What type of projectiles can a 81mm mortar fire?

The 81mm mortar is a versatile weapon system that is capable of firing a variety of projectiles designed for different tactical situations. High explosive rounds are commonly used to inflict damage on enemy personnel and equipment, while smoke rounds provide visual concealment on the battlefield, obscuring movement and positions from the enemy. Illumination rounds are used to light up a specific area during nighttime operations, allowing troops to see and engage targets more effectively.

The inclusion of smoke rounds in the correct answer highlights the mortar's ability to provide cover and obscure lines of sight, which is crucial for tactical maneuvers in combat. Additionally, illumination rounds play a vital role in enhancing situational awareness in low-light conditions, making it a fundamental component of military operations.

While other projectile types like shrapnel or fragmentation rounds may have their specific uses, the combination of high explosive, smoke, and illumination rounds is particularly significant for the range of operations typically supported by an 81mm mortar, including direct fire support and area denial strategies.
