What is the standard danger close distance for CFF?

• A. 100 meters
• B. 200 meters
• C. 600 meters
• D. Unknown

Answer: (C)

Danger close describes firing near friendly forces where blast effects could endanger them. For a Call For Fire mission, the standard distance used is six hundred meters. This threshold reflects the typical blast and fragmentation radii of conventional artillery and mortar rounds and serves as a signal to implement extra safety measures—such as confirming target ID, adjusting fire to avoid friendlies, and choosing appropriate munitions or fire discipline—before delivering fire within that range. Distances like one hundred or two hundred meters are closer than the standard danger close envelope and would require even stricter controls or different approaches, while unknown isn’t applicable because a defined standard exists.
