An oscillating turret is a form of turret for armoured fighting vehicles, both tanks and armoured cars. The turret is unusual in being made of two hinged parts. Elevation of the gun relies on the upper part of the turret moving relative to the lower part.

The AMX-13 is a French light tank produced from 1952 to 1987. It served with the French Army, as the Char 13t-75 Modèle 51, and was exported to more than 26 other nations. Named after its initial weight of 13 tonnes, and featuring a tough and reliable chassis, it was fitted with an oscillating turret built by GIAT Industries with revolver-type magazines, which were also used on the Austrian SK-105 Kürassier. Including prototypes and export versions, over a hundred variants exist, including self-propelled guns, anti-aircraft systems, APCs, and ATGM versions.
