Which weapon has a minimum arming distance of 14-38 meters (46-125 feet)?

• A. M249
• B. M2
• C. M84
• D. M203

Answer: (D)

The concept here is how explosive rounds have a safety requirement before they arm. Some grenadier rounds sit in a safe mode until they travel far enough to arm, preventing detonation near the shooter. The M203 fires 40mm grenades with fuzes that require a minimum flight distance to arm, typically around 14 meters and up to about 38 meters depending on the round. That makes 14–38 meters the documented minimum arming distance for the 40mm grenades used with the M203. The other weapons listed fire rounds that don’t use this same arming-distance criterion in their standard ammunition, so they don’t match this specific specification.
