Which card is specifically designed to aid personnel during a bomb threat scenario?

The choice of the Threat Reaction Card as the most appropriate option for aiding personnel during a bomb threat scenario directly aligns with its intended purpose. The Threat Reaction Card is specifically designed to provide immediate and clear actions that personnel should take in response to potential threats, including bomb threats. This card typically includes concise instructions that can help individuals remain focused and calm under pressure, ensuring they follow the correct protocols to maximize safety and effectiveness during such critical situations.

In contrast, the Incident Report Form is used for documenting incidents after they occur rather than providing real-time guidance during a crisis. The Emergency Procedures Guide contains broader emergency protocols but may not focus specifically on bomb threats, making it less effective for that particular purpose. AF Form 440 serves its own purpose within the Air Force but does not directly pertain to responses in bomb threat scenarios. Therefore, the Threat Reaction Card stands out as the key resource for personnel faced with such an emergency.
