The ZBD-86 (also known as WZ-501 or Type 86 IFV) is a Chinese unlicensed copy of the Soviet BMP-1, acquired from Egypt in the 1980s. The vehicle is practically identical to its Soviet counterpart with even its engine being a copy of the original UTD-20, but the Malyutka ATGM launcher was replaced with the HJ-73 Red Arrow missile launcher. By the time it entered service in 1992, it was already obsolete.
