FAQ
Frequently Asked Questions
IED stands for 'Improvised Explosive Device'.
Not exactly. While both are explosive hazards, a landmine is usually a factory-made, mass-produced weapon designed to be buried. An IED is makeshift, often assembled locally, and can be deployed in many ways (roadside, vehicle-borne, worn).
Because the device is crafted using non-standard, often everyday materials (like fertiliser, pressure cookers, or mobile phones) in a non-military setting, unlike professionally manufactured grenades or shells.
Primarily in news reports about terrorism or insurgencies, military documentaries, and security or political discussions. It is not a term used in everyday conversation.
