to the existing
rules of Law of Nation adopting
unconventional or semiconventional methods of
assembling a standard device,
ammunition/explosives or
commercial, with a criminal/antinational intention.
The design of an IED will depend on the lethality of a bomb

IED


The effects of an
IED explosion are not
standard and predictable
The effects will vary in
each case, depending on :
 Components
 Quality of explosive
 Casing
 Quantity of splinters

Initiation Mechanism
The switch is a mechanism
incorporated to ensure
initiation of an IED in a
predetermined pattern so
as to ensure success in
destroying the target in
a well deliberated
manner.
