What is typically used for the main charge in an IED?

The use of commercial explosives for the main charge in an Improvised Explosive Device (IED) is prevalent due to their reliability, effectiveness, and availability. Commercial explosives, such as dynamite or ammonium nitrate fuel oil (ANFO), are designed specifically for explosive purposes, providing significant energy output, which can result in considerable blast effects.

Commercial explosives are often chosen because they are manufactured to meet specific safety and performance standards, allowing for more predictable detonation characteristics compared to other substances. This predictability is crucial in the construction of IEDs, where the intent is to maximize damage while ensuring the device functions as intended.

Other substances can be used in IEDs, but they may not provide the same level of performance or stability. For instance, gasoline can be flammable but does not have the effective explosive power that commercial explosives possess. Homemade mixtures, while sometimes effective, can vary widely in effectiveness due to inconsistent quality and lack of precise formulation. Chemical agents are typically not used as the main charge in IEDs, as their primary function is usually related to toxic effects rather than explosion. Hence, the use of commercial explosives represents the most reliable choice for creating a powerful explosive device.
