At what minimum distance is an impact considered to be 'Danger Close'?

'Danger Close' refers to the minimum distance from friendly forces at which indirect fire, such as artillery or air support, can be executed without posing an unacceptable risk to those forces. This term is crucial for ensuring the safety of troops while still being able to provide effective fire support in combat situations.

The correct answer indicates that 600 meters is the established threshold for 'Danger Close.' When the impact of fire is unleashed at this range, it is understood that the risk of harm to friendly personnel is significant but manageable, underlining the importance of careful coordination and communication between infantry units and fire support assets.

Understanding this distance is vital for Marines who must be aware of their surroundings and the potential risks associated with calling for and receiving indirect fire support. This knowledge enables them to make informed decisions in the heat of battle, ensuring that they can effectively utilize available firepower while maintaining troop safety.
