What is the minimum safe firing distance for the M203 during combat?

The minimum safe firing distance for the M203 grenade launcher during combat is indeed 31 meters. This distance is established to ensure the safety of personnel from potential fragmentation and blast effects that can occur when the grenade is fired.

Firing at a distance less than 31 meters increases the risk of injury to both the shooter and nearby troops due to the possibility of the explosive round detonating too close to friendly forces. This specific distance has been determined through extensive testing and operational experience, ensuring that the risk is mitigated while still allowing the weapon to be effective in the intended combat scenarios.

Other distances listed, such as 10 meters, 50 meters, or 100 meters, either do not accurately reflect safe operational practices or do not align with established military standards for employing the M203 in a combat environment.
