What kind of rounds are used for training purposes with mortars?

For training purposes with mortars, dummy or inert rounds are specifically designed to provide a safe and effective way to practice without the risks associated with live ammunition. These rounds replicate the weight and shape of actual rounds but do not contain explosive components. This allows personnel to gain experience in loading, aiming, and firing mortars while minimizing safety hazards. Using dummy rounds helps in understanding the ballistic properties and handling characteristics of the mortar system without the complications of live fire, allowing for realistic training scenarios and drills.

While live rounds and explosive rounds are essential for actual combat operations, they present significant safety concerns during training sessions. Sub-caliber rounds, which are smaller and typically used for simulating larger caliber systems, are not as commonly used for standard mortar training compared to dummy rounds.
