Select all items not included in the military munitions' definition.

The correct answer includes the understanding that nuclear weapons and components with warheads are indeed classified as military munitions. In the context of the military munitions definition, anything related to nuclear arms falls under the category of munitions because they are designed and produced specifically for military use.

By contrast, other items such as munitions not produced for Department of Defense (DOD) purposes or wholly inert items do not fall within the standard military munitions definition. Munitions not produced for DOD purposes are excluded because they do not serve the official objectives or missions of the U.S. military. Wholly inert items, which are incapable of causing detonation or destruction, are also not considered military munitions since they lack the explosive or harmful properties typical of munitions. Additionally, while improvised explosive devices (IEDs) could be seen as military munitions in a combat context, their generally unauthorized, ad hoc production separates them from the formal definition of military munitions as recognized under accepted military standards.

Understanding this context clarifies why nuclear weapons and components with warheads are correctly included in the military munitions definition, making the selection of this answer vital.
