What is the recommended action in response to an overhead flare?

When responding to an overhead flare, assuming a prone position is the best action to take for several reasons. Flares are often used to indicate a nearby presence or provide illumination, and while they can signal danger, they do not typically denote imminent threat in the same way as gunfire or explosions. By getting into a prone position, you minimize your exposure to potential threats and make yourself a smaller target, which enhances your personal safety.

Assuming a prone position also allows you to remain low to the ground, which can help you observe the situation without being immediately visible. This is critical in a combat scenario where staying concealed is important for both assessing the situation and preparing for any further developments.

In contrast, waving a signal flag may attract unwanted attention, while hiding under available cover could limit your view and situational awareness. Retreating to a safer distance can be appropriate in certain contexts, but it may not always be feasible depending on surroundings and the immediate threat level. Thus, taking a prone position strikes the best balance between safety and situational awareness in response to an overhead flare.
