Danger Close for mortars and artillery is within how many meters of friendly troops?

• A. 750 m
• B. 600 m
• C. 1000 m
• D. 900 m

Answer: (B)

Danger Close defines how near indirect-fire rounds can land to friendly troops while still being considered a close-support mission. For mortars and artillery, the standard Danger Close radius is 600 meters. That means when fire is planned or adjusted within about 600 meters of friendly positions, extra safety measures, coordination, and potentially higher-level approval are required to manage the risk to those troops. The 600-meter boundary is chosen because it balances the need to support troops in near contact with the realities of fragmentation and overpressure from artillery and mortar rounds. Distances beyond that (such as 750, 900, or 1000 meters) are outside the standard Danger Close; they still require careful fire planning, but do not invoke the same heightened Danger Close constraints.
