Thirty-millimeter ammunition is typically not used against personnel, but rather as an anti-material or armor-piercing round. Rounds of this size can be effective against lightly armored vehicles as well as fortified bunkers. It is also a popular caliber for shipboard close-in weapons systems, such as the Russian AK-630 and Dutch Goalkeeper CIWS.

The Armed Forces of the Russian Federation use their 30 mm weapons in a variety of vehicles, including the Su-25 attack aircraft, Mi-24 helicopter, Mi-28 attack helicopter, Ka-50 attack helicopter, and the BMP-2, BMP-3, and BTR-90 infantry fighting vehicles. The most modern anti-aircraft gun systems in use by Russia are 30 mm. The U.S. military uses 30 mm weapons in their A-10 Thunderbolt II ground-attack aircraft , AC-130 gunship (AC-130W Stinger II and AC-130J Ghostrider variants), and AH-64 Apache attack helicopter. It was going to be used in the Expeditionary Fighting Vehicle until the project was canceled.

Thirty-millimeter ammunition generally comes in three varieties: armor-piercing (AP), high-explosive (HE), and target practice (TP) rounds. Both AP and HE cartridges commonly possess incendiary or tracer characteristics.
