What type of mortar is often used for demonstration and practice?

The type of mortar that is commonly used for demonstration and practice purposes is blank ammunition mortar. Blank ammunition mortars are designed to fire rounds that do not contain explosive payloads, making them safe for training environments where soldiers can practice the mechanics of mortar operation without the risks associated with live rounds. This allows for realistic training scenarios, including the loading, aiming, and firing procedures.

In contrast, live fire mortars contain explosive ordnance and are intended for actual combat situations, which makes them unsuitable for practice or demonstration due to safety concerns. Similarly, smoke mortars and illumination mortars serve specific tactical purposes—producing smoke for concealment or providing light for illumination during nighttime operations—but they are also not appropriate for training maneuvers meant to simulate the basic operational aspects of mortar systems in a safe and controlled environment. Thus, blank ammunition mortars provide an ideal solution for instructing personnel without exposing them to the hazards of live explosives.
