What is the maximum range of the M203 grenade launcher?

The maximum range of the M203 grenade launcher is 400 meters for a high explosive round, but it can be extended to about 500 meters under specific conditions, although 400 meters is the standard effective range for a direct fire. The choice of 415 meters reflects the approximate maximum range for both the grenade launcher and the types of grenades it fires. This understanding is crucial for operational planning and engagement scenarios within the battlefield, ensuring that personnel can effectively utilize the M203's capabilities while maintaining tactical advantage. Remember, this is not the effective range for all types of rounds, as some specific rounds may have different optimal ranges for use based on their ballistic characteristics.
