23mm 300 ZU-23-2

The ZU-23-2, also known as 'Sergey', is a Soviet-designed towed 23mm anti-aircraft twin-barreled autocannon. It is widely used by many armies for air defense against low-flying targets and for ground support.

Developed in the late 1950s to counter increasingly fast low-altitude jet aircraft, this weapon system officially entered Soviet service in 1960 as a more powerful successor to the 14.5mm ZPU series. It saw its first major combat deployments during the Vietnam War and later became a staple of the Soviet-Afghan War, where crews frequently mounted it on trucks to create highly mobile fire-support platforms. Decades after its introduction, the system remains in active service globally, often upgraded with modern optical-electronic targeting systems or integrated into improvised fighting vehicles in contemporary conflicts.
