Which distance is the M203 arming distance?

• A. 6 meters
• B. 20 meters
• C. 14 meters
• D. 10 meters

Answer: (C)

Arming distance is the minimum distance the grenade must travel before its fuze arms, ensuring it won’t detonate too close to the shooter. For M203 40mm high‑explosive rounds, that minimum distance is 14 meters. This safety margin means the fuze arms in flight after traveling at least 14 meters, and the round will detonate on impact (or after its delay, per the round’s fuze). Distances shorter than 14 meters aren’t safe because the fuze may not arm properly, risking a near‑shooter detonation; distances longer than 14 meters are fine, but the defined arming distance itself is 14 meters.
