The M67 grenade has a kill radius of 5 meters and a casualty radius of 15 meters. Which statement is true?

• A. The kill radius is larger than the casualty radius
• B. The casualty radius is larger than the kill radius
• C. They are the same
• D. There is no casualty radius

Answer: (B)

The test is about comparing two types of blast effects: kill radius and casualty radius. For the M67 grenade, the kill radius is 5 meters, meaning within that distance the likelihood of fatal injury is high. The casualty radius is 15 meters, meaning injuries (not necessarily fatal) can occur out to 15 meters. Since 15 meters is larger than 5 meters, the true statement is that the casualty radius is larger than the kill radius. This reflects how blast and fragmentation can cause injuries farther from the device even though the most likely fatalities occur closer in. The other options conflict with the given numbers or deny the existence of an injury range.
