What type of sight is commonly used with the 81mm mortar?

The most commonly used type of sight with the 81mm mortar is an optical sight. Optical sights provide a precise aiming point through magnification and reticle systems, allowing for improved accuracy and target acquisition over varying distances, which is critical for indirect fire support like that provided by mortars. This type of sight enhances the operator's ability to determine range and make necessary adjustments, ensuring that the rounds impact the intended target effectively.

While red dot sights, laser sights, and infrared sights have specific applications in different combat scenarios and with different weapon systems, the optical sight stands out in mortar operations due to its design that supports the unique targeting needs of mortar crews, particularly in complex terrains and varying environmental conditions.
