What is the casualty radius of the M67 grenade?

• A. 15 m
• B. 5 m
• C. 25 m
• D. 10 m

Answer: (A)

Casualty radius describes how far from a grenade you can expect injuries from the fragmentation and blast, not just the immediate center. It reflects how far the flying fragments and the overpressure can cause harm to personnel.

For the M67, training references commonly cite a casualty radius around 15 meters. That distance represents the typical zone where fragmentation injuries are likely, making it the best match among the given options. The other distances don’t align with the standard reference for this grenade: 5 meters is more characteristic of the near-center, high-risk area; 10 meters is smaller than the standard casualty reach; and 25 meters generally exceeds the usual casualty envelope for standard issue fragmentation grenades.

Remember that real-world conditions—terrain, cover, and protective gear—can affect actual risk, but the 15-meter figure is the conventional training reference for planning and safety.
