What is the purpose of a dummy 20 mm round?

The purpose of a dummy 20 mm round is primarily for drill or testing the feeder assembly. Dummy rounds, which are inert and do not contain explosive components or propellant, are specifically designed to simulate the weight and shape of live ammunition without the risk associated with actual munition. This allows personnel to practice loading and unloading ammunition, as well as to ensure that the equipment, such as guns and feeder assemblies, functions properly without the hazards posed by live rounds.

Using dummy rounds for training helps maintain safety while providing a realistic training environment. They can be employed in various exercises where the handling and management of ammunition are critical skills that need to be practiced. This use contributes to the effectiveness and readiness of military personnel when they transition to handling actual live ammunition in operational scenarios.
