The WZ-523 is a six-wheeled Chinese armored personnel carrier designed to be amphibious. Built on the chassis of the Hanyang HY472 truck, it can carry a crew of three and seat up to eight additional passengers. Two primary models were produced—one with a roof-mounted 12.7mm heavy machine gun, and the other with a small turret armed with a 35mm grenade launcher and a 7.62mm co-axial general purpose machine gun. An export model that entered service in 2008 as a fire support vehicle was also marketed successfully to the Namibian Army; this is armed with a 73mm 2A28 Grom smoothbore cannon using the same turret as the Soviet BMP-1 infantry fighting vehicle.
