What is the approximate firing range of an 81mm mortar?

~80-5,800 meters ~100-3,800 meters ~200-6,000 meters ~60-2,500 meters

Correct Answer:

~80-5,800 meters

Explanation:

An 81mm mortar’s range comes from the combination of propellant charge and elevation, which set the muzzle velocity and trajectory. You can fire as close as roughly 80 meters, but the round must travel far enough that the weapon’s blast and percussion don’t endanger friendly forces. With standard high‑explosive rounds and the maximum practical propellant charge, the projectile can reach about 5,800 meters. That defines the typical firing envelope: roughly 80 to 5,800 meters. The other ranges shown in the options don’t match this practical spread—some stop far short of the maximum, while others start too close for safe or effective use.
