Final answer:
An AA&E storage facility must be resistant to forced entry for a specific period of time, typically determined by regulations and standards set by the governing body or organization responsible for overseeing the facility.
Step-by-step explanation:
An AA&E (arms, ammunition, and explosive) storage facility must be resistant to forced entry for a specific period of time. The exact duration of resistance will depend on the regulations and standards set by the governing body or organization responsible for overseeing the facility.
For example, in the United States, the Department of Defense sets standards for AA&E storage facilities. According to DoD Manual 5100.76-M, a Type I AA&E storage facility must be resistant to forced entry for 20 minutes. This means that it should be able to withstand attempts at unauthorized entry for at least 20 minutes.
Other countries and organizations may have their own specific requirements for AA&E storage facilities. It is essential to consult the relevant regulations and standards for the specific jurisdiction or organization in question to determine the required duration of resistance to forced entry.
