What term describes ammunition requiring test or modification?

The term that describes ammunition requiring test or modification is "Test/Modification." This classification refers to munitions that have not yet met the standards for operational use and therefore need additional evaluation before they can be deemed reliable or effective. This process ensures that any potential issues are identified and rectified prior to deployment, ensuring safety and performance during operations.

In contrast, categories like "Serviceable" indicate that the ammunition is ready for use, while "Unserviceable" denotes that the munitions are unsuitable for use due to significant faults or damage. The term "Suspended" typically refers to ammunition that may be temporarily taken out of use but not necessarily because it requires testing or modification. Understanding these distinctions helps ensure proper handling and operational readiness of ammunition in the field.
