For which reason would classified material be destroyed according to the emergency destruction plan?

Classified material may be destroyed as part of an emergency destruction plan primarily to prevent it from falling into the hands of unauthorized personnel, especially in the event of capture by an enemy. This action is taken to protect sensitive information that could jeopardize national security or operational effectiveness. When classified materials are at risk of being obtained by adversaries, destruction serves as a critical safeguard against potential threats.

While materials can certainly become obsolete and might be destroyed for administrative reasons, the urgency of the emergency destruction plan is centered around the risk of enemy capture. Therefore, protecting classified information from adversaries takes precedence, highlighting the importance of maintaining operational security at all times.
