After deactivation, which term would describe the state of a munitions item?

The term that describes the state of a munitions item after deactivation is "inactive." In this context, once a munitions item has been deactivated, it can no longer be utilized for its intended purpose or pose a danger, thus entering an inactive state. This reflects that the item is removed from active service and is no longer functional as a munitions piece.

In contrast, "active" describes a state where the munitions item is operational and can be deployed or used in activities. "Transitional" suggests a changing state or process, which doesn't accurately represent the finality of deactivation. "Secured" indicates a state where the munitions item is stored or protected but does not specify whether the item is still functional or not. Therefore, "inactive" is the most fitting term to describe the condition of a munitions item post-deactivation.
