What type of IED is activated by a command from a remote location?

The correct answer is Command Detonated IED. This type of improvised explosive device (IED) is designed to be triggered by an individual from a remote location, allowing them to control the timing and target of the explosion. Command detonation can be accomplished through various means, such as radio signals, wires, or other remote activation devices, making it distinct from other types of IEDs that may have other triggering mechanisms, such as timers or pressure plates.

In contrast, a House Borne IED (HBIED) is typically concealed within a structure and may not necessarily be activated remotely. Similarly, a Vehicle Borne IED (VBIED) is a device placed within a vehicle, which can be detonated, but its operation might not rely on a command from a distance; it could be designed for suicide attacks or timed explosions. Lastly, a Suicide Vest is directly worn by an individual and is often detonated by the wearer, rather than being under external control.

Thus, the defining characteristic of a Command Detonated IED is its operational control from a distance, which situates it distinctly in the context of tactical operations and explosive devices.
