Types of 25 mm ammunition


Several sub-types of the NATO 25 mm ammunition are available—the most common being armor-piercing, high-explosive, sabot, tracer, and practice rounds. Cartridges are usually composed of a combination of the aforementioned categories. For example, the M791 is an armor-piercing discarding sabot with tracer (APDS-T) round. It is used against lightly armored vehicles, self-propelled artillery, and aerial targets such as helicopters and slow-moving fixed-wing aircraft.
