ZSU-23-2

The record name ZSU-23-2 appears to refer to the Soviet ZU-23-2 twin 23 mm anti-aircraft gun rather than a standard self-propelled ZSU designation. The ZU-23-2 was developed in the late 1950s as a light towed air-defense weapon and became one of the most widely exported Soviet anti-aircraft guns. It is often truck-mounted or installed on improvised vehicles, which may explain the database's self-propelled-gun category.

The system uses two 23x152 mm autocannon barrels on a lightweight mount with optical sights and a high combined rate of fire. It is simple, rugged, and easy to tow or mount on trucks, armored vehicles, or static positions. Its air-defense effectiveness against fast modern aircraft is limited, but it remains useful against helicopters, low-flying aircraft, drones, light vehicles, and infantry positions at short range.

Operationally, ZU-23-2 guns remain common because they are cheap, mobile, and easy to sustain. Many forces use them less as classic anti-aircraft artillery and more as high-volume direct fire against ground targets or low, slow aerial threats such as drones. The system's survival across many conflicts reflects practical utility rather than modern sophistication, and the article should make clear that ZSU-23-2 is probably a naming variant rather than the formal Soviet designation.
