Which of the following conditions requires a two-year examination for explosive drivers?

Condition Code J indicates that the explosives are unserviceable and not eligible for reissue, which necessitates a two-year examination to ensure compliance with safety protocols and determine whether the items can be disposed of or otherwise managed appropriately. This code encompasses mishandled or deteriorated munitions that may pose safety hazards if not regularly assessed.

In the context of ordnance management, a two-year examination serves as a critical process to identify potential risks associated with the stored items and maintain operational safety. It is a crucial practice in ordnance handling, ensuring accountability and the safe management of explosives over time.

Other condition codes, while relevant to the categorization and handling of ordnance, do not specifically stipulate the same requirement for a two-year examination.
