What type of explosives are NOT commonly used as the main charge for IEDs?

The correct answer indicates that all types, including military, commercial, and experimental explosives, are used as main charges for improvised explosive devices (IEDs). In the context of IEDs, various explosives can be utilized due to their availability, effectiveness, and the specific requirements of the device's design.

Military explosives are typically designed for warfare, providing high energy and stability and making them a common choice for skilled individuals creating IEDs. These explosives often include well-known compounds that are reliable under various conditions.

Commercial explosives, which are used in industries such as construction and mining, offer another source that individuals may access to create IEDs. Their abundance and effectiveness for demolition purposes make them appealing for this illicit use.

Experimental explosives may be less common in everyday scenarios, but they can still be sourced or developed by individuals with the knowledge and resources. Their use reflects adaptability and innovation in the creation of IEDs.

Hence, the statement that none of these types of explosives are excluded from use as main charges in IEDs illustrates their versatility and the varied motivations behind their employment in such devices.
