SPAAG stands for Self-Propelled Anti-Aircraft Gun. SPAAGs are usually multi-cannon turrets with a high rate of fire mounted on top of APC or light tank chassis. The concept was pioneered mainly by the Germans during World War 2, with their flakpanzer series ("Kugelblitz", "Coelian", etc.).
ZSU is the Russian acronym for SPAAG ("Zenitnaya Samokhodnaya Ustanovka").
