How long are M762 and M767 good for once being cracked?

The M762 and M767 fuzes have a specific timeline regarding their effectiveness after being cracked due to the sensitive nature of their components. Once they are cracked, they are designed to remain functional for a duration of 15 days. This time frame allows for proper usage and handling in various operational contexts while ensuring safety and compliance with handling regulations. Knowing this critical detail helps ensure that artillery crews can manage their ammunition and equipment effectively and avoid potentially hazardous situations that may arise from using expired or compromised munitions.
