There are a wide variety of rounds for this system. Here's a few.
25mm M790's family of ammunition
This round is fired from the Bradley Fighting Vehicle (BFV) and the Marine Lightly Armoured Vehicle (LAV). The M791 APDS-T is used for armour penetration and the M792 HEI-T is used for anti-personnel and soft target defeat. These combat rounds received excellent feedback during Operation Desert Storm.
The M791 APDS-T round possesses the accuracy and performance necessary to defeat today's threats. Its high velocity, coupled with a low time of flight, assures effective results at extended ranges.
The M792 HEI-T round offers the accuracy and performance needed for light materiel and fire suppression. This round is fuzed with the M758 Point Detonating Self-Destruct (PDSD) fuze, developed and produced exclusively by Alliant Techsystems. The M758 provides superior arming delay, graze and extended range sensitivity, and self-destruct compared to existing medium caliber fuzes.
The M793 TP-T is a low cost, target practice cartridge, ballistically matched to the M792 HEI-T round.
All rounds are interchangeable with the M242 Bushmaster gun, the KBA B02B automatic cannon, the GE525 (GAU-12/U) Gatling gun, and other NATO-qualified systems.
