Final answer:
The maximum effective range of the M16A3E3 is about 550 meters for a point target and 800 meters for an area target. A larger muzzle velocity would increase the range, while air resistance would decrease it.
Step-by-step explanation:
The maximum effective range of the M16A3E3 for a point target is about 550 meters, while for an area target it is around 800 meters.
The maximum effective range refers to the distance at which the weapon can accurately hit a target. It is influenced by factors such as muzzle velocity, bullet trajectory, and bullet drop due to gravity.
A larger muzzle velocity would increase the maximum effective range, as the bullet would travel faster. Air resistance would decrease the range by slowing down the bullet more quickly.
