What is the term for items that have had their explosive material removed and not replaced?

The term used to refer to items that have had their explosive material removed and not replaced is "deactivated." This term specifically indicates that the explosive components have been taken out of the munition, rendering it safe and non-functional in terms of explosive capability. Therefore, deactivated items are no longer capable of detonation or functioning as intended in their original role.

While "empty," "defused," and "unloaded" may seem relevant, they do not accurately capture the specific condition of the munition. "Empty" generally refers to a lack of content in a broader sense but does not imply that explosive material was specifically removed. "Defused" refers to the process of making a munition safe, particularly by disabling its detonation mechanism, but this does not necessarily mean that the explosive material has been removed entirely. "Unloaded" is often used in other contexts but not specifically in reference to munitions with removed explosives.

In summary, "deactivated" is the precise term for items that have had their explosive material removed and signifies that they can no longer function as explosives.
